Part Number: RS55113

Summary: The Rancho RS5000X series leverages advanced CrossTune technology to provide a significant upgrade over factory damping for your classic GMC C2500. Designed as a gas-pressurized twin-tube shock, it features a unique progressive engagement valving system that minimizes harshness during initial impacts. This shock is specifically engineered for 2WD models with rear coil springs, ensuring a smooth, controlled ride for both daily driving and light hauling.

Features

• CrossTune Technology: A unique valving system provides a progressive engagement curve to ensure consistent comfort across varying road surfaces.
