Product Description

The Rancho RS55380 RS5000X Rear Shock Absorber is engineered to enhance rear suspension performance for lifted Chevrolet and GMC trucks with rear lift heights from about 1.0" to 2.5". Featuring Rancho's Progressive Engagement Valving and Tuned Compression Control Valve, this gas-charged, twin-tube rear shock smooths out road irregularities and helps maintain stability and ride comfort in both on- and off-road driving conditions. Its larger twin-tube body with all-weather fluid assists with heat management while providing consistent damping performance.

Built to last, the RS5000X includes a nitro-carburized piston rod for corrosion resistance, a protective dust boot to shield internal components, and rubber bushings to reduce noise and vibration. Designed as a direct-fit replacement for rear suspension applications on lifted Chevy and GMC trucks, RS55380 combines durability and performance for daily driving and trail use. Always verify exact fitment for your specific model, year, and lift configuration before installation.
