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

These 4" lift kits come complete with everything you need to properly lift your Trail Boss/AT4 and allow clearance for 35-37" tires. The goal with these kits is to build off the factory steering and suspension geometry to offer the optimized strength, safety, and performance you've come to expect from BDS Suspension. 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. Parts list includes 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, top mounted strut spacers, sway bar relocation, brake line relocation, rear block kit and your choice of gas shocks. Kits allow compatibility with more tire/wheel options than other lift kits on the market. These systems are not only built for daily driving, but will handle most any offroad excursion you want to tackle and provide extra ground clearance and heavy duty skid plates. Take your GM truck to the next level with BDS. As with all BDS lift kits, these new 4" lift kits are backed by Factory Protection Plus for piece of mind wherever your adventures may take you. Factory Protection Plus includes BDS's exclusive No Fine Print Warranty, FMVSS No.126 ESC System compatibility and a 5-year, 100,000-mile drivetrain warranty.
