Fox 2.5 Internal Bypass Coilovers with DSC come pre-tuned from AccuTune Off-Road and are available with a remote reservoir or piggy back. The Fox Dual Speed Compression Adjuster (DSC) makes tuning these shocks much easier because you no longer have to rely on the bypass for low speed and high speed compression. Fox 2.5 Internal Bypass Coilovers offer bypass performance in a coilover package. Fox Internal Bypass Coilovers use a unique design that allows for a high flow piston and tube with reed valves to provide position sensitive damping – just like a 3-tube bypass shock. Whether your limited by class rules or space constraints, Fox 2.5 Internal Bypass Coilovers deliver the performance you need.
