Fox 2.5 Series Coilovers

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 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 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.
