About this kit
M1 Monotube Front Shocks, fitment-checked
Rough Country 770857_A is a front M1 monotube shock pair for 1999–2007 Chevrolet and GMC 1500 RWD trucks, including Silverado 1500 HD and the 2007 Classic bodies. Each shock uses a 2-inch seamless extruded tube with a 46mm digressive piston and an 18mm chromed rod. Carries a 3 Year Limited Warranty.
These M1 monotube front shocks fit 1999–2007 Silverado 1500 and Sierra 1500 RWD applications, plus the C1500, 1500 HD, and Classic variants listed in the fitment section. The monotube body and digressive valving handle changing surface conditions without fade, and the deflective-disc design sets rebound and compression on its own. The 18mm rod is case-hardened, chromed, and polished, and the zinc-plated body and vulcanized rubber bushings hold up to road spray and grit. Rough Country lists the install at 1-2 hours. One pair ships per box, so order a second set if you also plan to replace the rear.
