The fourth generation of the Ford F-Series is a line of pickup trucks and commercial trucks that were produced by Ford from the 1961 to 1966 model years. Lower and wider than the previous generation, the fourth-generation F-Series marked several design changes to the F-Series, distinguished by bed sides matching the hood line and window sill in height. The model line returned to two headlights, a change that remained in place for over 50 years.
