As every driver, engine, and application is different, ACT offers a variety of complete clutch kits. ACT clutch kits include the pressure plate, disc, release bearing, and (in most cases) pilot bearing and alignment tool. For street use, you will need a long lasting clutch that has positive feel, smooth engagement and quiet operation. For racing, you need a tough clutch that will enable quick shifts and hard slips all the way to the finish line.
