The ACT TY4-HDSS kit combines advanced engineering with robust materials to deliver a reliable clutch solution for performance-oriented driving. This kit features ACT's renowned Heavy Duty pressure plate and a performance street disc, designed for those who demand durability and responsiveness from their drivetrain components.
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 under stress. Each diaphragm undergoes a rigorous four-stage heat treatment process, ensuring it can withstand high temperatures and maintain its integrity during aggressive driving conditions. Precision cover stampings contribute to the plate's rigidity and consistency, making it a reliable choice for both street and light track use.
The performance street disc is constructed from premium organic materials, featuring a high copper content that improves heat transfer. This disc is equipped with a steel-backed lining for enhanced burst strength and durability. With a reduced marcel, the disc allows for quicker shift action, complementing the pressure plate's design for a seamless driving experience.
