Advanced Clutch Technology (ACT) 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.

This clutch kit features an Xtreme pressure plate, a G6 racing clutch disc, and an XACT Streetlite Flywheel.

Their Xtreme pressure plate offers a 50-120% clamp load increase, moderate to heavy pedal feel, and is recommended for high performance street and racing applications. All diaphragms went through a four stage heating process for increased strength and unparalleled performance.

The G6 clutch disc is a sprung, 6-pad racing disc that is recommended for high horsepower street and race us and is better at handling high heat than the 4-pad disc. Its material composition is high quality, ceramic friction materials and a heavy duty torsional dampening springs that are rate for this clutch disc's size and expected uses. It has an increased torque capacity, and is better for faster shifting with its low weight and inertia. Being a racing disc, it has good durability and its ceramic composition allows for high heat tolerances. It also has a fast, aggressive engagement in comparison to standard street-use clutch discs.

The final main component is the XACT Streetlite Flywheel. This option is the most popular thanks to it versatility for street driving and drag/track style racing, its lighter weight for increased throttle response, and its single mass design.

This clutch kit features a Heavy Duty pressure plate and a G6 racing clutch disc.

The heavy duty pressure plate included offers a 20-50% clamp load increase, stock-moderate pedal feel, and heat treated diaphragms for increased strength and performance.

Next in this kit is the G6 racing clutch disc. This disc is a sprung, 6-pad disc that is suited for high horsepower road and track style racing and is also better at handling higher heat versus the 4-pad version of this disc, the G4. The G6 pads are composed of ceramic friction materials and the disc has a chome-moly hub that is heat treated for additional strength under high load engagements. Also featured are heavy duty torsional springs that are rated for the clutch kit's expected uses. Over stock, this clutch kit has a much higher torque capacity and is better for quick shifting thanks to lower weight and inertia. Despite its ceramic racing style pads, this disc has great durability. In turn, these pads provide higher heat tolerances and faster, more aggressive clutch engagements.
