The Ford 'Highboy' F-250
The term 'Highboy' has been used to refer to 1967-1977.5 Ford F-250's, although 'Highboy' wasn't actually a Ford term.
The term 'Highboy' was more of a nickname that came about when Ford switched to a negative arch leaf spring for the 1977.5 model, making it 4-inches lower than the 1977 model.
For a Ford truck to be considered a 'Highboy', it should meet the following criteria:
- 1967-1977.5 Ford F-250 4x4
- Divorced Transfer Case (Not attached to the transmission)
- A Highboy will have (3) driveshafts
- The front spring pack will have a noticeable arch (1977.5 and later are flat)
- Rear springs are 2-1/4" wide. 1977.5 and later non-Highboy's will have 3-inch wide rear leafs.
Front axle choices in the Highboy were either the 8-lug Dana 44 or the low pinion Dana 60.
Engine choices were either the 6-cylinder or 360 2 bbl V-8. Steering was either manual or power ram assist.
F-150's built during that time are NOT considered a 'Highboy'. The F-250's built from 1977.5 and later are referred to as a 'Lowboy' because they sit lower than the 1977.
