About this kit

M1 Monotube Rear Shocks, fitment-checked

Rough Country 770738_P is a pair of M1 monotube rear shocks for the 2023-2026 Chevrolet Colorado and GMC Canyon in 4WD or RWD. The kit ships as one M1 monotube shock pair, so both rear corners are covered in a single order. Estimated install time is 1-2 hours. Covered by a 3 Year Limited Warranty.

These M1 monotube rear shocks fit the 2023-2026 Chevrolet Colorado and GMC Canyon in both 4WD and RWD form, spanning WT, LT, Z71, Trail Boss and ZR2 on the Colorado side and Elevation, AT4, AT4X and Denali on the Canyon. The M1 body uses a 2-inch seamless extruded tube around a 46mm digressive piston with a self-adjusting deflective-disc design, riding on an 18mm case-hardened chromed rod with vulcanized natural rubber bushings. Zinc plating handles road spray and salt. Plan roughly 1-2 hours for the rear pair. Shipping weight: 13.01 lb.
