Smooth out every mile with the Rancho RS5000X shock absorber RS55371, a front-position damper that drops into the 1999-2006 Chevrolet Silverado 1500 and GMC Sierra 1500, 2000-2006 Chevrolet Tahoe, Suburban 1500, GMC Yukon and Yukon XL 1500, 2002-2006 Chevrolet Avalanche 1500, and 2007 Chevrolet Silverado 1500 Classic and GMC Sierra 1500 Classic. See the Buyer's Guide tab for the full application list.
Built around Rancho's exclusive Cross Tuned technology — a rebound valving system paired with an advanced compression phase — the RS5000X is designed for on- and off-road handling and performance.
- Progressive Engagement Valving: custom-tuned per vehicle to help reduce initial low-speed impacts and minimize a rough ride.
- 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.
- Handles temperature swings: large twin-tube body filled with all-weather fluid, rated to withstand internal temperatures from -40 to 248°F.
- Reduces fade: nitrogen gas pressurized to 150 PSI to minimize air-to-oil mixing, foaming, and damping fade.
A low-friction self-lubricating seal, polyurethane rebound bumper, rubber bushings, and fluon-banded piston round out the design. Backed by Rancho's Limited Lifetime Warranty. Sold individually; replace both front shocks together for balanced damping.
