Soak up rough trails and firm up on-road handling with the Rancho RS5000X Suspension Shock Absorber RS55063, a front shock that drops in as a direct-fit replacement for the 2020-2025 Jeep Gladiator and 2018-2025 Jeep Wrangler (see the Buyer's Guide tab for engine-level fitment). It's built around Rancho's Cross Tuned technology — an exclusive rebound valving system and advanced compression phase tuned to improve overall handling and performance on and off road.
- Custom-tuned valving: Exclusive Progressive Engagement Valving helps reduce initial impacts at low speeds to minimize a rough ride, while the Compression Control Valve regulates fluid transfer to help maintain shock motion control.
- Strong and durable: 16mm nitro-carburized piston rod resists scuffs and corrosion, with double-welded loops at stress areas, a 35mm sintered iron piston, and a polyvinyl protective boot.
- Extreme-temperature ready: Large twin-tube body filled with all-weather fluid for cooler operation and rated to withstand internal temperatures of -40 to 248°F.
- Smooth, fade-resistant: Polyurethane rebound bumper, rubber bushings, and a fluon-banded piston smooth the ride; nitrogen gas pressurized to 150 PSI minimizes air-to-oil mixing to reduce damping fade and foaming.
