The Ford F-Series Super Duty (often shortened to Ford Super Duty) is a series of trucks manufactured by Ford Motor Company. Introduced in 1998 for the 1999 model year, the F-Series Super Duty trucks marked the addition of a heavy-duty pickup to the Ford F-Series range with the new versions of the F-250 and F-350 pickups, while the previous 1987–1997 F-Super Duty chassis cabs were replaced by the F-450 and F-550 Super Duty.

The Super Duty trucks utilize a distinct chassis from the lighter F-150, with heavier-duty chassis and suspension components to allow for higher payload and towing capacities; additionally, the product line continued the use of Ford PowerStroke diesel engines. With a GVWR over 8,500 lb (3,900 kg), Super Duty pickups are class 2 and 3 trucks while chassis cab trucks are class 4 and class 5. The F-Series Super Duty has been used as the base chassis of the Ford Excursion full-size SUV.

Ford F-250 to F-550 Super Duty trucks are assembled at the Kentucky Truck Plant in Louisville, Kentucky, while medium-duty F-650 and F-750s are assembled at Ohio Assembly in Avon Lake, Ohio (prior to 2016, medium-duty trucks were assembled in the Blue Diamond Truck joint venture with Navistar in Mexico). As of 2016, the Ford Super Duty is sold in the United States, Canada, Mexico, Venezuela (F-250 and F-350), Suriname, Brazil (F-350/F-4000), Argentina (F-4000 only), Angola (F-250 and F-350), Cambodia, the Middle East, and Iceland (F-350 only) in LHD only. In Suriname, even though traffic is on the left side of the road, the import and registry of left hand drive vehicles is allowed. In Australia, it was officially imported in right hand drive from Brazil between 2001–06, however as of 2007, Ford no longer offers the Super Duty in Australia.

In 1958, Ford introduced the Super Duty family of V8 engines. Built specifically for trucks, the 401, 477, and 534 cubic-inch gasoline V8s were the largest-block V8 engines ever built by Ford Motor Company (other than the 1100 cu in GAA, developed for the US Army as a tank powerplant; this however was a 'cut-down' V-12, with a 60° V-angle, and was not originally designed as a V-8), and were the largest mass-produced gasoline V8 engines in the world. To showcase the engine launch, the "Big Job" conventional truck variants of the F-Series were re-branded as Super Duty,^[2] a name added to other Ford trucks as well. Alongside the Ford C-Series and H-Series cabovers, the N-Series conventional adopted the Super Duty name.^[3] Although its poor fuel economy would prove uncompetitive against diesel engines, the durability of the Super Duty would keep it in production into 1981.

In 1987 Ford would revitalize the name as a Class 4 truck badged as "F-Super Duty", Manufactured as a chassis cab with the frame open for a bed that would suit its future application, these trucks would be equipped with the 7.5 liter gasoline engine or a 7.3 liter IDI diesel engine. The weight and class of these trucks would make them the heaviest trucks in the F-Series line at the time.

Following the redesign of the 1997 Ford F-150, the Ford F-Series began a transition in its layout. In response to the changing demographics of pickup truck purchases during the 1980s and 1990s, Ford shifted the design of the F-150 separate from the larger F-250 and F-350 (which remained in production). While still a full-size pickup under the skin, to expand its appeal among consumers, the F-150 adopted carlike aerodynamics and convenience features. To market a truck that appealed towards commercial buyers, fleet buyers, and users who tow, Ford sought to create a separate, dedicated heavy-duty truck platform (in place of using one chassis for all of its trucks). By expanding into two separate but related platforms for F-Series trucks, the inevitable compromises inherent in offering a wide range of load-carrying capacities were avoided. The F-250HD lasted into 1997 (alongside a separate 1997/1998 F-250 based upon the F-150); the F-350 pickup was put on hiatus after 1997.

Beginning production in early 1998 for the 1999 model, the Ford F-Series Super Duty consisted of the F-250 pickup truck, F-350 pickup truck and chassis cab, and introduced the F-450 and F-550 chassis cab trucks (see below). The Super Duty trucks would be produced with three cab configurations: two-door standard cab, 2+2 door SuperCab, and four-door crew cab. The SuperCab configuration of the Super Duty marked the introduction of two standard rear-hinged doors on the extended cab, a feature also adopted by the F-150 and Ranger/Mazda B-Series for 1999. The standard cab was produced with an 8-foot bed; SuperCab and crew cabs were produced with a 6 3/4-foot bed, with an 8-foot bed optional. Two-wheel drive was standard, with four-wheel drive as an option; on F-350 pickup trucks, a dual rear-wheel axle was optional with either drive configuration.

Styled by Andrew Jacobson (designer of the 1997 Ford F-150) and Moray Callum,^[5] aside from taillamp lenses and the tailgate, the Super Duty F-Series trucks share no visible exterior parts with the Ford F-150. Under the skin, only the base-equipment 5.4L V8 and 4R100 transmission are shared. While sharing the similar aerodynamic cab design of its smaller counterpart, the exterior of the Super Duty trucks are much different forward of the windshield. While an influence often compared to the 1994–2001 Dodge Ram, the Super Duty also derives elements of styling from much larger Ford trucks, including the Ford LTL-9000 and Aeromax, with a raised hoodline, large grille, and low fenders. A feature drawn from 1996 redesign of the Louisville/Aeromax was in the design of the side window openings: the front portion is lowered, allowing for increased side visibility (as well as larger sideview mirrors). To improve aerodynamics over metal-framed mirrors, manual-telescoping trailer tow mirrors were available as an option. As an industry first, 2 large complete ring-style front tow hooks were included. A minor update occurred in the 2002 model year which saw a new instrument cluster with a digital odometer.

