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.
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, 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.
