Description

Up the ante of your Chevy Trail Boss and GMC AT4 1500 truck with a 2.5-inch suspension lift kit featuring FOX Performance Elite coil-over shocks. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 35" tires. These kits feature proprietary FOX 2.5 coil-over shocks designed specifically to bolt-on performance for increase travel and the ability to soak up the roughest terrain along with smooth on-road comfort.

This kit takes advantage of BDS's tried and true high-clearance design for improved ground clearance, strength, and offroad protection while correcting suspension and steering geometry for great on-road handling characteristics. Up front, the kit utilizes top mounted strut spacers, upper control arms, high-arched 1/4-inch thick steel crossmembers along with a multipiece differential relocation brackets and heavy duty skid plates built for offroad protection.

Steering geometry is corrected at the new taller ride height with CNC-machined ductile iron steering knuckles and replacement tie rod ends allowing for ESC system compatibility. These combined with the provided sway bar drops, bump stop extensions, brake line brackets, CV spacers, supplied hardware and more provide a comprehensive front suspension lift ready for whatever you throw at it. In the rear BDS offers a heavy duty lift block to lift and level that stance. The lift block installs in place of the stock block and retains ride quality and load capacity. Also for the rear are new u-bolts, brake line brackets and precision tuned premium FOX 2.0 Performance Series shocks.

They use 1.5" OD x .120-wall tubular construction with an indexed ball joint cup to correct the ball joint positioning allowing additional down travel and camber adjustment. At the frame mounting ends are durometer-specific rubber bushings for maintenance-free operation while at the other end a quality greaseable ball joints for smooth, quiet operation and superior durability. Arms are finished in a durable black powder coat with a billet aluminum dust cap ready for installation right out of the box.
