The extreme performance demands required of today's performance cars coupled with an aggressive clutch can cause extreme driveline shock loads. The Clutch Masters FCV-2000 (Flow Control Valve) will help reduce shock loads by allowing the clutch to slip slightly during engagement. This is accomplished by precisely controlling the return flow of the hydraulic fluid by selecting one of three control jets. This device will not restrict flow during disengagement and as such, under normal driving conditions the pedal release and engagement will not feel different.
