Important Notes
*IMPORTANT*: GM is producing several knuckle/control arm configurations in 2014-2017 models trucks. Cast Steel control arm equipped models will require the "Cast Steel Control Arm" kit. Stamped Steel and Aluminum control arm equipped models will require the "Aluminum Control Arm" kit. Be sure to verify which factory control arms your truck has before ordering by referecing our help images when customizing your kit.
- Strut compressor required
- Requires frame bracket modification
- Requires differential modification to clear electric power steering
- Vehicles came from the factory with several knuckle/control arm configurations requiring specific kit selections. Be sure to reference the important notes and images above to determine the correct control arm selection for your application.
- Factory 17" and 18" wheels cannot be reinstalled due to tie rod end interference
- All wheel drive models require drive line modification.
Features & Benefits
- High clearance crossmember design maximizes ground clearance
- Robust steering knuckles maintain ESC system compliance
- HD skid plate system improved offroad protection

- Factory Protection Plus drivetrain warranty included
The BDS 4-inch lift kit is an amazing upgrade for your 2014-2018 Chevy Silverado and GMC Sierra 1500 that will leave others in envy. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 33" 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 full length replacement strut shocks, 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. 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 both replacement lift block and full Glide-Ride leaf spring options 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 FOX 2.0 Performance Series shocks.
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.
Heavy Duty Steering Knuckles
BDS corrects steering geometry at the new taller ride height using a pair of high-strength, CNC machined ductile cast iron steering knuckle design to work with factory tie rod ends to maintain steering angles for proper function and ESC compatibility.
