ACT BM12-HDR6 Heavy Duty/Race Rigid 6 Pad Kit

The ACT BM12-HDR6 kit is engineered for serious performance applications, featuring a Heavy Duty pressure plate that stands out in the competitive landscape of aftermarket clutches. This kit employs an exclusive diaphragm design that enhances clamp load while minimizing deflection, ensuring optimal clutch life even under demanding conditions.

Construction and Materials

Each diaphragm undergoes a meticulous four-stage heat-treating process, resulting in exceptional performance and durability. The pressure plates are crafted with precision cover stampings that provide enhanced rigidity and consistency. The included 6-pad rigid race discs utilize high-quality ceramic friction materials, which are known for their ability to withstand high temperatures and deliver reliable performance.
