In vehicles with engines with high engine torque the return time of the clutch pedal may be too short. This means that the torque peak is so high that it can damage the driveline.

In the event of the torque peak being to high, the hydraulic flow in the engagement direction is choked between the concentric slave cylinder (CSC) and the master cylinder using a shock load limiter.
