A pair of M1R monotube rear shocks for the 2015-2022 Chevrolet Colorado and GMC Canyon in 4WD or RWD trim (Rough Country 770738RES_E). Each shock uses a 46mm monotube body with a remote external reservoir and an internal floating piston to keep damping consistent as heat builds. The box holds one M1R monotube reservoir shock pair. Estimated install time is 1-2 hours.
These M1R monotube rear shocks fit the 2015-2022 Chevrolet Colorado and GMC Canyon in both 4WD and RWD, covering the submodel list shown in the fitment section — Base, LT, WT and Z71 on the Colorado, and AT4 through SLT on the Canyon. The 2-inch seamless extruded body carries a 2-inch digressive piston with independently self-adjusting rebound and compression, riding on a 16mm case-hardened chromed rod. Zinc plating and vulcanized natural rubber bushings handle the weather and impact side of the job. Rear application only; pair with matching front units. Carries a 3 Year Limited Warranty.
