About this kit
M1 Monotube Rear Shocks, fitment-checked
Rough Country 770838_A is a pair of M1 monotube rear shocks for the 2007–2021 Toyota Tundra in 4WD and RWD. The pair ships together — order one unit to cover both rear corners. Build details include a 2-inch seamless extruded tube body, a 46mm digressive piston, and an 18mm chromed, case-hardened rod. Covered by a 3 Year Limited Warranty.
These M1 monotube rear shocks fit the 2007–2021 Toyota Tundra in 4WD and RWD across SR, SR5, Limited, Platinum, 1794 Edition, TRD Pro, Nightshade, Trail, and Base submodels shown in the fitment section. The kit is one M1 monotube shock pair, so a single order handles the rear axle. Digressive valving with self-adjusting deflective discs separates rebound from compression response, and the zinc-plated body and vulcanized natural rubber bushings handle exposure. Rough Country lists an install time of 1-2 hours. Confirm your rear shock mounting style before ordering, then plan the swap one side at a time.
