Product Details

Advanced Clutch Technology has specialized in performance clutches and flywheels for sport compacts, domestic cars, and diesel tucks since 1994. With focus on ensuring that their parts are perfect for any need and accurately described, showing any and all possible specifications, ACT is one of the leading clutch engineers in the market today. 

Every design is thoroughly researched and tested prior to release to guarantee their products meet and exceed the customer's expectations. Careful attention is payed to factors such as engine torque, maximum RPM, drive type (FWD, RWD, AWD), and the type of driving being done, such as street, sport, track events, racing, etc. ACT's clutch kits are competitively priced, often with  specifications greater than competitor's and at a higher quality.

This clutch kit features a Heavy Duty pressure plate and an R4 racing clutch disc.

Their Heavy Duty pressure plate offers a 20-50% clamp load increase, stock to moderate pedal feel, and can be used for either street or racing applications. All diaphragms went through a four stage heating process for increased strength and unparalleled performance.

The R4 clutch disc is an unsprung, rigid 4-pad racing disc that is recommended for drag and road racing. Its material composition is high quality, ceramic friction materials and a chrome-moly hub that has been heat treated for high strength. 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, but a shortened spline life but a fast, aggressive engagement in comparison to standard street-use clutch discs.
