The McLeod Soft-Lok assembly is the most widely used McLeod clutch assembly for drag racers, and is not recommended for street use. This unit is an NHRA & IHRA record holder and meets the demands of the most powerful engines while offering superb holding power and complete adjustability. The secret behind the Soft-Lok is low static pressure, resulting in light pedal effort with soft clutch engagement. This allows the vehicle with up to 1200 HP to leave the starting line harder without excessive tire spin yet still maintain enough holding power for the rest of the run. Adjustable spring pressure allows you to"dial in" the clutch for your vehicle and engine along with the ability to add counter weights to increase the holding power at higher RPM's.
Kit includes Pressure Plate, Sintered Iron Disc & Aluminum Flywheel.

Note: The kits listed below are for use with a 11" disc and Ford long pressure plate. The pressure plate bolt circle is 3-3/8" spread center to ceneter.
