2011-2019 Duramax 2.5" Coilover Conversion Lift Kit (BDS723FDSC)

When you want the best in performance and capability, go with FOX. These race-proven FOX 2.5 factory series remote reservoir coilovers up the ante allowing for next-level damper capability and control all neatly packaged. Designed for bolt-on installation, the engineers at BDS and FOX teamed up to offer this race-winning technology into a bolt-on, pre-tuned Coilover designed to perform and provide correct ride height right out of the box. From valving to spring rate, preload, and hose length; designed to take all the guesswork out of setting your vehicle up and are designed to be used with BDS lift systems. These coilovers use a large 2.5" body, 3" coil springs, 7/8" hardened carbon steel shaft, high flow piston, JM92 advanced racing shock oil, CNC machined 6061 T6 ends, and external remote reservoir to improve damper capability across any terrain. 

This system is available for models equipped from the factory with or without rear top mounted overload springs. Be sure to select the correct option for your model, or choose "No Rear Box Kit" to order this system without rear blocks/ u-bolts.

This new skid plate kit was developed as an OE upgrade to work with our 2-3 inch Coil-over Conversion System for the 2011-18 Chevy 2500HD. The kit includes a replacement skid plate and a front splash guard. These are made from 10ga steel and are much stronger than the factory components. The plates bolt to the factory skid locations with the factory hardware making installation a breeze. The front splash guard includes a stainless steel BDS nameplate. Dimple die holes in the bottom skid add rigidity.

BDS RECOIL traction bars are built to the highest standards for the ultimate performance on and off-road. The bars are fabricated from 2" OD x 3/16" wall steel tubing with a threaded bung welded in toward the axle and a CNC machined end at the frame. The axle mount uses the tried and true BDS large forged flex end and jam nut to take whatever abuse you throw at it. BDS forged flex ends use a forged housing with a large 1-1/4" -12 threaded shank, single-sided snap ring, and 1-piece flex ball for up to 15-degrees of misalignment in either direction. At the frame end, the bar uses a durometer-specific polyurethane bushing installed that free floats in the traction bar utilizing dual-stage internal compression springs and UHMW polyurethane bearings. Both ends are greaseable and rebuildable. Fully assembled the RECOIL traction bars are 60" long and mount to the vehicle using fabricated 1/4" steel brackets.

The BDS spanner wrench for BDS Fox 2.5 Coil-overs features a unique design that uses a 1/2" ratchet or 1/2" breaker bar as the handle. Using a ratchet allows the spanner wrench to function in multiple positions making it much easier to use in tight IFS suspension setups. The spanner wrench is a pin-style design that is precision machined to fit in the Fox adjustment collar holes. This precise fit provides the best grip and reduces the chance of damage to the tool, adjustment collar, and your knuckles. The tool was designed for ease of use and includes user instructions.
