RS5000X Shock Absorber

The Rancho RS5000X Shock Absorber (RS55118) is engineered to enhance both on- and off-road performance for a wide range of vehicles including Chevrolet, Dodge, Ford, GMC, International, Jeep, Mitsubishi, and Toyota. It utilizes Rancho's exclusive Cross Tuned technology, which integrates innovative rebound valving and advanced compression control to deliver superior performance and a smooth, controlled ride, making it an excellent choice for trucks, SUVs, and Jeeps. Key features include Progressive Engagement Valving to minimize rough ride impacts at low speeds, a durable 16mm nitro-carburized piston rod resistant to scuffs and corrosion, and double-welded loops at stress points for enhanced structural integrity. The shock is built with a large twin-tube design filled with all-weather fluid, capable of operating in extreme temperatures from -40°F to 248°F, ensuring cooler operation and consistent control. It also incorporates polyurethane rebound bumpers and rubber bushings to absorb harsh road impacts and improve ride quality. This passive suspension component is nitrogen gas-charged to 150 PSI, which helps prevent damping performance fade by minimizing air-to-oil mixture. The specifications include a 2.25-inch body diameter, a 14.01-inch compressed length, and a 22.29-inch extended length, with mounting hardware included. The shock absorber features a white painted finish and a steel cylinder construction. It is designed for vehicles with specific lift heights and suspension setups, and careful attention to fitment notes is recommended to ensure proper installation and function for each specific application, such as the mention of specific lift height requirements for Chevrolet Blazers and the note about lubrication and extra effort for installation on certain Dodge W100/W200 Series models from 1961-1971.
