Rancho RS5000X 0″ Rear Lift Shocks for 1967-1972 GMC C3500 2WD

Part Number: RS55118

Summary: The Rancho RS5000X series leverages a unique CrossTune Technology system to provide a significant upgrade over factory damping for your GMC C3500. Designed as a twin-tube gas pressurized shock, it balances daily driving comfort with the rugged durability required for heavy-duty leaf spring applications. This configuration is specifically valved to mitigate harsh impacts while maintaining a smooth, controlled ride at stock ride height.

Features

• CrossTune Technology: A unique progressive rebounding valving system provides a custom-tuned ride for leaf spring vehicles to ensure consistent control across varying terrains.
• Twin-Tube Design: A 2.25-inch diameter outer tube provides increased oil capacity and dent resistance to ensure long-term cooling and structural integrity.
• Nitrogen Gas Pressurization: A high-pressure gas charge provides a barrier against oil foaming to ensure fade-free performance during sustained hauling or towing.
• 16mm Nitro-Carburized Rod: A heavy-duty hardened piston rod provides superior scuff resistance and protection against corrosion to ensure a long seal life.
