About this kit
M1 Monotube Rear Shocks, fitment-checked
A pair of Rough Country M1 monotube rear shocks (770855_A) for 2022–2025 Toyota Tundra 4WD and RWD models. The 46mm monotube body uses a digressive piston with self-adjusting deflective-disc rebound and compression damping, and the assembly ships as a pair — one kit covers both rear corners.
These M1 monotube rear shocks fit the 2022–2025 Toyota Tundra in 4WD and RWD form, covering SR, SR5, Limited, Platinum, 1794 Edition, Capstone, and TRD Pro applications listed in the fitment section. The 2-inch seamless extruded tube houses a 46mm digressive piston, and the 18mm rod is centerless-ground, case-hardened, chromed, and polished. Vulcanized natural rubber bushings handle the mounting ends, and the body is zinc plated against road spray and salt. Rough Country lists an install time of 1-2 hours for the pair. Carries a 3 Year Limited Warranty.
