Fox 2.5 Performance Series Remote Reservoir coilovers with DSC Adjusters from AccuTune Off-Road come pre-tuned for your ride, your terrain, and your driving style. The standard Fox shock valving is not well tuned for most vehicles and will cause harshness and bucking off-road. We custom tune every Fox Performance Series 2.5 Remote Reservoir Coilover shock using AccuTune Equations, and AccuTune Double Flutter Stacks to give you the best performance possible.
