Improve the appearance and performance of your Chevy Silverado ZR2 and GMC AT4X 1500 trucks with a 4-inch suspension lift kit from BDS Suspension. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your vehicle up right with clearance for up to 35-37" tires.

This kit leverages BDS's proven high-clearance design for enhanced ground clearance, strength, and off-road protection, while also correcting suspension and steering geometry for superior on-road handling. Up front, the kit utilizes top-mounted strut spacers, high-arched 1/4-inch-thick steel crossmembers, along with a multi-piece differential relocation bracket and heavy-duty skid plates built for off-road protection. Steering geometry is corrected with CNC-machined ductile iron steering knuckles and replacement tie rod ends, ensuring compatibility with the ESC system.

These, combined with the provided sway bar drops, bump stop extensions, brake line brackets, 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, retaining ride quality and load capacity. Additionally, for the rear, new U-bolts and shock relocation brackets are installed to ensure the Multimatic shock system operates without error.

Note: This kit works with trucks equipped with Multimatic shocks only.

High Clearance Crossmembers

BDS maximizes ground clearance with their heavy-duty, 1/4-inch-thick, laser-cut, perfect-fit crossmembers. Paired with a front skid plate system that bolts together to create a rigid subframe while adding extra protection.

Heavy Duty Steering Knuckles

BDS corrects steering geometry using a pair of high-strength, CNC-machined ductile cast iron steering knuckle designs that work with replacement tie rod ends, thereby maintaining proper steering angles for optimal function and ESC compatibility.
