About this kit
M1R Monotube Rear Shocks, fitment-checked
Rough Country 770738RES_B is a pair of M1R monotube rear shocks with external reservoirs, sold as one kit containing a single M1R monotube reservoir shock pair. Fitment covers the 2002-2006 Chevrolet Avalanche 1500 in 4WD and RWD form, plus GMC Suburban applications from 1970-1974 and 1975-1978. Rough Country lists an install time of 1-2 hours. Warranty: 3 Year Limited Warranty.
These M1R monotube rear shocks fit the 2002-2006 Chevrolet Avalanche 1500 in both 4WD and RWD, along with GMC C15/C1500 and K15/K1500 Suburban models across the 1970-1974 and 1975-1978 ranges — check the fitment list for your submodel. The 46mm monotube body pairs a 2-inch digressive piston with a remote reservoir and an internal floating piston, so damping stays consistent as heat builds. The 16mm hardened, chromed rod, zinc-plated finish, and vulcanized rubber bushings handle the exposure that rear shocks live with. Rough Country lists 1-2 hours for the job.
