These 1.5" DSC Coilover Systems are designed to build on the stout factory front suspension design on Chevy Silverado 1500 Trail Boss and GMC Sierra 1500 AT4 trucks and take performance to the next level.

Based on the 3.5" kits for the standard GM trucks and will net 1.5" over the factory taller ride height of the Trail Boss/AT4. At the heart of these 1.5" systems are a pair of specially tuned FOX 2.5 factory race series DSC coilovers. These coilovers are backed by FOX's racing pedigree, 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 remote reservoirs with mounting brackets. The DSC (dual speed compression) reservoir allows for easy tool-free adjustment of high-speed and low-speed compression adjustment settings to further dial in the damping to the terrain and ride preferences. Also supplied for the front end are a pair of performance upper control arms (UCAs) designed for improved strength and suspension travel. Built from thick wall 1.5" DOM tubing, these UCAs utilize an indexed ball joint cup to reposition the upper ball joints and allowing more droop travel. These arms come fully assembled right out of the box with high quality greaseable ball joints and rubber bushings for long life, quiet operation and superior corrosion resistance over uniballs and heims.

In the rear of these lift systems the factory leaf springs are retained and 2" lift comes from a replacement set of lift blocks. Also supplied for the rear of these systems are your choice of FOX 2.0 performance series IFP shocks or upgraded FOX 2.5 factory series shocks to match the front performance and adjustability. These kits come finished in a durable black powdercoat finish 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, ESC System compatibility and a 5year-100,000 mile drivetrain warranty to match the dealer. Improve the look and capability of your 2019-2020 Trail Boss or AT4 truck with these new 1.5" coilover lift systems from BDS Suspension.
