Fox Racing Shocks 981-25-604-3 Factory Race 2.5x10 Coilover Internal Bypass Rotating Remote Reservoir Shock with DSC Adjuster

The Fox Racing Shocks 981-25-604-3 is a Factory Race Series 2.5-inch diameter, 10-inch stroke coilover (C/O) shock absorber featuring an Internal Bypass design with a Rotating Remote Reservoir and DSC (Dual Speed Compression) Adjuster. Built for serious off-road racing and high-performance applications, this shock delivers precise, tunable damping control in the most demanding conditions.
