BDS 4.50-Inch Suspension Lift Kit with Rear Lift Blocks and NX2 Nitro Shocks (11-19 Sierra 3500 HD w/ Factory Overload Springs)

Balanced 4.50-Inch Lift with Restored Geometry. This BDS 4.50-Inch Suspension Lift Kit with Rear Lift Blocks and NX2 Nitro Shocks uses coil-spacer technology up front and four-inch blocks in the rear to raise the vehicle evenly, maintaining factory suspension angles for predictable handling. The NX2 Nitro shocks deploy a dual-valve design to control rebound and compression at each wheel, delivering confident steering response and axle articulation whether you’re loaded for work or navigating off-road terrain.

Durable Components for Heavy-Load Performance. Designed for models with factory overload springs, the kit includes reinforced lift blocks and U-bolts to support extra payloads without sagging. Extended brake lines preserve full wheel travel, and a drop pitman arm corrects steering geometry post-lift. All parts feature corrosion-resistant coatings for years of dependable service under demanding conditions.

Installation. This product bolts to factory suspension mounts with the supplied brackets, blocks, shocks, and hardware—no frame drilling required
