Rancho Suspension RS55005 RS5000X Gas Shock Absorber

The Rancho RS5000X RS55005 shock absorber delivers enhanced on-road comfort and off-road capability through advanced damping technology. Featuring Rancho's exclusive Progressive Engagement Valving system, this shock automatically adjusts to changing road conditions, providing firm control during aggressive driving while maintaining a comfortable ride during normal cruising.

Key Features:

• 10-stage velocity-sensitive valving adapts to varying terrain and load conditions
• Large 2-inch bore diameter increases fluid capacity for improved heat dissipation and fade resistance
• Premium all-weather fluid maintains consistent performance across temperature extremes
• Polyurethane bushings and protective boot included for extended service life
• Low-friction, self-lubricating seal design reduces wear and extends shock longevity
• Twin-tube construction with sintered iron piston for durability
• Nitrogen gas-charged to minimize aeration and foaming

The RS5000X series represents Rancho's most advanced single-shock solution, engineered for trucks, SUVs, and Jeeps that see mixed-use duty. The progressive valving technology allows the shock to firm up during compression cycles when encountering rough terrain or heavy loads, while remaining compliant during lighter driving conditions. This results in improved vehicle control, reduced body roll, and better tire contact with the road surface.

Backed by Rancho's limited lifetime warranty, the RS55005 is designed and tested to exceed OE specifications while providing enhanced performance characteristics. Direct bolt-on installation using factory mounting points makes upgrade straightforward without modifications.
