Rancho RS5000X 0-2″ Rear Lift Shocks for 1977-1986 GMC K3500 4WD

Part Number: RS55132

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for your GMC K3500. Featuring a cross-tuned twin-tube design, these shocks utilize a unique valving system that minimizes foam and cavitation during off-road use while maintaining smooth street comfort. Configured for 0-2 inches of rear lift, they offer the perfect balance of rugged performance and daily drivability for classic 4WD heavy-duty trucks.

Features

• Cross-Tuned Technology: A specialized progressive valving system provides improved handling and control to ensure stability during both high-speed maneuvers and low-speed crawling.
• Gas Pressurization: High-pressure nitrogen gas charging provides consistent damping performance to ensure reduced aeration and shock fade.
• Heavy-Duty Construction: A 2.25-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures and a longer service life.
• Protective Boot: A red polyvinyl accordion boot provides a shield for the shock rod to ensure protection against rocks, dirt, and debris.
