Rancho RS5000X 0″ Rear Lift Shocks for 1984-1991 Jeep Grand Wagoneer SJ 4WD

Part Number: RS55113

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality for the Jeep Grand Wagoneer SJ. Utilizing a sophisticated twin-tube design with a unique Cross-Tuned valve system, these shocks provide a smooth, controlled ride on the street while maintaining enough damping force for light off-road use. By minimizing internal fluid cavitation, these gas-pressurized shocks ensure consistent performance and durability for classic 4WD applications.

Features

• Cross-Tuned Technology: A progressive engagement valve system provides a smooth transition between low and high-speed impacts to ensure maximum comfort on varied terrain.
• Nitro-Carburized Piston Rod: The 16mm heavy-duty rod provides superior corrosion resistance and structural integrity to ensure long-term seal life in harsh environments.
• Gas Pressurization: High-pressure nitrogen charging provides reduced aeration and foaming to ensure consistent damping performance during repetitive cycling.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier against road debris to ensure the chrome-hardened rod remains free of nicks and scratches.
