Product Details
Lifting or leveling a 1999-2018 GMC Sierra 1500 (GMT800/GMT900/K2XX) changes what the dampers have to do. The Bilstein B8 shocks are built for that taller stance and stay composed on rough ground.
Bilstein has built suspension in Germany since 1954, and supplies the same engineering to manufacturers as original equipment. The build quality is the reason these outlast what they replace, and they are covered by a 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
