ACT carefully selects the right amount of cushioning between the linings to allow for good engagement characteristics without sacrificing performance. |
 |
 |
Most ACT spring centered assemblies use bushings and cone springs similar to factory clutch discs. This creates frictional dampening which improves clutch life and reduces noise. |
|
 |
Spring retainers by ACT utilize a wrap around spring window that not only gives liberal support for the springs, but also reduces stress concentrations that are a common cause for failure. (Offered on most ACT Modified and Performance Street Discs) |
|
 |
ACT performance linings are steel backed for maximum burst and rotational strength. |
|
 |
We carefully broach our splines to ensure exact fit onto transmission input shaft for long spline life and better clutch release. |
|
 |
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. |
|
 |
ACT Performance Street Discs feature a high copper content friction material. Through the use of copper the heat is pulled away from the surface. ACT achieves better heat tolerance and faster recovery from overheating. |
|
 |
Top grade rivets are used to securely fasten the part together. Rivet design and rivet materials are carefully selected for maximum strength. |
|
 |
Spring windows on most ACT street discs are heat treated to resist wear, increase strength and reduce the chance of springs “popping” out. |
|
 |
ACT provides thicker retainer stampings for increased strength and reliability. (Offered on most ACT Modified and Performance Street Discs) |
|
 |
All modified, performance and many standard replacement discs are certified as meeting SFI Specification 1.1 and are legal in all racing organizations that require SFI certification. |
|
 |
Precision stampings for disc components are manufactured using dedicated tooling. This allows ACT to offer the highest in quality and consistency. |
