However, 2WD and 4WD trucks have different coilover assembly lengths. The Ford F150 4WD models have a longer unit that will not fit into 2WD models. The Ford F150 2WD can installed on a 4WD truck but will not provide adequate lift and will bottom out incorrectly. Shocks can be converted from 2WD to 4WD or vice versa via lower rodend conversion.
