Rancho 07-13 Chevrolet Avalanche Rear RS5000X Shock

This is the Rancho RS5000X rear shock absorber, part number RS55262, designed to fit a wide range of trucks and SUVs including the 2007-2013 Chevrolet Avalanche, as well as many Silverado, Suburban, Tahoe, and GMC Yukon models. If you're looking to improve your vehicle's on- and off-road handling, this shock absorber is built to help you get there.

Rancho built these RS5000X shocks with a unique valving system and an advanced compression phase to give you better control. The large twin-tube body is filled with all-weather fluid, which helps keep things cool even when temperatures get extreme, allowing for better vehicle control and resistance to internal temperatures from -40 to 248°F. You'll also find a 16mm nitro-carburized piston rod that's tough against scuffs and corrosion, plus double-welded loops at stress points for added durability. Inside, a 35mm sintered iron piston adds structural integrity, and a fluon-banded piston enhances responsiveness to road changes for a smoother ride. The Progressive Engagement Valving is custom-tuned for each application to reduce initial impacts at low speeds, minimizing a rough ride.

To help keep your ride consistent, these shocks are nitrogen gas pressurized to 150 PSI, which helps reduce foaming and damping performance fade. A polyurethane rebound bumper and rubber bushings work to absorb harshness, while the custom-tuned Compression Control Valve manages fluid transfer to absorb impacts without disc flutter, maintaining shock motion control. Rancho backs these shocks with a Limited Lifetime Warranty, so you can install them with confidence.
