Rancho RS7MT Monotube Front Shock for Select 1999-2019 GM Trucks/SUVs & Hummer H2 - RS77370

Fits select 1999-2019 Chevrolet Silverado, Suburban, and Avalanche, GMC Sierra and Yukon XL (1500 HD through 3500 HD), and 2003-2009 Hummer H2.

Engineered for high-performance handling both on and off-road, the Rancho RS7MT monotube shock absorber is specifically designed to dissipate heat rapidly. This makes it an ideal upgrade for heavy-duty applications and vehicles equipped with larger wheel and tire packages. The RS77370 features a large 2-inch monotube body filled with all-weather fluid, allowing it to maintain consistent damping performance in extreme environments ranging from -40°F to 248°F.

Construction includes a 14mm hardened chrome piston rod for superior surface integrity and a 46mm fluon-banded piston for precise sealing. The internal high-pressure nitrogen gas charge maintains constant pressure against the hydraulic oil, virtually eliminating aeration and shock fade during aggressive use. The integrated dirt wiper sealing system provides an extra layer of defense, keeping moisture and debris away from the internal seals.
