About this kit
2.5-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 530-70-7630 is a 2.5 inch lift kit for the 1970-1976 Ford F-100 4WD and the 1976 Ford F-150 4WD. Front lift comes from coil springs with 4-degree C-bushings and a track bar bracket; the rear uses replacement 4in lifted leaf springs with U-bolts. Two N3 shock pairs are included. It fits only trucks with 3-inch wide rear leaf springs.
This 2.5 inch lift kit for the 1970-1976 Ford F-100 4WD and 1976 Ford F-150 4WD pairs 2.5in front coils with new rear leaf springs that take the place of the factory rear block, so the truck sits closer to level front-to-rear. Confirm your rear springs measure 3 inches wide before ordering, since narrower springs are not supported. Rough Country lists 5-7 hours for the installation. Tire and wheel combinations up to 33 inches are covered in the fitment data, with a few of the listed wheel sizes calling for trimming.
