Important notes before you order

Factory 17", 18" and 20" wheels cannot be reinstalled. See instructions for detailed wheel/tire fitment notes.
Minor metal trimming may be required with 35x12.50R20 on 20x9 w/5-5.5" BS
Requires minor welding Coilovers are preset for DIESEL engine models. The use of the coilovers on GAS engine models is not recommended due to providing too much lift. Available preload adjustment is typically not enough to achieve desired ride height.
Dually Models will require aftermarket 20" wheels with a max tire size of 285/60/20.

TRU specialist notes

From the Trucks R Us fitment and install team, beyond the manufacturer's information.

Plan for a professional wheel alignment after installing any lift or leveling kit.
Going to bigger tires as well? Speedometer recalibration may be needed, and some tire and wheel combinations need trimming. Check the recommended wheels and tires, or ask us before you order.

Overview

Designed to improve stance, performance, and capability, the FOX 2.5 Performance Elite Coilover kit includes everything necessary to set your 2011-2019 Chevy Silverado/GMC Sierra 2500/3500 HD truck up right with clearance for up to 35" tires. These kits feature proprietary FOX 2.5 Performance Elite coilover shocks, designed for bolt-on performance, increased travel, and the ability to soak up the roughest terrain, while maintaining smooth on-road performance.

In addition to replacing the factory torsion bars, the upper and lower control arms are upgraded to improve strength and travel, and to accommodate the new coilovers. The new upper control arms are fabricated from large 1.5" OD x .120-wall tubing, fully TIG welded for the highest quality, strength, and durability. To complement the uppers, the new lower control arms are built from high-strength steel, fully boxed and internally gusseted.

This kit adheres to BDS's engineering standards to improve ground clearance, strength, and off-road protection while correcting suspension and steering geometry for outstanding on-road handling. Up front, the kit utilizes FOX 2.5 coilover shocks, heavy-duty tubular upper control arms, fully boxed and gusseted lower control arms, and multipiece differential relocation brackets to maintain correct CV angles. These, combined with the provided sway bar links, supplied hardware, and more, provide a comprehensive front suspension lift ready for whatever you throw at it.

In the rear, BDS offers replacement lift blocks to lift and level that stance. The lift block installs in place of the stock block and retains ride quality and load capacity. Also for the rear is a U-bolt flip kit for max clearance and precision-tuned FOX 2.0 Performance Series or Performance Elite Series 2.5” shocks for ultimate off-road performance.

FOX 2.5 Performance Elite Coilovers

FOX Performance Elite 2.5 coilovers deliver next-level performance and on-road and off-road comfort. Tuned and ready to install right out of the box, these bolt-on 2.5-inch diameter coilovers are built for abuse and packed with race-proven technology. They include a remote reservoir for additional fluid capacity, helping keep your shocks running cool so you can push the limits in rough terrain.

DSC Adjustment

FOX Performance Elite 2.5 coilovers come standard with DSC (dual-speed compression) adjustment to tune high-speed and low-speed compression damping, providing on-road control and making it easy to dial in more aggressive damping off-road. Tuning is a simple twist of the two clearly defined knobs with immediate feedback to dial it in for any terrain

HD Control Arms

Built for strength, performance, and increased travel, these control arms are ready to bolt in. The upper arms use 1.5" OD x .120-wall tubular construction with an indexed ball joint cup to correct the ball joint positioning, allowing additional down travel and camber adjustment. The new lower control arms are built from high-strength steel, fully boxed with internally gusseted. At the frame mounting ends, durometer-specific rubber bushings provide maintenance-free operation, while at the other end, quality greaseable ball joints offer smooth, quiet operation and superior durability. Arms are finished in a durable black powder coat with a billet aluminum dust cap ready for installation right out of the box.
