2001-2010 Duramax 4.5" Coilover Lift Kit (BDS740FDSC)

If you've got an HD Duramax truck it's possible it could use some new suspension! Why not lift it while you're in there with this BDS 4.5" Coilover conversion system. This system eliminates your torsion bars and gives you a much more adjustable alternative. This system builds on the BDS high clearance system design offering more ground clearance, corrects suspension, steer, driveline geometry, and pairs it with the race-proven pedigree of Fox 2.5 factory series Coilovers to soak up the harshest terrain while still offering comfort and control for your daily commute.

Fox 2.5 Remote Reservoir Coilovers w/ DSC

These race-proven FOX 2.5 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 these FOX coilovers are designed to take all the guesswork out of setting your vehicle up and are designed to be used with BDS lift systems. These have the added benefit of DSC (dual speed compression) adjustment for easy-to-use high-speed and low-speed compression tuning build into the end of the reservoir to dial in the performance for various terrains. 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 DSC external remote reservoir to improve damper capability across any terrain.
