Product Details
The Bilstein B8 shocks are built for a 2011-2026 GMC Sierra 3500 HD (GMT900/K2XX/T1XX) that has been lifted or leveled, valved for the taller ride height rather than fighting it.
Inside is Bilstein's monotube design, with the gas and oil separated by a floating piston. That keeps damping consistent when the road turns rough and the unit gets hot, where a lesser damper would go soft.
Features
- 46mm monotube design ensures consistent, fade-free performance in all conditions
- Patented digressive valving instantly reacts to changing surface conditions
- Vehicle specific tuning
