Coldwater, MI: BDS Suspension adds new options for the 4" and 6"  high clearance systems for the 2019-2020 Chevy/GMC 1500 trucks. These new coilover systems join the current lineup offering improved performance and capability. 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 systems join the exising 6” lift options as an intermediary between the standard (strut spacer) kits and full blown FOX 2.5 R/R coilover systems by utilizing FOX 2.0 performance series IFP (non-reservoir) coilovers and 2.0 PS IFP rear shocks. These new suspension systems utilize the tried and true high-clearance IFS design that has made BDS the preferred suspension lift for late model GMs updated to correct suspension, steering and driveline geometry for improved on road comfort and off-road performance and combine with FOX 2.0 coilovers and shocks for improved performance. As with all BDS suspension systems these new 6” coilover systems options are backed by Factory Protection Plus offering you peace of mind for your adventure. This includes a BDS No Fine Print Warranty, FMVSS No.126 compliance testing and a 5year-100,000mile drivetrain warranty. Build your Chevy/GMC up right with BDS Suspension.

At the heart of these new systems are a pair of precision tuned FOX 2.0 performance series (non-reservoir) coilover struts designed for use with the factory coil spring and top plate. These non-reservoir FOX coilovers offer improved on-road and off-road performance and allow easy setup with 2 snap ring grooves for either 4" or 6" of lift. They are a direct bolt-in replacement for the factory strut assemblies and improve damper performance featuring a 2.0" extruded and machined 6061 T6 aluminum body for better heat dispersion, along with an internal floating piston (IFP) to eliminate oil aeration, FOX’s proprietary internals, 5/8" hard chrome plated heat treated alloy shaft. 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 these lift systems, the factory block is replaced with either a 3" or 5" lift block and longer u-bolts to lift and level the stance depending on front lift height. 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 either of these new 4" and 6" coilover systems from BDS Suspension.
