Take your Chevy Trail Boss and GMC AT4 1500 truck to the next level with 4-inch suspension lift kit by BDS. 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.

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 NX2 Nitro or premium FOX 2.0 Performance Series shocks.

HD Upper Control Arms (UCAs)

Built for strength performance and increased travel these upper control arms are ready to bolt-in with most leveled/lifted trucks. 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.

High Clearance Crossmembers

  • Factory 17" and 18" wheels cannot be reinstalled due to tie rod end interference stock 20" wheels can be reinstalled.
  • 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.
  • 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.