For the 2005 model year, the Ford Super Duty trucks were given exterior and interior updates. For the exterior, a new grille, front bumper, and headlights were introduced alongside the introduction of a locking tailgate for all pickup trucks. Under the skin (with thicker frame rails), updated Triton gasoline engines were introduced with higher engine output and larger alternators; in response to the increased power, all trucks were given 4-wheel disc brakes (with two-piston calipers). To accommodate the larger brakes, 17-inch wheels became standard, with 18-inch wheels optional (on single rear-wheel trucks); forged Alcoa wheels were an option. The long-running Twin I-Beam front suspension continued on two-wheel drive trucks.

To the interior, several changes were made to improve functionality for end-users. Along with the addition of a driver-side glove compartment, the truck added the option of dashboard-mounted auxiliary switches (for owners who fit equipment such as snowplows, winches, and auxiliary lights); these are switches that were typically user designed. For users that tow, a new option was Ford TowCommand, a Trailer brake controller built into the dashboard, allowing it to integrate with the ABS system and engine computer from the factory.

During its production, the first-generation Ford F-Series Super Duty was sold with two gasoline and two diesel engines.

Replacing the overhead-valve engines used in previous F-Series models, for the Super Duty, Ford transitioned to the Triton overhead-cam engine family (truck versions of the Ford Modular engines).

At its launch, the standard engine in the Super Duty was a Triton V8. Producing 255 hp/350 lb-ft of torque, the SOHC 16-valve V8 was shared with the F-150 and Ford E-Series. During 1999, the engine was retuned to 260 hp. In 2005, the cylinder heads were redesigned to 3-valve design, converting it to a 24-valve V8; output was increased to 300 hp/365 lb-ft of torque.

As a replacement for the long-running 7.5L/460 V8, for the Super Duty, Ford introduced a Triton V10. A SOHC 20-valve engine, the V10 produced 310 hp/425 lb-ft of torque. In 2005, the V10 would also receive 3-valve cylinder heads, increasing its output to 362 hp/457 lb-ft of torque.

Both the V8 and V10 Triton engines are designed with a fail-safe cooling system to protect the engine in case of major coolant loss. If the engine overheats, the engine will operate on half of its cylinders. Alternating back and forth between each set of 4 (or 5) pistons, the set that is not receiving fuel and ignition is operating to pump air through the engine to lower its temperature. Although engine output is limited, dependent on upon vehicle load, outside temperature, and current road conditions, the system is designed to allow the vehicle to travel a short distance to obtain service or to reach a repair facility.

Available in both F-250 and F-350 pickup trucks as well as F-450 and F-550 chassis cabs, the F-Series was sold with optional PowerStroke V8 diesel engines produced under its joint venture with Navistar International.

At its launch, the Super Duty F-Series was sold with the 7.3L Power Stroke V8. Initially producing 235 hp/500 lb-ft of torque, the engine was retuned in 2001. Versions equipped with an automatic transmission produced 250 hp while manual-transmission examples produced 275 hp; with either transmission, the engine produced 525 lb-ft of torque. As the 7.3L V8 was no longer able to comply with emissions regulations for diesel engines, it was discontinued midway through the 2003 model year.

As a running change during the 2003 model year, the 6.0L PowerStroke V8 was introduced as the replacement for the previous 7.3L V8 in LHD markets supplied with the American-assembled trucks while RHD ones supplied from Brazil kept the 7.3 until 2005. As before, the engine continued to be produced by Navistar. A 32-valve pushrod engine, the 6.0L V8 featured a single variable-vane turbocharger. While a smaller-displacement engine than its predecessor, its output is higher than the 7.3L, providing 325 hp/560 lb-ft of torque (in 2005, the torque increased to 570 lb-ft). Due to problems with the head bolts Navistar re-designed the engine with reinforced heads, more torque and, power releasing the new design in 2005-6. As with its predecessor, the 6.0L would end its production run due to tighter emissions requirements, replaced as part of the Super Duty redesign for the 2008 model year.

The 6.0L Powerstroke was the target of a class-action lawsuit, alleging the engines were defective. Ford settled the lawsuit with owners and former owners of 6.0L diesel-equipped Super Duty trucks and E-Series vans in 2013, by reimbursing them for the cost of repairs to the EGR system, fuel injectors, and turbocharger, which were common failure points.^[6]

Four transmissions were available. Several configurations of ZF5 five speed manual transmissions were offered: Small block pattern, big block pattern, and diesel. Close ratio and wide ratios were available, as well as 4wd and 2wd configurations with the exception of integrated driveshaft brake 2wd versions using the 4x4 style transmission. Earlier s5-42 versions were rated to 570 Nm (420 ft lbs) of torque, while later s5-47 versions were rated to 636 Nm (470 ft lbs). ZF 6-speed manual for diesel engines. An optional 4R100 4-speed automatic was available for either the gas or diesel engines, later being replaced with the TorqShift 5-speed automatic. The 5-speed automatics are rated at exactly 1,000 lb (450 kg), enabling higher towing capacity than trucks with the standard 5/6-speed manual transmission. The 6-speed manual transmission comes with an integrated PTO.

