BDS 4 Inch Lift Kit | Chevy Silverado & GMC Sierra 1500 4WD Diesel (2019-2024) | FOX 2.0 Rear & Front

Configured with FOX 2.0 Performance Series shocks at both the rear and front. FOX 2.0 shocks feature a 2-inch impact extruded and CNC machined 6061-T6 clear anodized aluminum one-piece body, a 5/8-inch hard chrome plated heat-treated alloy steel shaft, race-developed high-flow piston design, application-specific valving, and an internal IFP mono-tube reservoir design for maximized performance and rust resistance.

Overview

BDS Suspension's 4-inch suspension lift kit is designed to improve the stance, performance, and capability of the 2019–2024 Chevy Silverado and GMC Sierra 1500 4WD Diesel trucks. This comprehensive kit provides clearance for up to 33-inch tires and includes all necessary components for a complete front and rear suspension lift. The kit takes advantage of BDS's high-clearance design for improved ground clearance, strength, and off-road protection while correcting suspension and steering geometry for proper on-road handling.

Up front, the kit utilizes top-mounted strut spacers, high-arched 1/4-inch thick steel crossmembers, multi-piece differential relocation brackets, and heavy-duty skid plates. Steering geometry is corrected at the new ride height with CNC-machined ductile iron steering knuckles and replacement tie rod ends, maintaining ESC system compatibility. Sway bar drops, bump stop extensions, brake line brackets, CV spacers, and all required hardware are also included. In the rear, a heavy-duty lift block replaces the stock block to lift and level the stance while retaining ride quality and load capacity, along with new U-bolts, brake line brackets, and rear shocks.

Important Notes

• Requires frame bracket modification.
• Factory 17-inch and 18-inch wheels cannot be reinstalled due to tie rod end interference; stock 20-inch wheels can be reinstalled.
• 17-inch wheels with 4.5-inch backspacing should be test fit prior to mounting the tire to ensure proper clearance to the steering knuckle and tie rod.
• All aftermarket wheels should be test fit prior to mounting the tire to ensure proper clearance to the brake caliper. Some wheel profiles will not clear the brake caliper. These can be test fitted before the vehicle is lifted in a stock condition.
• 2.7L models must use the Diesel kit for proper skid plate fitment.
• If equipped with a mono-leaf rear spring, please use part #UBT4064.
• Will not fit models equipped with ARC.
