ACT TK1-HDG4 Heavy Duty/Race Sprung 4 Pad Kit

The ACT TK1-HDG4 kit is designed for those who demand performance and reliability 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 the overall lifespan of your clutch. With a rigorous four-stage heat-treating process, each diaphragm is crafted for exceptional performance under pressure.

One of the standout features of the TK1-HDG4 is its precision cover stampings, which ensure rigidity and consistency. The kit also includes a 4-pad spring-centered race disc that effectively dampens torsional vibrations, resulting in quieter operation and improved durability, even in the most demanding environments. Customers have noted that while engagement can be harsher, the benefit is noticeably quicker shifting, making it a favorite for both street and race applications.
