These ACT heavy-duty (HD) clutch kits offer a clamp load increase of 20 to 50 percent, increasing torque capacity. The pedal feels stock to moderate with these clutches. Many are SFI-certified to ensure safety.
- Premium ceramic friction materials provide high-heat tolerance, high coefficient of friction and low wear rates.
- All friction pads are measured, sorted and matched before assembly to ensure that each disc is uniform in thickness.
- Carefully broached splines to ensure exact fit onto the transmission input shaft for long spline life and better clutch release.
- ACT provides thicker retainer stampings for increased strength and reliability.
- Top grade rivets are used to securely fasten the part together. Rivet design and rivet materials are carefully selected for maximum strength.
- ACT spring retainers feature wraparound spring windows that provide support and reduce stress concentrations, which are common causes of failure.
- Heavy duty torsional dampening springs are stronger in most cases than standard springs and are provided in the best sizes and spring rates to suit the application.
- All drive plates consist of high-carbon spring steel that is heat-treated and black zinc-plated to resist bending, cracking, fatiguing and rusting, even under severe racing conditions.
- Precision stampings for disc components are manufactured using dedicated tooling. This allows ACT to offer the highest in quality and consistency.
- Most spring-centered assemblies use bushings and cone springs to create frictional dampening, which reduces noise and extends clutch life.
- All race discs are certified as meeting SFI Specification 1.1 and are legal in all racing organizations that require SFI certification.
