The Ford Super Duty is a series of trucks manufactured by the 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, F-350, and F-450 trucks, while the previous 1987–1997 F-Super Duty chassis cabs were replaced by the F-450 chassis cab and F-550 Super Duty.