The Torqshift 5-speed 5R110 automatic transmission replaced the 4-speed in the 2003 model year diesel trucks in order to compete with the Allison 1000 series from General Motors; it was paired with the new 6.0 L diesel engine. The TorqShift design in fact has six forward ratios, but only five are advertised, with the 'hidden' gear only used in extreme cold weather. The TorqShift 1st to 5th gear ratios are 3.11, 2.22, 1.55, 1.00, and 0.71:1. It also utilizes an alternate 4th gear, overdrive on 2nd gear of the 3-speed automatic component (0.72 x 1.55), that is 1.10:1 that is used under cold start conditions to aid engine and transmission warm up. On the TorqShift, once the Tow/Haul mode is activated it can help increase a driver's control when towing large loads up and down steep grades and automatically minimizes shifts and maximizes available torque. Upon descent, the Tow/Haul mode utilizes engine braking to help extend brake life and improve driver control. An adaptive shift function monitors the TorqShift's performance over its lifetime, and adjusts shift pressures in real time to assure consistent shift feel and compensate for wear. For ease of maintenance, the TorqShift's oil filter is an easily serviced cartridge design that was usually mounted on the passenger side behind the front bumper. Also the TorqShift's larger fluid lines and a larger transmission oil cooler help to assure cooler operating temperatures, even under the most demanding conditions. This was Ford's first automatic transmission to feature PTO. The transmission can be equipped with an integrated PTO provision (which automatically locks the torque converter providing power to the PTO gear when the operator turns on the PTO switch).^[7]

On 4x4 models there is a choice of a manual chain-driven transfer case floor shifter with manual front locking hubs or Electronic-Shift-On-the-Fly (ESOF, a $185 option over the manual) dash knob with vacuum activated automatic and (in case of failure) manual override front hubs. The optional FX4 models are basically a standard 4x4 with an Off Road package that includes a few extras like upgraded heavy duty Rancho shocks, added skid plates for the fuel tank and transfer case, and two "FX4" decals on both back bed-sides instead of the standard "4x4". For all 4x4 models, the 2-speed transfer case 4x4-LOW range has a gear reduction of 2.72:1. Brazilian and Venezuelan versions had only the ESOF transfer case.

For the first-generation Super Duty range, Ford used several different suspension configurations, depending on the model of truck. All models have heavy-duty 3" wide leaf springs and staggered shock absorbers. A standard stabilizer bar is included on dual rear-wheel models and an option on single rear-wheel versions. An optional slide-in camper certification package with heavier-duty springs was available on single rear-wheel models. All versions of the Super Duty trucks came equipped with four-wheel disc brakes.

On two-wheel drive F-250 and F-350 pickups, the Twin I-Beam independent front suspension with coil springs was used; their four-wheel drive counterparts were equipped with solid front axle (Dana 50 and Dana 60) with leaf springs. In 2005, the front suspension was updated as four-wheel drive trucks were converted to front coil springs; to reduce unsprung weight, the mounting of the front sway bar was changed to the frame instead of the front axle. The manual locking hubs on Super Duty trucks are made by Warn.^[8]

On the F-250 and F-350, the rear suspension used heavy-duty 3" wide leaf springs and staggered shock absorbers; a standard stabilizer bar was included on dual rear-wheel models. Single-rear wheel versions were fitted with a 10.5-inch (270 mm) Sterling 10.5 axle 35-spline axle with choices of conventional or limited-slip differentials; initially developed for previous-generation Ford trucks, it was strengthened for use in the Super Duty. In dual-rear wheel F-350s, the rear axle was a Dana 80.

On F-450 and F-550 cab-chassis trucks, the Dana 60 front axle was replaced with a Dana Super 60 in 2005. The rear suspension on 2011-2014 F-450s Pickup used Dana 80 axles and 2008-2010 & 2015-2018 F-450s Pickup used Dana S 110. F-450 cab-chassis used a Dana S 110. F-550s used a Dana 135 from 1995 to 2004; in 2005, the Dana S 110 rear axle was added to the F-550.

The Dana 50 axle featured on most F-250 Super Dutys differs greatly from the early models. The Dana 50 started out as a Twin Traction Beam axle (much like independent suspension) in 1980. This lasted all the way to 1997 models. The Super Duty models then used a solid axle version of this axle. The ring, pinion, carrier and u joints all remained the same however. The Dana 50 was phased out of the trucks in 2004, in favor of the Dana 60 and was last used in the Ford Excursion.

