Product Details

BDS steps up the performance and capability of the Chevy Silverado and GMC Sierra 1500 trucks with 4-inch suspension lift kit. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 33" tires

This kit takes advantage of BDS's tried and true high-clearance design for improved ground clearance, strength, and offroad protection while correcting suspension and steering geometry for great on-road handling characteristics. Up front, the kit utilizes top mounted strut spacers, high-arched 1/4-inch thick steel crossmembers along with a multipiece differential relocation brackets and heavy duty skid plates built for offroad protection. Steering geometry is corrected at the new taller ride height with CNC-machined ductile iron steering knuckles and replacement tie rod ends allowing for ESC system compatibility. These combined with the provided sway bar drops, bump stop extensions, brake line brackets, CV spacers, supplied hardware and more provide a comprehensive front suspension lift ready for whatever you throw at it.

In the rear BDS offers a heavy duty lift block to lift and level that stance. The lift block installs in place of the stock block and retains ride quality and load capacity. Also for the rear are new u-bolts, brake line brackets and precision tuned NX2 Nitro or premium FOX 2.0 Performance Series shocks.
