McLeod Soft-Lok clutch assemblies are the most widely used of all their assemblies. These units are NHRA and IHRA record holders and meet the demands of the most powerful engines, while offering superb holding power and complete adjustability. The secret behind the McLeod Soft-Lok clutch assemblies is their low static pressure, which results in light pedal effort with soft clutch engagement. This allows a vehicle with up to 1,200 hp to leave the starting line harder without excessive tire spin, while maintaining enough holding power for the rest of the run.
