ACT Performance clutch is recognized as a leader in high performance clutch solutions. Every ACT clutch is designed to be a bolt-on solution and will utilize all factory alignment tools and mounting points. ACT clutches are engineered and assembled in America with the highest level of manufacturing and quality control standards. When choosing a clutch you want to make sure you select the correct clutch for your application. For example, race clutches can often times be too aggressive for the street causing the user to have difficulty starting and operating the clutch while driving. For most applications STILLEN recommends ACT’s “street discs.” These clutches can hold more power than the factory units while still offering streetable driving characteristics. If your car produces significantly more power than factory or you are using the car for racing purposes we would recommend upgrading to a full race “puck” clutch. 

ACT aims to provide the best pedal feel, raised torque capacity and extended wear life. STILLEN and ACT have been working together for more than 2 decades to offer superior clutch products to our customers.

T1R-G09 twin disc kit offers twice the number of disc surfaces for better wear, heat capacity and long life compared to single disc kits. These kits use a proprietary Positive Lift Floater System design, which results in quiet operation with no floater rattle and no posts to wear. ACT twin disc kits endure an exclusive four-stage, heat treating process performed on all diaphragms. The ACT twin disc features the ability to adjust for disc wear and provides equal disengagement for discs. ACT’s 6-pad rigid race discs are made with high quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and trouble-free service. All ACT twin disc kits include a CNC-machined and dynamically balanced flywheel to ensure trouble-free installation and operation. ACT twin disc kits include a pressure plate, two discs, a floater, flywheel and alignment tool. Some kits may include a pilot bearing and release bearing.
