Description
Ultimate Lift with Premium Damping. This BDS kit elevates your Sierra 3500 HD by 6.5 inches using adjustable FOX 2.5 Performance Elite coil-overs up front and FOX 2.0 monotube shocks in the rear. The remote-reservoir design ensures consistent damping during extended, aggressive off-road use.
Rear Support and Stability. Heavy-duty steel lift blocks maintain proper rear spring geometry and add load-bearing capacity without the complexity of overload springs. The integrated U-bolts and brackets ensure a secure, noise-free installation.
Installation. This product installs by replacing factory struts with coil-over assemblies, installing rear lift blocks under the springs, and bolting in FOX shocks using the supplied hardware—no cutting or welding is required, though professional alignment is recommended.
Application. This BDS 6.50-Inch Suspension Lift Kit with Rear Lift Blocks, FOX 2.5 Performance Elite Coil-Overs and FOX 2.0 Performance Shocks fits 2020–2026 Sierra 3500 HD SRW models powered by the 6.6 L Duramax and without factory overload springs.
