Add More Stability and Control on All Four Corners

A smooth, controlled ride is key to getting the most out of your 2011-2024 GM 2500HD or 3500HD, and the Bilstein B8 5100 Series Front & Rear Shock Kit delivers exactly that. Whether your truck sees heavy towing, off-road trails, or just daily highway miles, stock shocks can struggle to keep up—especially as they wear out over time. This complete front and rear shock kit replaces your factory setup with Bilstein’s performance-driven 5100 series, designed to improve handling, stability, and overall ride comfort. One of the biggest advantages of this kit is its ability to accommodate front-end leveling up to 1.5 inches. While these shocks won’t lift your truck on their own, they work seamlessly with torsion key leveling kits or mild front lifts to ensure proper suspension travel and damping. This means better control, a more balanced stance, and enough front-end clearance for larger tires—all without compromising ride quality. In the rear, the shocks are designed to handle up to 1 inch of lift, making them a perfect match for trucks with slightly taller rear springs or those looking to maintain proper suspension geometry after modifications.

Performance You Can Feel

Performance is where these Bilstein shocks really shine. Each shock features monotube gas pressure technology, providing consistent damping and eliminating fade under heavy loads or rough conditions. The 46mm digressive piston and self-adjusting deflective disc valving allow the shocks to instantly adapt to changing terrain, keeping your truck planted and predictable whether you’re towing a trailer, hauling heavy payloads, or hitting uneven backroads. Unlike factory shocks, which can feel sluggish and unresponsive, the Bilstein 5100s deliver firm yet controlled handling without sacrificing comfort.

Heavy-Duty Shock Bodies with Straightforward Install

The Bilstein B8 5100's are built with zinc-plated steel bodies and a multi-layer corrosion-resistant coating, protecting them from rust, road salt, and harsh weather conditions. Whether your truck spends its time in snow, mud, or dry, dusty terrain, these shocks are made to withstand the elements and keep performing for years to come. Better yet, installation is straightforward, with a direct bolt-on design that uses factory mounting points. There’s no need for custom fabrication or complicated modifications—just remove the old shocks and replace them with the Bilstein 5100s. Since they’re compatible with stock springs and mounts, this kit is an easy way to improve handling and ride quality without overhauling your entire suspension.
