Rancho Shock Absorber (MPN: RS55843)

Advanced nitrogen gas charged strut for improved handling and performance.

The Rancho Shock Absorber is engineered to enhance both on-road and off-road vehicle performance through its innovative valving system. Featuring cross-tuned technology, this shock absorber utilizes an exclusive rebound valving system and advanced compression phase to significantly improve handling and ride quality. The nitrogen gas charged design minimizes air-to-oil mixture, reducing damping performance fade and foaming, ensuring consistent performance under various conditions.

Constructed with a nitro-carburized piston rod, the Rancho Shock Absorber resists scuffs and corrosion, while the double-welded loops at stress areas provide enhanced structural integrity. The large twin tube body is filled with all-weather fluid, allowing for cooler operation and increased vehicle control, capable of withstanding extreme temperatures ranging from -40 to 248 degrees Fahrenheit. The polyurethane rebound bumper and rubber bushings work together to absorb ride harshness, contributing to a smoother driving experience.

This shock absorber is designed with a low-friction, self-lubricating seal that retains gas and oil for quicker rebound and smoother compression. The compression control valve is custom-tuned for each vehicle, regulating fluid transfer to absorb impacts effectively without compromising shock motion control. With its unique features and robust construction, the Rancho Shock Absorber is a reliable choice for those seeking to enhance their vehicle's performance.