Throughout its production run, the first-generation 1999-2007 Ford F-Series Super Duty was offered in three main trim levels:

The base XL was the "work truck" trim level of the F-Series Super Duty. Its standard features included a manual transmission, an AM/FM stereo with two front door-mounted speakers, a heater and blower, vinyl-trimmed seating surfaces with bench seats, steel wheels with black center hubs, black front and rear bumpers, a black "egg-crate" front grille, and manual windows and door locks. Optional features that were offered on this trim level included cloth-trimmed seating surfaces or vinyl-and-cloth-trimmed seating surfaces, power windows and door locks, an AM/FM stereo with cassette player (later, a single-disc CD player instead of a cassette player) and four speakers, chrome front and rear bumpers as part of an XL Decor Group, an automatic transmission, and air conditioning.

The mid-range XLT was the most popular trim level of the F-Series Super Duty. It added the following features to the base XL trim level: an AM/FM stereo with cassette player (later, a single-disc CD player instead of a cassette player) and four speakers, cloth-trimmed seating surfaces, bright center wheel hubs, chrome front and rear bumpers, a chrome "egg-crate" front grille with black inserts, power windows and door locks, and air conditioning. Optional features that were offered on this trim level included aluminum wheels, keyless entry (later, this option became standard equipment on this trim level), an AM/FM stereo with both a cassette player and a single-disc CD player (later, a six-disc, in-dash CD changer), an automatic transmission, and a power-adjustable front driver's bench seat.

The top-of-the-line Lariat was the most luxurious trim level of the F-Series Super Duty. It added the following features to the mid-range XLT trim level: an AM/FM stereo with both a cassette player and a single-disc CD player (later, a six-disc, in-dash CD changer), leather-trimmed seating surfaces, chrome-clad (later aluminum) wheels and center wheel hubs, keyless entry, a security system, electronic climate controls, a power front bench seat with fold-down center armrest, wood interior trim panels, and a chrome front grille with chrome inserts. Available options included two-tone exterior paint, color-keyed grille insert as well as front & rear bumpers, bucket seats replacing the bench seat, heated front seats, and an automatic transmission (which later became standard on this trim level).

There were multiple special edition Super Duty models that were offered.

For 2003, a special Centennial Edition Super Duty Crew Cab was offered to celebrate the 100th anniversary of Ford Motor Company. The truck could be ordered only as a Crew Cab, but a choice of bed lengths, DRW or SRW and gasoline or diesel engine were available. The Centennial Edition offered the following standard equipment: Monochromatic Black Clearcoat exterior, Premium Verona-grain Imola leather seating finished in Two-Tone Parchment, Special Centennial Edition badging and a commemorative keychain and wristwatch. The Centennial Edition also came with special leather-bound owners manual with the embossed signatures of Henry Ford, Edsel Ford, Henry Ford II, and William Clay Ford, Jr. ^[9]

Ford offered a special Harley-Davidson Super Duty truck from 2004-2007. Available only on SRW models, the Harley package could be had with either SuperCab or Crew Cab and customers could choose either V10 gas or 6.0L Powerstroke turbo diesel power. Based upon the Lariat trim, Harley's had a unique black leather interior, with the Bar and Shield logo adorning the front and rear captains chairs (SuperCab models had a rear bench). Heated seats, a leather-wrapped multifunction steering wheel, power adjustable pedals, and power-adjustable heated mirrors round out the standard equipment. Unique spun-metal gauge faceplates, embroidered carpeted floor mats, and a leather-wrapped console lid with individually serial numbered badging round out unique interior appointments. 2004 Harley's could be had with three unique paint schemes, Competition Orange/Black Clearcoat two-tone, Dark Shadow Gray/Black Clearcoat two-tone or a Black Clearcoat solid paint job. Unique pinstriping was found on all three color options.

2005 saw changes to the Harley package corresponding with the refresh of the F-250 and F-350 Super Duty model. No longer could you order a SuperCab Harley-Davidson and the 5.4L V8 was added as the base engine for the package. New unique black trimmed headlights, billet-style grille, and 20" wheels were made standard. Gone was the two-tone paint jobs, but optional was painted ghost flames. 2005 models could be had in two color options, Black or True Blue Metallic. The interior stayed largely the same, with luxurious black leather captains chairs in the front and rear and Harley Bar and Shield badging galore, but the truck saw the same interior updates as other '05 Super Dutys.

To bridge the gap between the pickup line and the much larger medium-duty F-650/F-750, Ford introduced the F-450 and F-550 variants of the Super Duty; with an available GVWR from 17,950-19,500 lbs, it pushes the Super Duty into the Class 5 truck market. Available only as a chassis cab for commercial upfitters, both versions were fitted with dual rear wheels.

While largely aimed at fleet buyers, F-450 and F-550 were configurable in XL, XLT, and Lariat trim levels available to Super Duty pickup buyers. The sole gasoline engine was the 6.8L V10 while the 7.3L PowerStroke was the diesel option; in 2003, this was replaced by the 6.0L PowerStroke.

In 2005, the F-450 and F-550 received further updates to the exterior than the rest of the Super Duty line, with an extended front bumper and front fenders; the F-550 received a "wide-track" front axle to sharpen its turning radius.

The Ford F-350 Super Duty first generation was also assembled in Venezuela as a commercial small truck from 1999 to 2010. For this market the F-350 featured the 5.4L V8 Triton engine, a 5-speed manual transmission, and a choice of 4x2 or 4x4.

