Part Number: RS55115

Summary: The Rancho RS5000X series delivers a sophisticated twin-tube gas pressurized design specifically engineered for the 1977-1979 Ford F-100 and F-150 4WD. This shock features the innovative CrossTun™ Technology, which utilizes a unique valve base system to provide a smooth, controlled ride over varying terrain. By reducing internal fluid aeration, these shocks ensure consistent damping performance and durability for daily driving and light off-road use.

Features

• CrossTun™ Technology: A specialized valve base design provides progressive engagement to ensure a smooth ride on-road and controlled damping off-road.
• Gas Pressurized Twin-Tube: Low-pressure nitrogen gas charge reduces fluid aeration and foaming to ensure consistent performance under high-cycle conditions.
• Protective Boot: A durable poly-vinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against debris.
