BDS 4" Coilover Lift Kit | Diesel | 2019-2023 Chevy / GMC 1/2 Ton Truck 4WD Trail Boss or GMC AT4

4" High Clearance Coilover Systems for Chevy Trail Boss or GMC AT4.

If you're looking to optimize performance and capability this 4" coilover system is for you. While these kits net 4" of lift on a Trail Boss/AT4, ride height is similar to a 6" lift on a standard GM1500 truck. Building on the tried-and-true BDS high clearance design these kits maintain on-road handling and performance while upping the ante with FOX 2.5 factory race series remote reservoir coilovers for truly next level performance on any terrain. These coilovers are available in standard or DSC (dual speed compression) adjustable versions and pair with a set of FOX 2.0 IFP performance series rear shocks. Additionally high strength 1/4" steel crossmembers, precision machined ductile iron steering knuckles, heavy duty tie rod ends, multipoint differential drop brackets, front and differential skid plates, performance series upper control arms, sway bar relocation, rear block kit and brake line relocation brackets come together to form a quality systems designed to enhance your late model GM truck with clearance for 35- 37" tires.

Important Kit Notes

• 1. Does NOT fit Diesel Models
• 2. Requires frame bracket modification
• 3. Will not fit models with Adaptive Ride Control (ARC)
• 4. Factory 17-18" wheels cannot be reinstalled due to tie rod end interference, stock 20" wheels can be reinstalled
• 5. 17" wheels with 4.5" backspacing should be test fit prior to mounting the tire to ensure proper clearance to the steering knuckle / tie rod
• 6. 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
• 7. Actual ride height on coilover kits is closer to 4.5" of lift on Trail Boss/AT4