Ford Super Duty trucks were built in Brazil, with different engines than its North American counterparts and fewer options, initially between 1999 and 2011, with a limited reintroduction of the F-350 in 2014. The dual-rear wheel variant of the F-350 is known locally as F-4000. They were widely exported to Australia (F-250 and F-350), South Africa (F-250) and Argentina (F-250, rebadged as F-100, and the F-350 DRW rebadged as F-4000), usually following the Brazilian specification (with an obvious change of the cockpit location in the versions targeted to Australia, South Africa and other RHD markets) but Australia had a wider range of options in pair with its American counterparts, including automatic transmission and the V8 engines.^[10] Supercab extended-cab bodystyle was never officially available in Brazil and regional export markets (Uruguay and Argentina), but was made in RHD for export to Australia. South Africa had only the MWM engine and 5-speed manual transmission, with the option of 2WD and 4WD for the single-cab while the crew-cab had 4WD as standard.

The second-generation Super Duty was to debut for model year 2007, but quality issues pushed it back to the 2008 model year. It features an all-new 6.4 L, 390.5 cu in Power Stroke Diesel V8 with piezo fuel injectors and sequential turbos to replace the problematic 6.0 L Power Stroke single-turbo Diesel V8. The new engine produces 350 hp (260 kW) and 650 ft⋅lbf (880 N⋅m) of torque.^[13] The vehicle had its first official showing at the Texas State Fair in 2006. Ford started taking orders in January 2007. The first 2008 F450 pickup, sold to the public, was delivered to Randy Whipple of Muskegon, Michigan in February 2007.

Located near the same dash area as the last generation (but slightly to the right and more directly below the radio), this generation of Super Duty has the same Ford TowCommand TBC (Trailer Brake Controller) and 4 AUX Upfitter switches as the last generation set-up.

There is an optional concealed slide-out step and swing-up hand grab bar in the rear tailgate for easy access.

Ford introduces its all new optional "Rapid-Heat Supplemental Cab Heater," only available on Super Duty trucks with the Diesel engine and TorqShift automatic transmission. In the winter, it quickly raises the cabin temperature to a comfortable level until the engine is warm enough to handle the job.

This 2nd generation of Super Duty includes the F-250 Super Duty (starting at $22,380), F-350 Super Duty (starting at $24,025), and the all new F-450 Super Duty (starting at $39,205). The F-250 and F-350 Super Duty basically has the same payload and towing specs as the last generation.

The model lineup for the 2010 F-250 and F-350 Super Duty is the XL (starting at $25,300), XLT (starting at $28,845), Lariat (starting at $36,420), Cabela's (starting at $42,655), King Ranch (starting at $42,955), and Harley-Davidson (starting at $56,925).

The model lineup for the F-450 Super Duty is the XL (starting at $44,145), XLT (starting at $49,525), Lariat (starting at $52,965), King Ranch (starting at $56,955), and the Harley-Davidson (starting at $62,625)

The FX4 model, which was once just an optional Off Road 4x4 package that could be added to any model in the lineup, is replaced by the 4x4 Off Road Package. The FX4 became a model of its own. It still had the same specs as the previous generation but with more of a sporty trim package. The FX4 model has been discontinued for the 2010 model year and has been reverted to an optional Off Road 4X4 package.

For 2008, Ford and Harley-Davidson once again joined forces to bring out a new special edition Super Duty. The Harley-Davidson package was available on both F-250 and F-350 Crew Cab SRW models. A gasoline engine was no longer offered with the package, instead, a 6.4L Powerstroke turbo diesel was standard. Unique black and dusted copper two-tone leather captains chairs with bar and shield logo, leather-trimmed center console, unique gauge cluster, and embroidered carpeted floor mats rounded out interior features. 20" wheels, billet-style grille, blacked out headlights, illuminated cab steps, power folding body-color Powerscope mirrors, rubber bed mat with Harley-Davidson logo and special badging were the exterior highlights. The truck could be ordered with two unique exterior themes, a black monochromatic look with bodyside graphics or a black and vintage copper two-tone with chrome dimensional boxside Harley-Davidson lettering. An Audiophile premium 8-speaker stereo with subwoofer was standard, while a DVD-based navigation system was optional. Rear seat DVD entertainment system with 8" screen was also optional, but could not be ordered with the power moonroof.

The Harley-Davidson package returned for 2009 with some changes. For the first time, the Harley-Davidson package was offered on the F-450 DRW pickup. The interior was trimmed in all black leather, instead of the two-tone for 2008. New colors were offered, Black with flame tape stripes, Black with Vista Blue painted flames or Dark Blue Pearl with Vista Blue painted flames. Ford's ToughBed spray on bedliner and a rearview camera was made options.

For 2010, only minor changes were made. Dark Blue Pearl was deleted from the color options in favor of Black with Tuxedo Black painted flames and the rearview camera was made standard. 2010 was the final year Ford offered a Harley edition Super Duty.

The same two gas engines are carried over and rated exactly the same from the 2nd generation. The 3-valve 5,408 cc (5.408 L; 330.0 cu in) V8 SOHC is standard. The 3-valve 6,802 cc (6.802 L; 415.1 cu in) V10 SOHC was still a $699 option over the 5.4L V8. The 4-valve Navistar 6.4 L (6400 cc, 390.5 cu in) V8 OHV Power Stroke diesel engine was the diesel engine option and was a $6,895 option over the 5,408 cc (5.408 L; 330.0 cu in) V8.

