The McLeod Soft Lok assembly is the most widely used McLeod clutch for drag racers. This unit is NOT recommended for street use. As a NHRA and IHRA record holder, this assembly has low static pressure for a light pedal effort and soft clutch engagement. This unit leaves the starting line harder with less tire spin. The Soft Lok is equipped with adjustable spring pressure and is available with counterweights. Included is a pressure plate, sintered iron disc, and aluminum flywheel.
