Product Details

Lifting or leveling a 2011-2026 GMC Sierra 3500 HD (GMT900/K2XX/T1XX) changes what the dampers have to do. The Bilstein B8 shocks are built for that taller stance and stay composed on rough ground.

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
