Product Description
The BILSTEIN 24-185677 4600 Series Shock Absorber is a premium rear suspension upgrade for 2001-2010 Chevrolet Silverado and GMC Sierra 2500HD/3500HD 4WD trucks. Designed for stock height applications, this shock delivers improved ride quality, handling, and durability over worn factory shocks.
Built with Bilstein’s industry-leading 46mm monotube gas pressure design, the 4600 Series ensures consistent, fade-free performance even under heavy towing, hauling, and demanding road conditions.

The velocity-sensitive digressive piston reacts instantly to changing road surfaces, providing a smooth, controlled ride during daily driving while maintaining stability under load. Whether you're towing a trailer or commuting, this shock helps keep your Duramax truck planted and predictable.
