Upgrade the performance, stance, and off-road capability of your 2025–2026 Chevy Trail Boss or GMC AT4 1500 Diesel 4WD with the BDS 2.5 Inch Lift Kit featuring FOX 2.5 Performance Elite Coilover Shocks. Designed specifically for factory lifted Trail Boss and AT4 trucks, this suspension system improves ride quality, suspension travel, and durability while allowing clearance for larger tires.
The system features FOX 2.5 Performance Elite coilover shocks with remote reservoirs and Dual Speed Compression (DSC) adjusters, delivering exceptional damping performance and precise adjustability for both on-road comfort and aggressive off-road driving. The larger shock body increases oil capacity to improve heat dissipation and maintain consistent performance under demanding conditions.
To maintain proper suspension geometry and strength, the kit includes heavy-duty tubular upper control arms constructed from 1.5-inch OD steel tubing with indexed ball joint cups. These arms improve camber alignment and allow additional suspension travel on lifted applications while maintaining smooth and quiet operation using durable rubber bushings and premium greaseable ball joints.
The front suspension system also incorporates high-clearance laser-cut crossmembers, differential relocation brackets, and heavy-duty skid plates to improve ground clearance while protecting key drivetrain components. CNC-machined ductile iron steering knuckles and replacement tie rod ends help maintain proper steering geometry and compatibility with the vehicle’s ESC system.
In the rear, the system uses a heavy-duty lift block and extended U-bolts to properly level the vehicle while maintaining factory load capacity. Rear suspension performance is handled by FOX Performance Series shocks, delivering improved ride control and damping performance across a wide range of terrain.
With clearance for up to 35-inch tires, this BDS suspension system delivers an aggressive stance and improved capability while maintaining the durability and reliability expected from BDS Suspension.
