{"product_id":"heavy-duty-clutch-kit-3","title":"Heavy Duty Clutch Kit","description":"The ACT TC4-HDG6 is a Heavy Duty Race Sprung 6-Pad Clutch Kit engineered by Advanced Clutch Technology (ACT) for high-performance applications. This kit features ACT's renowned Heavy Duty pressure plate, distinguished by its exclusive diaphragm design that enhances clamp load, minimizes deflection, and extends clutch life. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring unparalleled durability and performance.\n\nThe kit includes a 6-pad, spring-centered race disc that is crucial for effectively damping torsional vibrations and withstanding the demands of aggressive driving and racing conditions. ACT's spring retainers are built with wraparound spring windows and thicker stampings for superior spring support, reduced stress concentration, and increased overall strength and reliability. This specific disc configuration results in a harsher engagement but allows for faster shifting. The 6-pad, spring-centered design is also recommended for larger clutch sizes due to its enhanced heat absorption capabilities.\n\nCarefully engineered and precisely assembled, this clutch kit is dynamically computer balanced to within .25 oz-in, surpassing the typical .50 oz-in balance of stock clutches, ensuring smooth operation across the entire RPM range and reliability at high speeds. It utilizes select ceramic friction materials, providing excellent heat tolerance and maximum performance. The engagement is characterized as aggressive with light to moderate pedal effort, and may produce OE to mild gear rattle. ACT specifies a break-in period of 300-500 miles for the organic street discs, emphasizing mild engagement during this phase to prevent overheating, hot spots, and glazing.\n\nThis clutch kit offers approximately 69% more torque capacity over OE specifications, with a rated capacity of 500 ft-lbs. It is recommended for high horsepower street or race use. The input shaft diameter is 1.125 inches, and the clutch disc diameter is 9.3 inches (236mm). The product weighs 15.0 lbs and comes with a 12-month warranty.","brand":"ACT","offers":[{"title":"Default Title","offer_id":52686759395640,"sku":"TC4-HDG6","price":610.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662145510.jpg?v=1784876407","url":"https:\/\/store.motormia.co\/products\/heavy-duty-clutch-kit-3","provider":"MOTORMIA","version":"1.0","type":"link"}
