Rough Country 400-70-7630 is a 2.5-inch lift kit for the 1970–1976 Ford F-100 4WD and the 1976 Ford F-150 4WD. It pairs lifted front coil springs and rear add-a-leaf springs with two N3 shock pairs. It fits only trucks with 3-inch wide rear leaf springs, so measure yours before ordering.
This 2.5-inch lift kit for the 1970–1976 Ford F-100 4WD (and 1976 F-150 4WD) raises ride height front and rear to even out factory rake. The front side supplies lifted coil springs, 4-degree C-bushings, a track bar bracket, and hardware; the rear side uses add-a-leaf springs with hardware, and two N3 nitrogen-charged shock pairs handle damping. Clearance supports tires up to 33 inches, though several 33-inch wheel and tire combinations in the fitment data are flagged for trimming. Confirm the 3-inch wide rear leaf spring requirement first. Listed install time is 5-7 hours. Shipping weight: 98.72 lb.
