Product Description

The Rancho RS55325 RS5000X Rear Shock Absorber is a performance rear suspension shock designed for 2004-2012 Chevrolet Colorado and GMC Canyon trucks in both 2-wheel drive and 4-wheel drive configurations. Part of Rancho's RS5000X series, this shock features gas pressurization and progressive engagement valving that deliver improved damping control and ride quality over factory shocks. The 16 mm nitro-carburized piston rod and full-displaced piston bore enhance durability and consistent performance under on- and off-road driving conditions.

Built for drivers seeking a dependable shock upgrade, the RS55325 is suitable for stock ride height vehicles and can also support lifted trucks when used with compatible lift kits that maintain proper driveshaft clearance and suspension geometry. Its protective boot helps extend service life by shielding the shaft from dirt and debris, while the rubber bushings reduce noise and vibration for a smoother overall ride. Always verify vehicle suspension setup and lift compatibility before installation.
