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

Part Number: RS55120

Summary: The Rancho RS5000X series leverages a cross-tuned twin-tube design to provide a significant upgrade over factory damping for your classic GMC C3500. By utilizing a unique progressive engagement valving system, these shocks provide a smooth street ride while maintaining the durability needed for heavy-duty work. Designed specifically for vehicles at stock ride height, they ensure consistent tire-to-road contact and reduced body roll without compromising comfort.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition between low and high-speed damping to ensure a controlled ride on varied road surfaces.
• Twin-Tube Gas Pressure: The large 2.25-inch body holds increased fluid capacity to provide cooler operating temperatures and ensure fade-free performance during extended towing or hauling.
• Nitro-Carburized Piston Rod: A 16mm heavy-duty rod construction provides superior scuff and corrosion resistance to ensure long-term seal integrity in harsh environments.
• Protective Boot Included: High-quality polyvinyl bellows provide a physical barrier for the shock rod to ensure debris does not damage the internal seals.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks are configured for 0-inch lift heights and are designed to replace factory-length dampers. They do not provide any lift on their own.

What is the benefit of the RS5000X gas pressurization?
The low-pressure nitrogen gas charge reduces aeration (foaming) of the shock oil, which prevents the “fading” feeling during heavy use or bumpy roads.

Do these include the mounting hardware?
Yes, these shocks come with the necessary bushings and boots. You will typically reuse your factory mounting bolts during installation.
