At ACT our best customers are people that know what they are buying and why. Every clutch design has benefits and tradeoffs so explore all the resources available to make the best choice for you.
Most performance enthusiasts relate more to horsepower rather than torque, but clutch capacity is best measured in terms of torque. Think in terms of comparing a high rpm 250hp Honda Civic versus a Dodge Cummins turbo diesel which has the same horsepower. The diesel will need about three times the clutch capacity because the engine produces about three times the torque. We started rating our clutches years ago so people will have an honest estimate of what to expect. We provide the percentage of clamp load increase and the estimated torque capacity right on our application chart.
Take a look at the graph and you will see that our pressure plates will provide a higher clamp load for a longer distance than our typical competitor. This exclusive ACT design translates into longer clutch life, a more positive feel and better shifting. There will be an increase in pedal effort ranging from slight to heavy depending on application.

ACT clutches and flywheels offer proven performance for both street and full race applications. ACT employs vehicle testing, dynamometer results, laboratory testing, and the latest in CAD, 3D modeling, and FEA (Finite Element Analysis) software to develop many of their products long before they come to market. There is no guesswork and very few surprises.

Calculated results are given for each clutch by publishing the increase in clamp load and estimated torque capacity in our catalog and on our website. These are not mere marketing claims, but accurate estimates based from solid engineering principles, confirming what we already know from the track. Each pressure plate is load tested and cycled to ensure parts meet ACT's strict quality standards.

Extra steps are taken with virtually every ACT part to provide added value. Some of these steps include improved designs, hardening on critical wear points, computer balancing and SFI certification. ACT products not only out perform the competition, but out last them as well. Rather than take shortcuts to cut cost, we insist on quality. ACT adds value that you may not initially notice, but you will appreciate thousands of miles later.

ACT designs and manufactures their parts using unique engineering ideas that include proprietary trade secrets. This is especially true when it comes to diaphragm spring technology and what separates ACT from other brands. As a result, ACT clutches are unequaled for their consistent feel, high torque capacity, good durability and long wear life.
