BDS Suspension BDS1854H Suspension Lift Kit

Give your Chevy Silverado High Country and GMC Denali 1500 trucks a new look by installing a 4-inch suspension lift kit by BDS Suspension. Works with trucks equipped with Adaptive Ride Control only. Designed to improve stance, performance, and capability, 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 top mounted strut spacers, 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 and replacement tie rod ends allowing for ESC system compatibility.

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 a heavy duty lift block 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 and shock relocation brackets to retain the ARC system without error.

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 replacement tie rod ends to maintain steering angles for proper function and ESC compatibility.
