Chevrolet Avalanche 2500 Coilover Suspension Kit - Rear - Rancho - RS9000XL - `02-`06. This rear coilover kit pairs Rancho RS9000XL adjustable shocks with hardware tailored for 2002–2006 Avalanche 2500 models, offering tunable damping for drivers who want improved control and ride quality.

The RS9000XL design provides nine levels of adjustment through an easy-to-use external knob, letting you dial in firmness for both street driving and off-road use. The fourth-generation RS9000XL features integrated bottom mounts for added strength and a dual-component 2K paint finish to resist chips. A tri-tube body (application specific) and all-weather hydraulic fluid allow operation across a wide temperature range. Low-friction, self-lubricating seals, polyurethane rebound bumpers and graphite-filled pistons help deliver consistent response, reduced fade from nitrogen pressurization, and extended service life. This kit is appropriate for stock or lifted trucks that see towing, hauling, or off-road duty, and it comes with Rancho’s Limited Lifetime Warranty.