Some unique points to highlight of the 2008, 2009 & 2010 F-450 with a regular production pickup bed, which was only offered as a chassis cab before. It has 2 available axle ratios of 4.30 and 4.88:1. The F-450 Super Duty with the optional 'High Capacity Trailer Tow Package' increases the GCWR from 26,000 to 33,000 lb (15,000 kg). Maximum payload is 6,120 lb (2,780 kg). Maximum towing is 24,500 lb (11,100 kg) (4.88 axle ratio) / 20,500 lb (9,300 kg) (4.30 axle ratio). It comes standard with Crew Cab, 8-foot (2.4 m) long bed, DRW (Dual Rear Wheels), Limited Slip rear axle, 10-lug 19.5-inch (500 mm) Forged wheels made by Alcoa, Trailer Tow package, and the TowCommand TBC (Trailer Brake Controller). The only engine offered in the F-450 Super Duty is the 6.4 L V8 Power Stroke Sequential turbo diesel. The F-450 is equipped with a standard 6-speed manual or optional 5-speed TorqShift automatic transmission.

The Super Duty line received a large exterior upgrade that includes a new, bigger front fascia. Its engines were also upgraded to better compete with the new Silverado HD and Ram HD. Ford stated in the 2011 Chicago Auto Show that the 2011 trucks have the thickest gauge steel frame of any Heavy Duty truck, this was due to frame being the same design that debuted in 1999. The 2011 Ford F-Series Super Duty was awarded Truckin's "Topline Pulling Power" award for 2011. It also won Popular Mechanics best workhorse of 2011, and the best "Gear of the Year" in the trucks category.

The F-450 is able to tow 24,400 pounds (11,100 kg) and has a maximum payload of 4,920 pounds (2,230 kg). The F350 has a maximum 21,600 pounds (9,800 kg) of towing capacity and 7,110 pounds (3,230 kg) of payload.^[15] Each engine is mated to a 6R140 heavy-duty TorqShift six-speed automatic transmission.^[16] The Ford F-250, the F-350 and the F-450 all come with trim levels including the XL, XLT, Lariat, King Ranch, and Platinum.^[17]

The 2nd generation Facelift of the Ford Super Duty Trucks are assembled at Ford's Kentucky Truck Plant, with additional production for other countries in Venezuela and Mexico. In Venezuela the F-350 super duty is offered as a commercial use small truck cutaway featuring a 6.2L V8 gas engine with a 5-speed manual TREMEC transmission TR-4050 with a choice of 4x2 or 4x4 wheel drive. Since 2012 due to government regulations, the Venezuelan F-350 Super Duty is factory equipped to use both natural gas and gasoline. The F-250 super duty was also recently re-introduced in this market after ten years. It is being marketed using the same engine as the Venezuelan F-350, but only with a 6-speed automatic transmission, 4x2 or 4x4 wheel drive option in both single and double cab configurations.

A feature unique to the 2011 Super Duty is the addition of a locking differential. It is only available for the F-250 and SRW F-350 4x4 models with a rear Sterling 10.5 axle. It is a 390.00 USD option^[18] The diesel F-250 relies on vacuum-boost brakes, while the F-350 relies on Hydro-boost. Both gas versions of the F-250 and SRW F-350 use vacuum-boost. F-250 is a class 2 truck. While the F-350 SRW, F-350 DRW, & F-450 pickup are class 3. The F-250 and F-350 (SRW & DRW) have 13.66 inch front brakes and 13.39 inch rear brakes. The 2015-2016 F-250 and F-350 have 14.29 inch vented disc brakes on the front and rear axles as an improvement made for these model years. The F-450 pickup has 14.53 inch front brakes and 15.35 inch rear brakes. The F-450 has a wider track than the F-350. The F-450 remains available in class 4 as a Chassis Cab truck.

The trucks were once under investigation by the National Highway Traffic Safety Administration for steering failures, but the investigation revealed the failures were driver error and had nothing to do with design.^[19]

The 2011 Ford Super Duty is available with either a gas or diesel engine. The gas option is an E85-capable 6.2 L 2-valve SOHC V8, which puts out 385 horsepower (287 kW) and 405 pound-feet (549 N⋅m) of torque under 10,000 lb GVWR, 316 hp and 397 lb/ft of torque over 10,000 GVWR.^[20] The diesel is the new 6.7 L Power Stroke V8, producing 390 hp (291 kW) and 735 lb⋅ft (997 N⋅m) of torque.^[21] The new engine is an entirely Ford product, unlike previous diesels, therefore reducing development costs and shipping delays. The 6.8-liter V10 was dropped from the regular Super Duty models, however it is still an option with the F-450 and F-550 chassis cabs, mated with a 5-speed automatic transmission.

