The ACT T1S-D03 Twin Disc Heavy Duty Street Clutch Kit doubles the number of friction surfaces compared to a single-disc setup, increasing wear resistance, heat capacity, and service life. A proprietary Positive Lift Floater System delivers quiet operation with no floater rattle and no posts to wear. Every diaphragm undergoes ACT's exclusive four-stage heat-treating process, and the twin-disc design allows for adjustment to disc wear while maintaining equal disengagement between discs. The Performance street rigid-hub discs use premium organic friction material with high copper content for improved heat transfer, plus steel-backed lining for greater burst strength and durability. A heat-treated chrome-moly hub and carefully selected rivet design and materials maximize strength. Each kit includes a CNC-machined, dynamically balanced flywheel for trouble-free installation, and is recommended for high-horsepower street or race use.
