Fabtech FTS7358 Performance Passenger Side Twin-Tube Shock Absorber for 2500-2020 Compatible with/Replacement for Chevy Silverado

Fabtech performance shocks have been designed to work in conjunction with each of our suspension systems, resulting in superior ride control. Features include high velocity 9-stage valving for excellent dampening capabilities and a closed cell insert to reduce shock fade at high speeds. A twin tube shock absorber consists of a thin wall inner pressure tube and outer reserve tube. The inner tube houses the valving components, piston and base valve, and is where the damping forces are generated. The outer tube acts as a reservoir for displaced fluid from the shaft volume during the compression stroke. Also contained in the outer tube is a foam sleeve or gas bag that contracts and expands with respect to shaft displacement to eliminate air pockets and increase the performance of the shock.
