They can survive extreme racing use without requiring additional pedal effort from the user. Dragon Claw Clutch Kits use a diaphragm plus patented lever assist combination. The diaphragm keeps the pedal effort near stock for street use. The levers swing out by centrifugal force as engine RPM increases and apply direct pressure above the pressure plate. This results in a clamping force that holds under conditions where many of the competitor’s “high end” clutches fail.
