Product Description

The Rancho RS55379 RS5000X Rear Shock Absorber is engineered to upgrade rear suspension dynamics on heavy-duty Chevrolet and GMC trucks with stock or slightly raised rear heights up to approximately 2.5". Featuring Rancho's trademark Progressive Engagement Valving and Tuned Compression Control Valve, this gas-charged twin-tube shock helps smooth out bumps and maintain vehicle control over mixed highway and off-road conditions.

Built for durability, RS55379 incorporates a nitro-carburized piston rod, enlarged twin-tube body, and protective dust boot to extend service life, while rubber bushings help absorb vibration and reduce noise. Designed as a direct rear shock replacement for select Chevy Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD models from 2011 through 2025, this shock delivers balanced performance for daily driving and performance use. Always confirm exact fitment for your specific trim and configuration before ordering.
