4.5-inch Lift Kit with NX2 Nitro Shocks

The BDS Suspension 4.5-inch lift kit provides a comprehensive upgrade for your 2014-2018 Chevy Silverado and GMC Sierra 1500 4WD, enhancing both aesthetics and off-road capability. The kit boasts a high-clearance design with 1/4-inch thick steel crossmembers and heavy-duty skid plates to maximize ground clearance and offer robust underbody protection. Up front, CNC-machined ductile iron steering knuckles correct suspension and steering geometry for improved on-road handling and maintain Electronic Stability Control (ESC) system compliance. Multipoint differential relocation brackets ensure proper axle placement and optimize CV angles. For the rear lift, BDS offers two options: a 3-inch block kit, which replaces the stock block to net 2 inches of lift and level the vehicle while maintaining factory load capacity and pinion angles, or a full set of Glide-Ride leaf springs that eliminate the need for a block, reduce axle wrap, and provide a stable feel. Both rear options are complemented by precision-tuned NX2 Nitro or FOX 2.0 Performance Series shocks, tailored to the specific lift height and vehicle application. The FOX 2.0 shocks feature a 2-inch impact-extruded aluminum body, IFP monotube design, and a massive 5/8-inch hard chrome-plated shaft, while the NX2 Nitro shocks utilize a nitrogen-charged twin-tube design with 10-stage velocity-sensitive valving. A critical fitment note for 2014-2018 GM trucks is the variation in factory control arm types. Models equipped with Cast Steel control arms require a specific kit, while those with Aluminum or Stamped Steel control arms need a different configuration. It is essential to verify your truck's factory control arm type before ordering by referencing the provided images. This kit is designed to accommodate up to 33-inch tires, with recommended wheel and tire combinations specified for 17, 18, and 20-inch wheels. Trimming may be necessary depending on the chosen wheel and tire setup.
