The Rancho RS7MT RS77370 Suspension Shock Absorber is engineered to enhance both on-road comfort and off-road durability. Featuring a 2-inch monotube body filled with all-weather fluid, it ensures consistent performance across a wide temperature range. The shock’s full-floating piston and high-pressure nitrogen gas design work together to reduce aeration and prevent performance fade. Equipped with a 14mm hardened chrome piston rod, it offers increased resistance to scuffs and corrosion, contributing to its longevity. The RS77370 is designed for straightforward installation, arriving ready to mount without the need for additional components. Its satin black finish with the iconic Rancho red lettering adds a sleek appearance to your vehicle. This shock absorber is compatible with select Chevrolet, GMC, and Hummer models, including the Chevrolet Silverado 1500, GMC Sierra 1500, and Hummer H2.
