The tenth generation of the Ford F-Series is a line of pickup trucks produced by Ford from 1997 to 2004; it was sold from model years 1997 to 2004. In a major product shift in the Ford truck lineup, the F-250 and F-350 were split from the F-150. Released in early-1998 (model year 1999) the newly branded Super Duty trucks had a distinct body and chassis, while still branded as F-Series trucks.
