This configuration pairs the FOX 2.5 Performance Elite front coil-overs with FOX 2.5 Performance Elite rear shocks. The rear shocks share the same 2.5-inch impact extruded aluminum body, massive 7/8-inch hard chrome plated alloy steel shaft, external reservoir design, and DSC Dual Speed Compression Adjuster as the front units, delivering consistent front-to-rear performance tuning and full serviceability.
Overview
The BDS 6-inch lift kit for the 2019–2026 Chevy Silverado and GMC Sierra 1500 4WD (Diesel) is engineered to improve stance, performance, and off-road capability while providing clearance for up to 35-inch tires. The kit centers on FOX 2.5 Performance Elite coil-over shocks up front, designed specifically as bolt-on units for increased travel and improved terrain absorption without sacrificing on-road comfort. A high-clearance crossmember design, CNC-machined ductile iron steering knuckles, and a comprehensive hardware package address suspension and steering geometry at the new ride height. In the rear, a heavy-duty lift block replaces the factory block to lift and level the stance while retaining ride quality and load capacity, complemented by new U-bolts and brake line brackets.

Important Notes
- Requires frame bracket modification.
- Factory 17–18-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 stock condition.
- Actual ride height on coil-over kits is closer to 6.5 inches of lift.
- If equipped with a mono-leaf rear spring, please use part #UBT4064.
- 2.7L Turbo models should use the Diesel kit for proper skid plate fitment.
- Will not fit models equipped with ARC.
