Each diaphragm spring is treated through ACT’s exclusive four-stage heat-treating process to ensure consistent performance under high stress. Precision cover stampings provide added rigidity and reliability for long-term durability.\u003c\/p\u003e \u003cp data-start=\"675\" data-end=\"1096\"\u003eAt the heart of this kit is ACT’s 6-pad, spring-centered race disc, engineered to damp torsional vibrations and resist failure under demanding driving conditions. Reinforced spring retainers with wraparound windows and thicker stampings enhance strength and reduce stress concentrations. This configuration offers aggressive engagement and faster shifting, ideal for high-horsepower street or race applications.\u003c\/p\u003e \u003cp data-start=\"1098\" data-end=\"1415\"\u003eThe included Monoloc upgrade replaces the traditional two-piece wedge collar and wire ring used in pull-type clutches. Built from hardened chrome-moly steel, the Monoloc ensures uniform bearing load, improved alignment, and extended release mechanism life — even under aggressive driving or modified setups.\u003c\/p\u003e \u003cp data-start=\"1422\" data-end=\"1439\"\u003e\u003cstrong data-start=\"1422\" data-end=\"1437\"\u003eSpecs\u003c\/strong\u003e\u003c\/p\u003e \u003cul data-start=\"1440\" data-end=\"1715\"\u003e \u003cli data-start=\"1440\" data-end=\"1489\"\u003e \u003cstrong data-start=\"1442\" data-end=\"1462\"\u003eTorque Capacity:\u003c\/strong\u003e 668 ft-lbs (88% over OE)\u003c\/li\u003e \u003cli data-start=\"1490\" data-end=\"1520\"\u003e \u003cstrong data-start=\"1492\" data-end=\"1510\"\u003eDisc Material:\u003c\/strong\u003e Ceramic\u003c\/li\u003e \u003cli data-start=\"1521\" data-end=\"1559\"\u003e \u003cstrong data-start=\"1523\" data-end=\"1541\"\u003eDisc Diameter:\u003c\/strong\u003e 9.4 in \/ 240 mm\u003c\/li\u003e \u003cli data-start=\"1560\" data-end=\"1594\"\u003e \u003cstrong data-start=\"1562\" data-end=\"1587\"\u003eInput Shaft Diameter:\u003c\/strong\u003e 1 in\u003c\/li\u003e \u003cli data-start=\"1595\" data-end=\"1634\"\u003e \u003cstrong data-start=\"1597\" data-end=\"1621\"\u003ePressure Plate Type:\u003c\/strong\u003e Heavy Duty\u003c\/li\u003e \u003cli data-start=\"1635\" data-end=\"1659\"\u003e \u003cstrong data-start=\"1637\" data-end=\"1648\"\u003eWeight:\u003c\/strong\u003e 18.5 lbs\u003c\/li\u003e \u003c\/ul\u003e \u003cp data-start=\"1722\" data-end=\"1755\"\u003e\u003cstrong data-start=\"1722\" data-end=\"1753\"\u003ePerformance Characteristics\u003c\/strong\u003e\u003c\/p\u003e \u003cul data-start=\"1756\" data-end=\"2384\"\u003e \u003cli data-start=\"1756\" data-end=\"1876\"\u003e \u003cstrong data-start=\"1758\" data-end=\"1767\"\u003eFeel:\u003c\/strong\u003e Light to moderate pedal effort, aggressive engagement, OE to mild gear rattle, confident high-RPM shifting\u003c\/li\u003e \u003cli data-start=\"1877\" data-end=\"1991\"\u003e \u003cstrong data-start=\"1879\" data-end=\"1888\"\u003eLife:\u003c\/strong\u003e Extended clutch and release mechanism life thanks to ACT’s diaphragm design and Monoloc construction\u003c\/li\u003e \u003cli data-start=\"1992\" data-end=\"2124\"\u003e \u003cstrong data-start=\"1994\" data-end=\"2006\"\u003eQuality:\u003c\/strong\u003e Precision-engineered and balanced with premium ceramic friction materials for maximum heat tolerance and durability\u003c\/li\u003e \u003cli data-start=\"2125\" data-end=\"2189\"\u003e \u003cstrong data-start=\"2127\" data-end=\"2147\"\u003eRecommended Use:\u003c\/strong\u003e High-horsepower street or race vehicles\u003c\/li\u003e \u003cli data-start=\"2190\" data-end=\"2384\"\u003e \u003cstrong data-start=\"2192\" data-end=\"2211\"\u003eACT Difference:\u003c\/strong\u003e Every kit is 100% clamp-load tested and dynamically computer balanced for smooth, reliable performance — featuring ACT’s patented Monoloc for superior release consistency\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e: Legacy GT Spec.B models will need to use the STI flywheel in order to use this clutch.\u003c\/p\u003e","brand":"ACT","offers":[{"title":"Default Title","offer_id":50501053939998,"sku":"actSB10-HDG6","price":1257.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0846\/6730\/2174\/files\/act-heavy-duty-6-puck-disc-clutch-kit-2004-2021-sti-2007-2009-lgt-spec-b-sb10-hdg6-373495.jpg?v=1768061165","url":"https:\/\/subistyle.ca\/products\/act-heavy-duty-6-puck-disc-clutch-kit-2004-2015-sti-2007-2009-lgt-spec-b-sb10-hdg6","provider":"Subistyle","version":"1.0","type":"link"}
