Product Details

Lifting or leveling a 2007-2026 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.

The monotube design is what sets Bilstein apart. A single high-pressure gas chamber keeps the oil from aerating, so the damping stays consistent on a rough road instead of fading as the unit heats up.

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
