Manufactured by LuK — a Schaeffler Group brand and globally recognized leader in clutch system technology — this slave cylinder delivers reliable hydraulic actuation for smooth, consistent clutch engagement and disengagement.

The clutch slave cylinder plays a critical role in the hydraulic clutch system, converting hydraulic pressure from the master cylinder into mechanical force to disengage the clutch.
