Rancho RS5000X 0″ Rear Lift Shocks for 1964-1969 GMC G-1500

Part Number: RS55118

Summary: The Rancho RS5000X series leverages advanced Cross-Tuned technology to provide a significant upgrade over factory damping for your classic vehicle. These twin-tube gas-pressurized shocks are engineered to handle the unique demands of both daily driving and light utility work, offering a balanced ride that minimizes harshness. By utilizing a larger 2.25-inch reserve tube, the RS5000X ensures greater oil capacity and cooler operation during extended use, delivering consistent performance and improved wheel control for your rear suspension.

Features

• Cross-Tuned Technology: A unique valve base system provides progressive engagement at varying speeds to ensure a smooth ride on-road and controlled damping off-road.
• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in oil foaming and aeration to ensure consistent performance under load.
• 2.25-inch Body Diameter: An increased fluid capacity provides better heat dissipation to ensure fade-free operation during heavy hauling or towing.
• All-Weather Fluid: Specialized synthetic oil contains friction modifiers to ensure smooth piston rod travel and reduced internal wear in extreme temperatures.
