Important notes before you order
- Requires frame bracket modification
- Factory 17-18" 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.
- If equipped with a mono-leaf rear spring please use part #UBT4064.
- 2.7L Turbo models must use Diesel kit for proper skid plate fitment due to clearance issue with Intercooler pipe
TRU specialist notes
From the Trucks R Us fitment and install team, beyond the manufacturer's information.
- Plan for a professional wheel alignment after installing any lift or leveling kit.
- Going to bigger tires as well? Speedometer recalibration may be needed, and some tire and wheel combinations need trimming. Check the recommended wheels and tires, or ask us before you order.

Overview
Up the ante of your Chevy Trail Boss and GMC AT4 1500 truck with a 4-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 NX2 Nitro or premium FOX 2.0 Performance Series shocks.
FOX Performance Elite
FOX 2.5 Performance Elite shocks offer next level performance for on-road comfort and off-road comfort capability. Tuned and ready to install right out of the box, these bolt-on 2.5-inch diameter shocks are built for abuse and packed with race-proven technology. They include a remote reservoir for additional fluid capacity to keep your shocks running cool so you can push the limits in the rough terrain. The DSC adjuster adds remarkable versatility and precise tuning with a simple twist of either two adjuster knobs, offering 10 separate low-speed and 12 high-speed compression levels, with a black anodized aluminum reservoir to increase cooling efficiency.
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
BDS maximizes ground clearance with their heavy duty 1/4-inch thick laser cut perfect fit crossmembers. Paired with a front skid plate system that bolts together to create a rigid subframe while adding extra protection.
