Smooth out the ride and keep your Jeep planted on- and off-road with the Rancho RS5000X Suspension Shock Absorber RS55255, a front shock that drops in as a direct-fit replacement for the 1997-2006 Jeep TJ and 1997-2006 Jeep Wrangler (see the Buyer's Guide tab for engine-level fitment). At its core is Rancho's exclusive Cross Tuned technology — a rebound valving system and advanced compression phase built to improve overall handling and performance in both settings.
Cross Tuned handling: Progressive Engagement Valving is custom-tuned per vehicle to help soften low-speed initial impacts and reduce a rough ride.
Strong and durable: 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.
Temperature ready: Large twin-tube body filled with all-weather fluid runs cooler and withstands internal temperatures of -40 to 248°F.
Reduces fade: Nitrogen gas pressurized to 150 PSI minimizes air-to-oil mixing to limit damping fade and foaming.
A polyurethane rebound bumper, rubber bushings, and a fluon-banded piston help absorb harshness for a smoother ride, and it's backed by Rancho's Limited Lifetime Warranty.
