The tenth generation of the Ford F-Series is a line of pickup trucks produced by Ford from the 1997 to 2004 model years. The first ground-up redesign of the F-Series since 1980, the tenth generation saw the introduction of an all-new chassis and a completely new body. In a significant model change, the tenth generation was developed only for the F-150 (and later a light-duty F-250), with the ninth-generation F-250 and F-350 replaced by the all-new Ford Super Duty variant of the F-Series for 1999.
