Performance Features
The GM3-HDG6 kit features ACT's renowned Heavy Duty pressure plate, which utilizes an exclusive diaphragm design.

Each diaphragm undergoes a rigorous four-stage heat-treating process, enhancing performance and longevity.
ACT’s 6-pad, spring-centered race disc is engineered to dampen torsional vibrations while resisting failure under extreme conditions. The engagement is more aggressive, allowing for quicker shifts, making it perfect for those who appreciate the thrill of high-performance driving.
