Keep your rear suspension composed on-road and off with the Rancho RS5000X Suspension Shock Absorber (RS55328), a rear-position shock absorber built around Rancho's exclusive Cross Tuned technology. It drops in as a direct-fit replacement for the 2007-2017 Jeep Wrangler and the 2018 Jeep Wrangler JK.
- Cross Tuned technology: pairs an exclusive rebound valving system with an advanced compression phase to improve overall handling and performance on and off road.
- Progressive Engagement Valving: custom-tuned for each vehicle to help reduce initial impacts at low speeds and minimize a rough ride.
- Strong, durable build: a 16 mm nitro-carburized piston rod resists scuffs and corrosion, with double-welded loops at stress areas, a 35 mm sintered-iron piston and a polyvinyl protective boot.
- All-weather performance: a large 2-1/4 inch twin-tube body filled with all-weather fluid runs cooler and withstands internal temperatures from -40 to 248°F.
Nitrogen gas pressurized to 150 PSI helps minimize air-to-oil mixing to reduce damping fade and foaming, while a polyurethane rebound bumper and rubber bushings help absorb harshness and a fluon-banded piston enhances responsiveness to changing road conditions for a smoother ride. A Compression Control Valve custom-tuned for each vehicle regulates fluid transfer, and a low-friction, self-lubricating seal retains gas and oil for quicker rebound. Sold individually; for balanced ride control, replace the rear shocks as a matched pair. Backed by Rancho's Limited Lifetime Warranty.
