The ACT TC3-HDSS kit is engineered for those seeking a robust upgrade for their clutch system. This kit combines ACT's most popular Heavy Duty pressure plate with a premium street disc, providing a reliable solution for both daily driving and spirited performance.
The Heavy Duty pressure plate utilizes an exclusive diaphragm design that enhances clamp load while minimizing deflection. This results in improved clutch life and performance. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring optimal durability and performance under demanding conditions. The precision cover stampings contribute to the rigidity and consistency of the pressure plate, further enhancing its reliability.
ACT's Performance Street disc is constructed with high copper content organic materials, promoting efficient heat transfer. The steel-backed lining offers increased burst strength and durability, making it suitable for both street and racing applications. With reduced marcel, this disc allows for quicker shift action, complementing the performance characteristics of the Heavy Duty pressure plate.
