BDS Suspension 4.5 Inch Lift Kit Chevy Silverado or GMC Sierra 2500HD/3500HD 2011-2019

Improve the stance, performance, and capability of your 2011-2019 Chevy Silverado and GMC Sierra 2500 HD 4WD with a BDS 4.5-inch lift kit. For maximum ground clearance, BDS designed a No Torsion Bar Drop System where the torsion bars are mounted directly to the top of the lower a-arm eliminating the need to drop the torsion bar cross-member.

This kit includes everything necessary to set your truck up right with clearance for up to 35 inch 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 torsion bar relocation brackets, 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 links, bump stop extensions, stainless steel brake lines, CV spacers, supplied hardware and more provide a comprehensive front suspension lift ready for whatever you throw at it.

In the rear BDS offers replacement lift blocks 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 is a u-bolt flip kit for max clearance 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.

Rear Lift Option 3 Inch Block Without Overload

Determine if your truck was manufactured with or without top-mounted overload springs on the rear leaf springs.
