Rancho RS5000X Front Shock Absorber RS55295 - Select 1999-2013 Chevrolet & GMC

Fits select 1999-2013 Chevrolet and GMC vehicles, including Silverado/Sierra 1500 HD, 2500, 2500 HD, 3500 HD, and Suburban/Yukon XL 2500. This heavy-duty front shock absorber is engineered to improve handling and performance for work and off-road applications.

The Rancho RS5000X series features a unique Cross Tuned technology that utilizes a progressive engagement valving system. This design helps minimize initial impacts at low speeds while maintaining firm control during aggressive driving or when hauling heavy loads. The large twin-tube body is filled with all-weather fluid, allowing the shock to maintain consistent damping performance in extreme temperatures ranging from -40 to 248°F.
