- Factory 17-18" wheels cannot be reinstalled due to tie rod end interference, stock 20" wheels can be reinstalled.
- 17" wheels with 4.5" backspacing should be test fit prior to mounting the tire to ensure proper clearance to the steering knuckle / tie rod.
- All aftermarket wheels should be test fit prior to mounting the tire to ensure proper clearance to the brake caliper. Some wheel profiles will not clear the brake caliper. These can be test fitted before the vehicle is lifted in a stock condition.

Coldwater, MI: BDS Suspension raises the bar with new 4" high clearance coilover systems for the 2019-2020 Chevy/GMC 1500 trucks. These new 4" coilover systems and coilover upgrade kits join the current 4" and 6" lineup of BDS suspension options offering next level performance and capability. They can also be installed on the new Trail Boss and AT4 models to net 2.5" of lift. These kits are based around the tried and true high clearance technology that has made BDS the go to for GM suspension lifts, these systems have been designed from the ground up to get the more out of your truck with the most ground clearance on the market. This new 6" lift system is the first of many new BDS options to come available for the new trucks bringing you on road comfort, off-road capability and clearance for 35" tires. While some companies build "kits" to fit larger tires, BDS Suspension prides itself in engineering complete suspension systems designed to take your vehicle's performance to the next level while retaining OE-level functionality. Case in point the (NHTSA) National Highway Traffic Safety Administration's FMVSS No.126 compliance standards requiring any aftermarket modification to not adversely effect the vehicle's electronic stability control (ESC) system performance in the event of an evasive maneuver. These new kits have been independently tested and certified compliant with these standards with up to 35" tires.

At the heart of these new systems are a pair of precision tuned FOX 2.5 factory race series remote reservoir coilovers engineered to outperform on and offroad as they soak up the terrain. These coilovers are preset for the correct lift height right out of the box to provide optimal performance and direct bolt-in replacement for the factory strut assemblies. They feature a smooth bore and honed seamless alloy body, 7/8" hardened steel carbon shaft, Eibach coil springs and black anodized machined 6061-T6 billet aluminum mounts along with remove reservoirs with mounting brackets. The reservoir is avaialble with optional DSC (dual speed compression) adjustment technology built into the remote reservoir. DSC allows for easy adjustment of the vehicle's suspension compression dampening so you can dial in the ideal ride performance to soak up the bumps, both large and small. The DSC has 12 adjustment points for the high speed compression as well as 10 adjustment points for the low speed compression allowing you to make large or small changes to further improve your performance. Adjustments can be made by simply twisting the knobs located on the end of the reservoir. No tools or shop adjustments needed, allowing you to tune the suspension out on the trail. Complimenting the coilovers, BDS utilizes a pair of specially designed 1/4" thick laser cut high clearance crossmembers to maximize clearance and provide a solid mounting point for the OE lower control arms. These paired with the 3-piece heavy duty front skid plate system create a rigid subframe while adding protection for vital steering and driveline components. In place of the factory steering knuckles a pair of specially designed ductile iron replacement steering knuckles are supplied to maintain proper steering geometry for ESC system compatibility. These connect to the factory steering with a pair of heavy duty replacement tie rod ends included in the kit. The front differential is repositioned with BDS's multipoint relocation bracket system tying into the frame and control arm pockets to further secure the front differential to keep CV axle angles at a minimum. A billet aluminum front driveshaft spacer is also supplied along with longer hardware to allow the reinstallation of the factory driveshaft. A pair of BDS-branded sway bar drop brackets used to correct the operating angle of the factory sway bar as well as created a strong brace between the rear crossmember and the frame. Rounding out the front of this kit are new lower control arm cam bolts to allow alignment and a weld-in frame reinforcement plate for extra strength.

In the rear of this 4" lift system, the factory block is replaced with a 3" lift block and longer u-bolts to lift and level the stance. Also included, BDS supplies brake line and ABS line brackets allow the use of factory brake lines. Specially tuned FOX 2.0 IFP performance series gas shocks are supplied to round out the rear of these kits. All kits come finished in a durable textured black powdercoat and sent with all hardware packs to complete the install along with step-by-step installation instructions. All BDS kits include Factory Protection Plus for the ultimate extended warranty to include BDS's No Fine Print Warranty, FMVSS No.126 (ESC System) compliance certification and a 5year-100mile drivetrain warranty to match the dealer. Improve the look and capability of your 2019-2020 Chevy/GMC 1500 truck with this new 4" lift system from BDS Suspension.
