Rancho Shock Absorber RS5000X (MPN: RS55380)

Advanced nitrogen gas charged shock for enhanced vehicle performance and control.

The Rancho Shock Absorber RS5000X features a patented rebound valving system that significantly improves vehicle handling both on and off-road. This shock absorber is designed with a tuned compression control valve that harmonizes the shock's motion with the vehicle's dynamics, ensuring stability and control across various terrains. The enlarged 2-1/4 inch twin tube body increases fluid capacity, allowing for cooler operation and enhanced performance at different speeds.

Gas pressurization minimizes air-to-oil mixture, reducing the risk of foaming and shock fade, while providing a slight boost in spring rate. The 16 millimeter nitro-carburized rod enhances durability against scuffing and corrosion, contributing to the shock's longevity. With a full-displaced 35 millimeter bore and a 1-3/8 inch diameter sintered iron piston, this shock absorber offers heightened control and responsiveness to changing road conditions.

Features
