Take on rutted trails and highway miles with the Rancho RS5000X Suspension Shock Absorber RS55329, a front-position damper built around Rancho's exclusive Cross Tuned technology, which pairs a rebound valving system with an advanced compression phase to improve overall on- and off-road handling. It installs as a direct-fit replacement for the 2007-2017 Jeep Wrangler and the 2018 Jeep Wrangler JK.
- Cross Tuned & Progressive Engagement Valving: Custom-tuned per vehicle to help reduce initial low-speed impacts and smooth out a rough ride.
- Strong, durable build: 16mm nitro-carburized piston rod that resists scuffs and corrosion, double-welded loops at stress areas, a 35mm sintered iron piston, and a polyvinyl protective boot.
- Handles temperature extremes: Large twin-tube body filled with all-weather fluid for cooler operation and control, rated to withstand internal temperatures of -40 to 248°F.
- Reduces fade: Nitrogen gas pressurized to 150 PSI to minimize the air-to-oil mixture 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.
