These FOX coilover systems are designed to build on the stout factory front suspension design on the Chevy/GMC 1500 trucks and take performance to the next level while leveling out the stance.
More that just a "leveling kit", at the heart of this system is a pair of specially tuned FOX 2.0 Performance Series IFP coilovers. These non-reservoir coilovers are preset for the correct lift height right out of the box and use a threaded body to allow preload adjustment. 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 all preloaded with coil springs ready for easy installation.
Also supplied for the front are a pair of performance upper control arms (UCAs) designed for improved strength and suspension travel. Built from thick wall 1.5" 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 to result in a level stance in no change in tow/load capacity. A pair of FOX 2.0 performance series IFP shocks are supplied to match the front performance.

When its time to step your game up these FOX coilover systems are ready to do battle. More that just a "leveling kit", this system steps up to specially tuned FOX 2.5 Factory Race Series coilovers featuring DSC (dual speed compression) adjustment.
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 remove reservoirs with mounting brackets. The DSC 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.

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.

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.
Improve the look and capability of your 2019-2022 Trail Boss or AT4 truck with these new 1.5" coilover lift systems from BDS Suspension.
*Trimming may be required*
If you're looking to optimize performance and capability this 2.5" coilover system is for you. While these kits net 2.5" of lift on a Trail Boss/AT4, ride height is similar to a 4" lift on a standard GM1500 truck. Building on the tried-and-true BDS high clearance design these kits maintain on-road handling and performance while upping the ante with FOX 2.5 factory race series remote reservoir coilovers for truly next level performance on any terrain. These coilovers are available in standard or DSC (dual speed compression) adjustable versions and pair with a set of FOX 2.0 IFP performance series rear shocks. Additionally high strength 1/4" steel crossmembers, precision machined ductile iron steering knuckles, heavy duty tie rod ends, multipoint differential drop brackets, front and differential skid plates, performance series upper control arms, sway bar relocation, rear block kit and brake line relocation brackets come together to form a quality systems designed to enhance your late model GM truck with clearance for up to 35" tires.

These 4" lift kits come complete with everything you need to properly lift your Trail Boss/AT4 and allow clearance for 35-37" tires. The goal with these kits is to build off the factory steering and suspension geometry to offer the optimized strength, safety, and performance you've come to expect from BDS Suspension. While these kits net 4" of lift on a Trail Boss/AT4, ride height is similar to a 6" lift on a standard GM1500 truck. Parts list includes high strength 1/4" steel crossmembers, precision machined ductile iron steering knuckles, heavy duty tie rod ends, multipoint differential drop brackets, front and differential skid plates, performance series upper control arms, top mounted strut spacers, sway bar relocation, brake line relocation, rear block kit and your choice of gas shocks. Kits allow compatibility with more tire/wheel options than other lift kits on the market. These systems are not only built for daily driving, but will handle most any offroad excursion you want to tackle and provide extra ground clearance and heavy duty skid plates. Take your GM truck to the next level with BDS.

Shotpeening increases tensile strength and reduces fatigue while lessening the material thickness required. The thinner material allows for increased wheel travel and provides a softer ride.
Bolt-style leaf alignment clamps prevent leaves from fanning out and allow the leaves to twist and flex, yielding higher articulation.
Each spring is preset using hydraulic stress to reduce fatigue in the steel and prevent sagging.
Some applications include leaf springs with steel encased rubber bushings. Other applications include blue urethane bushings.
Anti-friction pads are placed between the leaves to reduce friction within the spring and noise from metal-to-metal contact.
Tapered and roll-pointed leaves add flexibility and provides an even deflection rate. Tapering allows a smoother transition between leaves as compression takes place, resulting in a softer ride with increased wheel travel.
Springs are either cold wound with chrome silicon 9254 or hot wound with 5160 to guarantee long life.
BDS coil springs are designed to withstand full coil bind. In other words, you can smash our coils to totally flat and they will return to their original height.
A polyester based powder coat is applied to ensure flexibility and durability.
Each spring is preset with a hydraulic stress to reduce fatigue in the steel and prevent sagging.
Shotpeening increases tensile strength and allows for maximum wheel travel without sacrificing the life of the spring.
