Rear Shock Absorber for 1988-1999 Chevrolet C1500 & More - Rancho RS55190

Help your truck handle better on and off road with the Rancho shock absorber RS55190, a rear RS5000X suspension shock built around Rancho's exclusive Cross Tuned technology. It fits many vehicles, among them the 1988-1999 Chevrolet C1500, 1988-1999 Chevrolet K1500 and 1995-2000 Chevrolet Tahoe. See the Buyer's Guide tab for the full list.

• Cross Tuned technology: Pairs an exclusive rebound valving system with an advanced compression phase, designed to improve overall handling and performance on and off road.
• Progressive Engagement Valving: Custom-tuned for each vehicle to help reduce initial impacts at low speeds and minimize a rough ride.
• Strong and durable: A 16mm nitro-carburized piston rod resists scuffs and corrosion. Loops are double-welded at stress areas, a 35mm sintered iron piston adds structural integrity, and a polyvinyl protective boot is included in the design.
• Temperature and fade control: A large 2-1/4-inch twin-tube body filled with all-weather fluid allows cooler operation and gives the shock the ability to withstand internal temperatures of -40 to 248°F. Nitrogen gas pressurized to 150 PSI minimizes air-to-oil mixing to reduce damping fade and foaming.

A Compression Control Valve, custom-tuned for each vehicle, regulates fluid transfer to absorb impacts without disc flutter and help maintain shock motion control. The application-specific piston has an expanded area for more control of shock motion, and its fluon band helps it respond to changing road conditions. A low-friction, self-lubricating seal retains gas and oil. A polyurethane rebound bumper and rubber bushings help absorb ride harshness. Replacing both rear shocks together is recommended for even, balanced handling. This Rancho absorber is backed by Rancho's Limited Lifetime Warranty.
