ACT-Advanced Clutch Technology

Advanced Clutch Technology designs, engineers and develops products by leveraging decades of track and performance street experience. Advanced CAD, FEA simulation and CAM tools help ensure highly optimized performance, reliability and repeatability. These key advantages are produced by combining the best engineering and design methodologies with the latest in materials and manufacturing techniques.


ACT Clutch Kits stand unequaled in terms of consistent pedal feel, high torque capacity, long wear life and durability. In-house manufacturing is critical in tuning components specifically to each individual application, while maintaining the predictable ACT pedal feel across the entire catalog.

XACT Flywheels
Flywheels for both performance and racing are weight optimized for an ideal balance of Moment of Inertia (MOI = resistance to acceleration) and strength. ACT uses one-piece Chromoly steel forgings, the strongest manufacturing method available, to best align the internal grain structure. Streetlite versions are configured for a significant performance boost with minimal drivability compromise. Offered for select applications, Prolite flywheels are aggressively tuned for competition use. These rival the MOI of the lightest aluminum flywheels without any of the potential reliability or maintenance concerns.
