GMC Sierra 1500 Front Shock Absorber - Bilstein - B8 5100 Series - `19-`24. A ride-height adjustable monotube front shock designed for 2019–2024 GMC Sierra 1500 models with OE coilover-style front suspension. It lets you level the truck’s front while retaining factory spring rates.
The Bilstein B8 5100 combines a 46mm monotube body with a digressive piston and self-adjusting deflective disc valve to deliver consistent, fade-resistant damping whether you’re towing, hauling, or driving off-road. Multiple snap-ring grooves on the shock body allow adjustable spring-seat positions, offering approximately 0–2.75" of front lift depending on application. This option is a practical alternative to coil spring spacers, preserving handling characteristics, increasing wheel travel, and providing predictable performance across varied conditions.