Shortly after the unveiling of the 6.7 L Power Stroke V8, GM unveiled the 2011 Chevrolet Silverado and GMC Sierra 3500HD with Duramax 6.6-liter turbodiesel V8, making 397 hp (296 kW) and 765 lb⋅ft (1,037 N⋅m) of torque. Ford quickly responded by boosting the output of the Power Stroke just months after its initial release, to 400 horsepower (298 kW) and 800 lb⋅ft (1,100 N⋅m) of torque. For customers who purchased a Super Duty with the original Power Stroke V8, Ford offered a free upgrade at dealerships to the new level of output.^[22] Power and torque was increased to 440 horsepower (328 kW) and 860 lb⋅ft (1,170 N⋅m) of torque on 2015 models.

No manual transmission is available in the United States, but in Mexico and Venezuela the F-350 is available with a 5 Speed Manual.^[23] Automatic transmission features a manual mode. The diesel engine's transmission optionally features a PTO and is a "live-drive" unit. "Live-drive" meaning the PTO is directly connected to the engines crankshaft, whereas the GM's Allison 1000 transmission and Ram's Aisin use a torque converter or clutch (depending on being an automatic or manual, respectively).

On the 6.7 L diesel engine only, there are 2 separate cooling systems:

A belt-driven pump mounted low on the driver side circulates the high-temperature coolant, while a separate belt-driven pump mounted higher on the passenger side circulates the low-temperature coolant.

The F-450 pickup is available only in a single configuration; a crew cab with a dual rear-wheel 8-foot bed. The only powertrain combination is the 6.7 L Powerstroke turbodiesel V8 mated to the six-speed TorqShift automatic transmission. Trims include the XL, XLT, Lariat, King Ranch, and Platinum.

The Ford Chassis cabs were updated using the new 2011 body style. Ford chassis cabs are still rated up to the industry maximum 19,500 pound Gross Vehicle Weight Rating. The Gross Combined weight was upped 2,000 pounds to 35,000 lb maximum; 5,000 pounds greater than the nearest competitor.^[24]

On September 24, 2015, Ford unveiled the 2017 Ford Super Duty line at the 2015 State Fair of Texas. This marks the first all-new Super Duty line since their 1998 debut, the frame is made from 95% high strength steel and the body (like the F-150) is made from high-strength military grade aluminum alloy.^[26]

For the first time since 1999, both the Super Duty and F-150 lines are constructed using the same cab^[26] to better compete with GM, Ram and Nissan's HD trucks. In a major departure, the stand-alone front grille and stepped front fenders seen since 1998 were eliminated from the exterior. The 2-bar grille introduced in 2011 was widened, integrating the headlights into its design.^[26]

In a switch to an aluminum-intensive body similar to the F-150, Ford created a potential 700 lbs (318kg) of weight savings; in spite of the addition of heavier-duty frame and driveline components, the 2017 Super Duty weighs in at up to 350 lbs (159kg) less than comparable 2016 models. Ford strengthened the frame and drivetrain with fortified drive shafts, axles, brakes and the 4WD transfer case.^[26] F-250 and F-350 pickups are built on a fully boxed frame; chassis-cab models are produced on a frame boxed up to the rear of the cab and of C-channel design rearward.^[26]

For 2017 production, the Super Duty line shares its powertrain lineup with its 2016 predecessor: a 6.2L gasoline V8, 6.8L V10 (F-450 and above), with a 6.7L diesel V8 available in all versions. The 6.2L gasoline V8 engine remains at 385 hp but torque rises from 405 lb-ft to 430 lb-ft. Additionally, the gasoline V8 produces its max torque at over 700 rpm less than the previous 405 lb-ft engine. The 6.7L diesel engine also remains at the same 440 hp (323kW) but torque increases from 860 lb-ft upwards to 925 lb-ft. The diesel engine now produces its peak torque at 1,800 rpm instead of the previous 1,600 rpm. The F-250 receives a TorqShift-G six-speed automatic while all other Super Duty trucks are paired with the 6R140 6-speed automatic.^[26] Crew Cab models will have a 34-gallon (128l) tank for the 6.75-foot bed and 48-gallon fuel tank for the 8-foot bed.^[27]

The interior design of the all-new Super Duty is similar to that of the 2015 Ford F-150, and shares many of the F-150's components.

Trim levels will continue to be XL, XLT, Lariat, King Ranch, and Platinum. The Limited trim would not debut for F-250 and F-350 until 2018. Cab configurations continue to be 2-Door Regular Cab, 4-Door Super Cab, and 4-Door Super Crew Cab (the F-450, in pickup truck configuration, is only available in this configuration), with Short Box (6' 9") and Long Box (8') bed lengths. The truck will be available in F-250, F-350, and F-450 pickup truck models, and F-350, F-450, and F-550 chassis cab models. All will be available in both 4X2 and 4X4 configurations. The F-350 will be the only model available in either Single Rear Wheel (SRW) or Dual Rear Wheel (DRW) configurations, the F-450 and F-550 will only be available in a Dual Rear Wheel (DRW) configuration, and the F-250 will only be available in a Single Rear Wheel configuration. Base prices in the U.S. range from $32,535 (F-250 XL) to $77,125 (F-450 Platinum).^[28] Full pricing is available on the manufacturer's website.

