Part Number: RS55116

Summary: The Rancho RS5000X Series gas-pressurized shocks are engineered to provide a significant upgrade in ride quality for your heavy-duty workhorse. Featuring a sophisticated twin-tube design, these shocks utilize a unique Cross Tuning base valve system to balance off-road durability with smooth street manners. By minimizing fluid aeration and shock fade, the RS5000X ensures consistent damping performance under heavy loads and demanding towing cycles.

Features

• Cross Tuning Technology: A specialized progressive rebound and compression valve system provides custom-tuned damping to ensure controlled handling on varied terrain.
• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in oil foaming and aeration to ensure consistent performance during rapid cycling.
• Twin-Tube Body: A 2.25-inch diameter reserve tube provides increased oil capacity and dent resistance to ensure long-term durability in harsh environments.
• Protective Boot: Included polyvinyl accordion boot provides a physical barrier for the piston rod to ensure the seal remains free from debris and rock chips.
