BDS Suspension 2019-2023 Chevy / GMC 1/2 Ton Truck 4WD Trail Boss / AT4 | 2.5" Coilover Lift Kit (DSL)

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

If you're looking to optimize performance and capability this 2.5" coilover system is for you. While these kits net 2.5" of lift on a Trail Boss/AT4, ride height is similar to a 4" 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 up to 35" tires.
