T1R-D03 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.  
Since 1994, Advanced Clutch Technology has specialized in performance clutches and flywheels. All products are made from the highest quality materials and then necessarily tested to ensure they perform to the customers' expectations.
