Dentside is the affectionate nickname for sixth-generation Ford F-100 trucks produced from 1973 through 1979. The name comes from the concave body-side character line, a sculpted indentation that runs along the doors and bed, giving the appearance of a long, shallow dent. This was a deliberate styling choice that distinguished the generation from the raised feature line of the preceding Bumpside trucks.
The Dentside generation brought significant improvements in comfort and refinement. These trucks offered the new SuperCab extended cab option starting in 1974, improved sound insulation, and better interior appointments. Engine choices included the 300 Six, 302 and 351 Windsor V8s, and the 351M and 400M Modified engines.
Dentsides are the last generation to carry the F-100 designation, as Ford transitioned to the F-150 in 1980. This makes late Dentsides historically significant as the end of an era. They are popular build candidates because of their relatively modern driving dynamics, wide engine bay that accepts many swap options, and comfortable cabs. Rust in the cab corners, rocker panels, and bed floor is the most common issue facing restorers of these trucks.
