Take your Duramax to the next level with the BDS 4.5-Inch Suspension Lift Kit, engineered to improve stance, capability, and ground clearance without the added height of a larger lift. Designed for 2011-2019 Chevy Silverado and GMC Sierra 2500HD 4WD models, this high-clearance IFS system delivers impressive off-road performance while maintaining excellent on-road handling characteristics.
Built around BDS’s innovative No Torsion Bar Drop design, the system maximizes ground clearance by eliminating the need to lower the torsion bar crossmember. Heavy-duty crossmembers, differential relocation brackets, skid plates, and ductile cast iron steering knuckles work together to maintain proper suspension geometry, steering performance, and CV axle angles.
The kit includes everything needed for a complete installation, including stainless steel brake lines, sway bar links, differential skid plates, rear lift blocks, and premium BDS shocks. With clearance for up to 35-inch tires, this suspension system provides the perfect balance of aggressive styling, functionality, and durability.
