About this kit
M1 Monotube Rear Shocks, fitment-checked
Rough Country 770791_A is a rear shock pair from the M1 monotube line, fitted to 1999–2004 Ford F-250 and F-350 applications including Super Duty 4WD and RWD trims. The 46mm monotube body uses digressive valving with self-adjusting deflective-disc rebound and compression control. Sold in pairs, so one order covers both rear corners. Carries a 3 Year Limited Warranty.
These M1 monotube rear shocks cover 1999–2004 Ford F-250 and F-350 trucks, spanning XL, XLT, Lariat, King Ranch, and Harley-Davidson Edition submodels in 4WD, plus F-350 RWD applications listed in the fitment section. Construction is a 2-inch seamless extruded tube around a 46mm digressive piston, with an 18mm centerless-ground, case-hardened and chromed rod, vulcanized natural rubber bushings, and a zinc-plated finish. The kit ships as one M1 monotube shock pair. Rough Country lists installation at 1-2 hours, so plan a short driveway session for the rear axle.
