Key Features

This clutch disc features a carefully engineered design focused on durability, responsiveness, and smooth engagement. Its construction includes high-quality organic friction materials with high copper content, which helps dissipate heat effectively during aggressive driving. The disc incorporates a reduced marcel, enabling faster shift action to complement ACT pressure plates, resulting in quicker, more precise gear changes. ACT’s spring-centered assemblies utilize bushings and cone springs similar to factory clutch discs, providing effective frictional dampening to minimize driveline shock and chatter. The overall design aims to deliver a reliable, high-performance clutch experience suitable for daily driving and moderate performance applications.
