The ACT HA1-HDG6 kit is engineered for those looking to enhance their clutch performance with a heavy-duty solution. This kit features ACT's renowned Heavy Duty pressure plate, which employs a unique diaphragm design that significantly increases clamp load while minimizing deflection. This design not only maximizes clutch life but also ensures consistent performance under demanding conditions.
Each diaphragm undergoes a rigorous four-stage heat-treating process, providing exceptional durability and performance. The precision cover stampings of the pressure plate enhance rigidity, ensuring reliable engagement and disengagement during operation. The 6-pad, spring-centered race disc is designed to effectively dampen torsional vibrations, making it ideal for both street and race applications.
