One of the most important roles in the drivetrain is the clutch. As power is increased, the clutch begins to struggle to put the power down. Stronger single disk clutches exist and will be able to hold massive amounts of power. However, it becomes harder and harder to drive as well. With this in mind, ACT released twin plate clutches to provide an alternative to the standard clutch. Twin disc clutches provide a system that allows you to have a lot of power, but still allow you to drive it as a normal daily driver. With kits being purpose built for either street or track use. Each kit will also includes a StreetLite or ProLite flywheel as well!

ACT Twin Disc Clutch Design Types:

• Standard: All ACT Twin Disc kits include a CNC-machined and dynamically balanced flywheel to ensure trouble-free installation and operation. The pressure plate has multiple clamp loads for different situation. Each kit is also fully serviceable and rebuildable.
• Sintered Iron: Includes all the same parts and features as the Standard kits but are uniquely designed with special heat treated discs. This increases heat resistance and allows for very strong clamping loads and engagement. These kits will also have 10% - 20% stiffer pedal feel. Specifically designed to be able to take a lot of abuse.
• MOD: Includes all the same parts and features as the Standard kits but with a new modular design. These kits use a unique central hub (mono drive) design. While with most clutches the discs have the splines for the input shaft, these kits have the disc splined to fit the central hub. This design reduces weight, size, and failure points. It also allows you to switch out discs at a later point (email us for details).

ACT builds multiple types and styles of twin disc clutches that are suited for different situations. Please ensure to double check each kit to ensure it meets your specific needs.

ACT Twin Disc Clutch Clutch Performance Levels:
