Product Description

The Bilstein 24-060820 B6 4600 Series Rear Shock is a performance-oriented direct-fit replacement engineered for the rear suspension of full-size Chevrolet and GMC pickup trucks from 1999 through 2010 when equipped with factory stock ride height. Designed with a velocity-sensitive monotube gas-pressure piston and digressive valving, this rear shock delivers consistent damping control that adapts to changing road and load conditions, providing improved ride quality, stability, and handling compared to worn original shocks.

Built to handle heavy loads, towing, and daily driving duties, the B6 4600 Series rear shock enhances chassis control while maintaining comfortable ride characteristics. Its robust yellow painted body and protective blue boot ensure long-lasting performance even under demanding use. Installation is simple via direct OE-style mounting points, making this shock a dependable upgrade for owners replacing factory rear shocks on Silverado and Sierra 1500 HD, 2500, and 2500 HD trucks across multiple model years at stock height. For balanced damping and optimal performance, it's recommended to replace shocks in pairs on the rear axle.
