Smooth out the ride and add off-road control with the Rancho RS5000X Suspension Shock Absorber RS55328, a rear-position damper that drops in as a direct-fit replacement for the 2007-2017 Jeep Wrangler and the 2018 Jeep Wrangler JK. At its heart is Rancho's exclusive Cross Tuned technology — a rebound valving system paired with an advanced compression phase tuned to improve overall handling and performance on and off road.
- Cross Tuned + Progressive Engagement Valving: custom-tuned per vehicle to help reduce initial low-speed impacts and minimize a rough ride.
- Strong and durable: 16 mm nitro-carburized piston rod to resist scuffs and corrosion, double-welded loops at stress areas, a 35 mm sintered iron piston, and a polyvinyl protective boot.
- Handles temperature extremes: a 2 1/4-inch large twin-tube body filled with all-weather fluid for cooler operation, rated to withstand internal temperatures of -40 to 248°F.
- Reduces fade: nitrogen gas pressurized to 150 PSI to minimize air-to-oil mixing that causes damping fade and foaming.
A polyurethane rebound bumper, rubber bushings, and a fluon-banded piston help absorb harshness for a smoother ride, while a low-friction, self-lubricating seal retains gas and oil. Backed by Rancho's Limited Lifetime Warranty.
