About this kit

M1R Monotube Rear Shocks, fitment-checked

A pair of Rough Country M1R monotube rear shocks for the 2002-2006 Chevrolet Avalanche 2500 in 4WD or RWD. The external-reservoir monotube design uses a 46mm body, a 2-inch digressive piston, and a 16mm chromed rod, with zinc-plated plating and vulcanized natural rubber bushings. Estimated install time is 1-2 hours.

These M1R monotube rear shocks fit the 2002-2006 Chevrolet Avalanche 2500 in both 4WD and RWD, covering Base, LS, and LT submodels listed in the fitment section. The box holds one M1R monotube reservoir shock pair, so plan on doing the rear axle in one sitting — Rough Country lists 1-2 hours for the job. The external reservoir and internal floating piston move heat away from the damping oil, while digressive valving handles changing surfaces. Shipping weight: 13.01 lb. Covered by a 3 Year Limited Warranty.
