Rear Shock Absorber for 2019-2025 Chevrolet Silverado 1500 & More - Rancho RS55100

Smooth out the ride and keep your truck planted with the Rancho RS5000X Suspension Shock Absorber (RS55100), a rear-position Rancho shock absorber built around Rancho's exclusive Cross Tuned technology. It's a direct-fit replacement for the 2019-2025 Chevrolet Silverado 1500, 2022 Chevrolet Silverado 1500 LTD, 2019-2025 GMC Sierra 1500, and 2022 GMC Sierra 1500 Limited — see the "Vehicles it fits" section for engine-level fitment.

• Cross Tuned technology: an exclusive rebound valving system and advanced compression phase designed to improve overall on- and off-road handling and performance.
• Progressive Engagement Valving: custom-tuned per vehicle to help reduce initial impacts at low speeds and minimize a rough ride.
• Strong and durable: 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.
• Extreme-temperature ready: a large twin-tube body filled with all-weather fluid for cooler operation, rated to withstand internal temperatures of -40 to 248°F.

A polyurethane rebound bumper and rubber bushings help absorb ride harshness, while nitrogen pressurized to 150 PSI helps minimize air-to-oil mixing to reduce damping fade and foaming. A low-friction, self-lubricating seal retains gas and oil for quicker rebound and smoother compression. Backed by Rancho's Limited Lifetime Warranty.
