About this kit

M1 Monotube Rear Shocks, fitment-checked

Rough Country 770740_J is a pair of M1 monotube rear shocks for 1970-1976 Ford F-100 4WD and 1976-1979 Ford F-150 4WD trucks. The 46mm monotube body uses a digressive piston with self-adjusting rebound and compression control, and the kit ships as one shock pair. Carries a 3 Year Limited Warranty.

These M1 monotube rear shocks fit 1970-1976 Ford F-100 4WD and 1976-1979 Ford F-150 4WD trucks across Base, Custom, Northland, Ranger, Ranger XLT, Ranger Lariat, and XLT submodels listed in the fitment section. The 2-inch seamless extruded body houses a 46mm digressive piston valved to react as the surface changes, riding on an 18mm case-hardened, chromed, and polished rod. Vulcanized natural rubber bushings and a zinc-plated finish handle road salt and grit. Rough Country lists installation at 1-2 hours for the pair. Check your rear mount style against the shock ends before ordering.
