You save % ()
This ACT clutch kit includes a Heavy Duty pressure plate, Performance Street disc, release bearing, pilot bearing and alignment tool. The Heavy Duty pressure plate allows for a 20 to 50 percent increase in clamp load over the stock unit. ACT's Heavy Duty pressure plate features precision CNC machined parts, drive straps and rivets to securely locate contact face to the cover for quiet, trouble-free operation. The Heavy Duty pressure plate will have a stock to moderate pedal feel.
ACT pressure plates feature creative diaphragm designs to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure an exclusive four-stage, heat-treating process for unparalleled performance.The Heavy Duty pressure plate meets SFI Specification 1.1.
ACT Performance Street discs are modified with reduced marcel for faster shift action to complement ACT pressure plates. Performance Street discs have higher copper content friction lining for heat tolerance and steel-backed lining for greater burst strength and durability. Also, they feature top grade rivets to securely fasten the part together. The rivet design and rivet materials are carefully selected for maximum strength. ACT spring-centered assemblies use bushings and cone springs similar to factory clutch discs. This creates frictional dampening, which improves clutch life and reduces noise. All Performance Street discs are certified as meeting SFI Specification 1.1 and are legal in all racing organizations that require SFI certification. The kit is completed with a quality, stock replacement release bearing, pilot bearing and alignment tool.
