The ACT AA5-HDG6 kit is engineered for high-performance applications, featuring a Heavy Duty pressure plate that stands out in the aftermarket scene. This kit utilizes an exclusive diaphragm design that enhances clamp load, minimizes deflection, and ultimately extends clutch lifespan. Each diaphragm undergoes a rigorous four-stage heat treatment process, ensuring exceptional durability and performance under demanding conditions.
ACT's precision-engineered pressure plates are constructed with rigid cover stampings, providing consistent performance. The 6-pad, spring-centered race disc is designed to dampen torsional vibrations effectively, making it suitable for high-stress environments. The spring retainers feature wraparound spring windows and thicker stampings, which not only support the springs but also enhance strength and reliability.
This kit includes a flywheel and necessary bolts for installation. It requires the use of the ACT flywheel provided in the kit. Flywheel bolts (M10-1.0 X 22mm) and pressure plate bolts (M8-1.25 X 20mm) are included. Please note that this is a single mass conversion kit, and the clutch master cylinder and slave cylinder are not included.
