About this kit
M1 Monotube Front Shocks, fitment-checked
Rough Country 770766_E is a front shock pair from the M1 monotube line, built for 1999-2007 Chevrolet and GMC 1500 RWD trucks. The pair uses a 46mm digressive piston and an 18mm chromed, case-hardened rod inside a 2-inch seamless extruded tube. Sold in pairs, so one order covers both front corners. Carries a 3 Year Limited Warranty.
These M1 monotube front shocks fit 1999-2007 Chevrolet and GMC 1500 RWD applications, including Silverado 1500 and Sierra 1500 from 1999-2006, the 2007 Classic body styles, and the 1500 HD trims listed in the fitment section. Chevrolet C1500 RWD models from 1999-2000 are covered as well. The monotube body resists fade during longer runs, and the digressive valving reacts as the surface changes. Deflective-disc damping self-adjusts through rebound and compression, and vulcanized natural rubber bushings handle the mounting ends. Rough Country lists installation at 1-2 hours. Confirm your submodel against the fitment table before ordering.
