  • $3,787.79

Take your late model Chevy Trail Boss or GMC AT4 to the next level with one of the BDS 2.5" high clearance coilover systems.
These kits net 2.5" lift on a Trail Boss/AT4, however final ride height is similar to a GM1500 with 4" of lift 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 available with optional DSC (dual speed compression) adjustment technology built in to allow 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. Adjustments can be made by simply twisting the knobs located on the end of the reservoir. To go along with the coilovers are 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 2.5" 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.

No Fine Print Warranty
BDS stands behind its products and that’s evident by their No Fine Print Warranty. This no-BS warranty protects the original purchaser against breakage, bending, sagging, or any other usage failure. This “no fine print” lifetime replacement warranty extends to cover all BDS hard parts as well as bushings. Exclusions would be product finish and wearable items such as shock/stabilizer cylinders, tie rod ends and ball joints that would fall under the separate Limited Lifetime Warranty policy. Beginning February 1, 2020 all new kit purchases include the No Fine Print Warranty on bushings.

Limited Lifetime Warranty (for wearable items)
Wearable items include shock/steering stabilizer cylinders, ball joints and tie rod ends. BDS Suspension Co. warrants to the original retail purchaser that its these wearable parts are free from defects in material and workmanship for so long as they own the vehicle. Excluded from this warranty are the finish of the product. Defects in material and workmanship do not include such things as dented cylinders or bent rods caused by obvious side impact, rust or corrosion. A shock absorber is a wear item and over time will experience diminished damping resistance due to normal component wear. This is not a defect in material or workmanship and is therefore not warrantable.
