M1 Monotube Rear Shock

The Rough Country M1 Monotube Rear Shocks are engineered to provide exceptional ride quality and performance for your truck, whether on tough terrain or city streets. These shocks feature a 46mm monotube design with an internal floating piston that keeps oil and nitrogen separate, ensuring rapid response and eliminating cavitation for optimal vibration damping. Constructed with a durable steel body that is brushed and galvanized, these shocks are built to withstand harsh elements. Key internal components include a 46mm digressive piston for optimized compression and a 18mm centerless-ground, case-hardened, chromed, and super-polished rod. The digressive valving allows the shocks to instantly react to changing surface conditions, while the vulcanized natural rubber bushings provide durability. Installation is estimated to take 1-2 hours, and the shocks are sold in pairs. They come with a 3-year manufacturer's warranty. They are available for a range of Chevrolet Silverado and GMC Sierra 2500HD/3500HD models from 1999-2024, with specific fitment including 2WD and 4WD configurations across various model years.
