Take Control Of Every Heavy Duty Adventure

A lifted HD truck should feel confident every time you hit the road, and the Bilstein 24-218030 B8 5100 Rear Shock is built to make that happen. Designed for 2011-2026 Chevrolet Silverado 2500HD, 3500HD, GMC Sierra 2500HD, and 3500HD models with 3 to 4 inches of rear lift, this shock delivers the control and comfort that factory shocks often struggle to maintain. Whether your truck spends its weekends pulling a trailer or tackling rough backroads, you will notice a more planted and predictable ride. Additionally, the Bilstein monotube design keeps damping performance consistent even when the shock is working hard over long distances or uneven terrain. The result is improved stability through corners, reduced suspension bounce, and better confidence behind the wheel. Its durable zinc-plated finish also helps protect against corrosion, making it a dependable upgrade for trucks that see mud, rain, snow, or salted roads. When you want your suspension to perform as well as the rest of your truck, this is an upgrade you will appreciate every mile.

Precision Tuned To Support Your Lifted Suspension

The Bilstein B8 5100 Rear Shock is engineered specifically for trucks equipped with 3 to 4 inches of rear lift, ensuring the suspension geometry works as intended. A 46mm high-flow monotube piston provides fast, consistent damping while efficiently dissipating heat to reduce performance loss during demanding driving conditions. Furthermore, Bilstein's velocity-sensitive digressive valving automatically responds to changing suspension movement, delivering excellent control over small road imperfections as well as larger impacts. This application-specific tuning helps improve handling, towing stability, and overall ride quality without requiring any manual adjustments. The smooth body, non-coilover construction offers a direct replacement design with eye-to-eye mounting points for compatible applications. A corrosion-resistant zinc-plated finish and included black bellows boot provide added protection from moisture, dirt, and road debris to help extend service life. Backed by Bilstein's limited lifetime warranty, this rear shock combines proven durability with the responsive performance that has made the 5100 Series a trusted choice for lifted heavy duty trucks.
