Product Details
The Bilstein B8 shocks are built for a 2011-2026 Chevrolet Silverado 2500 HD (GMT900/K2XX/T1XX) that has been lifted or leveled, valved for the taller ride height rather than fighting it.
This is a direct-fit part. It mounts in the original locations with the original hardware, so nothing needs modifying, and it carries Bilstein's limited lifetime warranty.
Features
- 46mm monotube design ensures consistent, fade-free performance in all conditions
- Self-adjusting deflective disc valving reacts immediately to surface changes enabling maximum vehicle control
- Remote reservoir increases shock oil capacity for greater heat dissipation
