BDS 4 Inch Lift Kit | Chevy Silverado 1500 ZR2 & GMC Sierra 1500 AT4X (2022-2026) | 3.0 Duramax Diesel

Overview

This 4-inch suspension lift kit from BDS Suspension is designed for the Chevy Silverado 1500 ZR2 and GMC Sierra 1500 AT4X equipped with the 3.0L Duramax diesel engine. The kit improves stance, performance, and capability while providing clearance for up to 35–37-inch tires. It leverages BDS's high-clearance design for enhanced ground clearance, strength, and off-road protection, while 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, a multi-piece differential relocation bracket, and heavy-duty skid plates. CNC-machined ductile iron steering knuckles and replacement tie rod ends correct steering geometry while maintaining ESC system compatibility. Sway bar drops, bump stop extensions, and brake line brackets are also included. In the rear, a heavy-duty lift block installs in place of the stock block to lift and level the stance while retaining ride quality and load capacity. New U-bolts and shock relocation brackets ensure the factory Multimatic shock system operates without error.
