Product Description

The Rancho RS55378 RS5000X Front Shock Absorber is built for lifted heavy-duty Chevrolet and GMC trucks with front suspension lifts of about 1.0-2.5". Its gas-charged twin-tube design, Progressive Engagement Valving, and tuned compression control valve help absorb bumps and maintain control over mixed road conditions. RS5000X shocks combine enhanced handling with everyday comfort for lifted trucks.

Featuring a robust 2.25" shock body with all-weather fluid and a nitro-carburized piston rod for corrosion resistance, this shock is designed for durability and consistent performance. Protective dust boots and rubber bushings reduce noise and protect internal components. Check fitment for your specific heavy-duty model and lift setup before installation.
