 The BDS 6-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 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 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.
