About this kit
M1 Monotube Rear Shock Pair, fitment-checked
Rough Country 770826_I is a rear M1 monotube shock pair for 1970–1976 Ford F-100 4WD and 1976–1979 Ford F-150 4WD models. The order covers both sides — one pair per box. Built on a 2-inch extruded tube with a 46mm digressive piston and an 18mm chromed rod, and covered by 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, spanning Base, Custom, Northland, Ranger, Ranger Lariat, Ranger XLT, and XLT submodels listed in the fitment section. The 46mm monotube body uses digressive valving that reacts as the surface changes, with self-adjusting deflective-disc rebound and compression control. Bodies are zinc plated and ride on vulcanized natural rubber bushings. Rear shock swaps on these trucks are listed at 1-2 hours; check both mount ends against the stud-and-loop configuration shown in the photos before you start.