In September 2017, Ford announced that the 2018 F-450 would be the first $100,000 pickup truck, with the addition of the new Limited trim, which debuted on the Ford F150.^[29]

Ford has announced the engine lineup for the all-new Super Duty:

All engines will be paired with a "TorqShift" 6-speed automatic transmission, with the gasoline engines featuring 2 transmissions: 5-speed manual transmission (Chassis Cab F-350 Mexico Market only), Ford's all-new "TorqShift-G" automatic transmission.

The Super Duty will be available in eleven exterior color options.

On April 4, 2017, all Ford F-250 Super Duty trucks built between October 1, 2015 to April 1, 2017 were recalled due to the risk of improper and damaged rods in the parking brake and transmission allowing the truck to move while in park. This affected 52,000 trucks but no injuries or accidents were reported.^[30]

The 2020 Super Duty debuted at the 2019 Chicago Auto Show in February.^[31] It features a revised grille, rear, and interior trim. A new 7.3-liter gasoline engine is available, along with a 10-speed automatic transmission. The 2020 Super Duty goes on sale in fall 2019.

For 2020, Ford is reintroducing the F-600, a name that was late used in the late 1990s on a medium-duty truck. Based on the F-550 Super Duty, the F-600 Medium Duty will feature the body and cab of a traditional Super Duty Chassis Cab, with the underpinnings of the larger F-650 Medium Duty. Geared towards fleet buyers who require the capacity of an F-650 Medium Duty, though prefer the size and maneuverability of the smaller F-550 Super Duty. Available with either a 7.3L "Godzilla" gasoline V8 engine, or the 6.7L Powerstroke Turbodiesel V8 engine, paired with the "TorqShift" 10-speed automatic transmission and two-wheel-drive (4X2) or four-wheel-drive (4X4), the F-600 Medium Duty will go on sale in the Fall of 2019. ^[32]

For 2020, Ford reintroduces the Tremor name for the F-250 and F-350 Super Duty pickups. The nameplate was last used on the 2014 Ford F-150 as a sport appearance package. As an off-road oriented version of the F-250 and F-350 Super Duty, the Tremor models will compete directly with the Ram Truck 2500 Power Wagon, and will feature a suspension lift and upgraded tires and wheels from the factory. The trucks will also offer details not found on other Super Duty models, such as blacked out accents on the front grille, wheels, side emblems, and side mirrors, as well as 'Tremor' decals on the sides of the pickup box. Offered as a SuperCrew Cab model with a six-foot pickup box, and with four-wheel-drive (4X4), the Tremor will be equipped with the new 7.3L "Godzilla" gasoline V8 engine, while the 6.7L Powerstroke Turbodiesel V8 engine will be optional (the Ram Truck 2500 Power Wagon only offers a gasoline V8 engine). The trucks will come equipped with 35 inch tall off-road tires, eighteen-inch matte black-painted alloy wheels, and a new 10-speed "TorqShift" automatic transmission. Crawl ratios will be 53:1 for gasoline-equipped models, while the ratio for diesel-equipped models will be 44:1. The trucks will be able to ford water up to 33 inches deep, and will feature up to 10.8 inches of ground clearance. Another new feature for all Super Duty models (including the Tremor), is the Trailer Reverse Guidance System, which is similar to the Pro Trailer Backup Assist system in the Ford F-150, and allows for the driver to easily back their truck up to a trailer with little effort. The anew 2020 Ford F-250 and F-350 Super Duty Tremor models will go on sale in the Fall of 2019.^[33]

In 2000, Ford returned to the Class 6-7 truck market as it expanded the Super Duty line into the medium-duty segment. They developed a joint venture with Navistar International known as Blue Diamond Trucks, the F-650 and F-750 Super Duty were assembled in Mexico. While the chassis and other components would be common to both manufacturers, Ford and International would each source their own bodywork and powertrain; the cab for the Ford trucks would be common with other Super Duty models.

For the 2016 model year, the medium-duty truck range was given a major upgrade, following the end of the joint venture and the shift of the production to the United States. In place of outsourced engines and transmissions, the 2016 F-650 and F-750 now use a 6.8L gasoline V10, a 6.7L PowerStroke diesel V8, and a 6-speed automatic transmission all supplied by Ford.

From 2000 to 2005, the F-250 Super Duty served as a basis for the Ford Excursion sport-utility vehicle. Along with Chevrolet Suburban (and its Cadillac/GMC/Holden counterparts) and the International Harvester Travelall, the Ford Excursion was the longest non-limousine sport-utility vehicle ever sold.

The Excursion was available in three trim packages, XLT, Limited, and top-of-the-line Eddie Bauer. It could be had in two or four wheel drive and with three engine options, the 5.4L V8, 6.8L V10 or the Powerstroke V8 Turbodiesel. The Excursion was only available with an automatic transmission.

While the Excursion was largely sold in North America and Mexico, a similar vehicle was sold in Brazil from 1998 to 2012 as a second-party conversion of the Ford F-250 crew-cab (similar to the Centurion F-Series/Bronco conversions).

As a result of the heavy-duty frame and powertrain of its chassis, the Ford Super Duty has served as a donor platform for multiple types of armored vehicles, for civilian, law enforcement, and military use. Most versions are constructed using the Ford F-550 chassis cab. Examples include the Didgori-2, Lenco BearCat, Plasan Sand Cat, GAV Gurkha, and Conquest Knight XV.
