Product Description

The **Rancho RS55111** is a gas-charged shock absorber in the RS5000X™ series engineered to provide a balance of on- and off-road ride quality and suspension control for a variety of applications. Featuring Rancho's Progressive Engagement valving and an advanced compression phase, this shock helps smooth out initial bumps and rough surfaces while maintaining stable damping through the travel cycle. Its larger twin-tube body filled with all-weather fluid helps maintain performance across temperature extremes and prolonged use.

Equipped with a nitro-carburized piston rod and protective boot, the RS55111 offers enhanced durability and resistance against corrosion and debris. Rubber bushings and a polyurethane rebound bumper help absorb harsh impacts, improving overall ride comfort. Designed as a direct-fit replacement in compatible applications, this shock is suitable for restored classics or off-road conversions where RS5000X series performance is desired. Always verify specific vehicle fitment before ordering, as this part serves multiple suspension setups and may vary by model.
