Every diaphragm spring undergoes ACT's exclusive four-stage heat-treating process, and steel-backed friction plates with high-quality organic material deliver a stable friction coefficient, good heat capacity, and long clutch life. The friction plates transfer torque uniformly to a heat-treated chrome-moly Mono-Drive hub with one continuous spline, extending input shaft life while allowing quicker, trouble-free shifts. The kit includes a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, organic friction plates, rigid Mono-Drive hub, floater, patented Monoloc collar, release bearing, alignment tool, and pilot bearing if needed. Mod-Twin clutches are fully rebuildable and most components can be ordered separately.\u003c\/p\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/9aea4a88ee91500c37a766fcb5c28a21.PDF\"\u003eWarranty\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/faed19c181e50f728c396acdc81f7bbc.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTorque Capacity: 700 ft-lb\u003c\/li\u003e\n\u003cli\u003eClutch Disc Diameter: 8.8 in \/ 225mm (twin-disc)\u003c\/li\u003e\n\u003cli\u003eHub: Rigid Mono-Drive, chrome-moly\u003c\/li\u003e\n\u003cli\u003eDisc Material: Organic, steel-backed\u003c\/li\u003e\n\u003cli\u003eIncludes: Flywheel, pressure plate, twin organic discs, Mono-Drive hub, floater, Monoloc collar, release bearing, alignment tool, pilot bearing (if needed)\u003c\/li\u003e\n\u003cli\u003eRecommended Use: Street use\u003c\/li\u003e\n\u003cli\u003ePart Number: T1S-S07\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2004 Subaru Impreza WRX STI\u003c\/li\u003e\n\u003cli\u003e2005 Subaru Impreza WRX STI\u003c\/li\u003e\n\u003cli\u003e2006 Subaru Impreza WRX STI\u003c\/li\u003e\n\u003cli\u003e2007 Subaru Impreza WRX STI\u003c\/li\u003e\n\u003cli\u003e2007 Subaru Impreza WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2008 Subaru Impreza WRX STI\u003c\/li\u003e\n\u003cli\u003e2009 Subaru Impreza WRX STI\u003c\/li\u003e\n\u003cli\u003e2010 Subaru Impreza WRX STI\u003c\/li\u003e\n\u003cli\u003e2010 Subaru Impreza WRX STI Special Edition\u003c\/li\u003e\n\u003cli\u003e2011 Subaru Impreza WRX STI\u003c\/li\u003e\n\u003cli\u003e2011 Subaru Impreza WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2012 Subaru Impreza WRX STI\u003c\/li\u003e\n\u003cli\u003e2012 Subaru Impreza WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2013 Subaru Impreza WRX STI\u003c\/li\u003e\n\u003cli\u003e2013 Subaru Impreza WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2014 Subaru Impreza WRX STI\u003c\/li\u003e\n\u003cli\u003e2014 Subaru Impreza WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2015 Subaru WRX STI Base\u003c\/li\u003e\n\u003cli\u003e2015 Subaru WRX STI Launch Edition\u003c\/li\u003e\n\u003cli\u003e2016 Subaru WRX STI Base\u003c\/li\u003e\n\u003cli\u003e2016 Subaru WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2016 Subaru WRX STI Series.HyperBlue\u003c\/li\u003e\n\u003cli\u003e2017 Subaru WRX STI Base\u003c\/li\u003e\n\u003cli\u003e2017 Subaru WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2018 Subaru WRX STI Base\u003c\/li\u003e\n\u003cli\u003e2018 Subaru WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2018 Subaru WRX STI Type RA\u003c\/li\u003e\n\u003cli\u003e2019 Subaru WRX STI Base\u003c\/li\u003e\n\u003cli\u003e2019 Subaru WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2019 Subaru WRX STI S209\u003c\/li\u003e\n\u003cli\u003e2020 Subaru WRX STI Base\u003c\/li\u003e\n\u003cli\u003e2020 Subaru WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2021 Subaru WRX STI Base\u003c\/li\u003e\n\u003cli\u003e2021 Subaru WRX STI Limited\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis product can expose you to chemicals including carbon black, glass wool fibers, and silica (in clutch discs), chromium and nickel, which are known to the State of California to cause cancer or birth defects or other reproductive harm.
