The ACT TS5-HDSD kit is designed for those who demand durability and performance from their clutch system. This kit features ACT's renowned Heavy Duty pressure plate, which utilizes an exclusive diaphragm design to enhance clamp load, minimize deflection, and extend clutch life. Each diaphragm undergoes a meticulous four-stage heat-treating process, ensuring exceptional performance under pressure.
ACT pressure plates are engineered with precision cover stampings, providing the necessary rigidity and consistency for reliable operation. This heavy-duty setup is complemented by performance street rigid-hub discs made from premium organic materials that boast a high copper content, improving heat transfer. The steel-backed lining enhances burst strength and durability, making it suitable for both street and race applications.
The chrome-moly hub is heat-treated for added strength, while the rivet design and materials are selected to maximize durability. Weighing in as the minimum weight street disc, the TS5-HDSD allows for quicker shifts without sacrificing reliability. This rigid-hub disc is engineered for race-proven performance while maintaining street manageability.
