All ACT diaphragms go through a four-stage heat-treating process, and precision cover stampings add rigidity and consistency to the pressure plate. Heavy Duty pressure plates increase clamp load by 20 to 50 percent over stock and are recommended for use with a street or race disc. The SB019 includes ACT's Monoloc, a one-piece, direct replacement for the standard two-piece wedge collar and wire ring used in pull-type clutches. Monoloc's segmented retaining ring tension is carefully calculated and tested to provide uniform loading on the bearing and pressure plate for consistent alignment, regardless of driver input or vehicle modifications, and its hardened chrome-moly steel construction is built to last.\u003c\/p\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/9aea4a88ee91500c37a766fcb5c28a21.PDF\"\u003eWarranty\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/d856e10aab4787d29e6c192d62ac3288.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePressure Plate Type: Heavy Duty, four-stage heat-treated diaphragm\u003c\/li\u003e\n\u003cli\u003eClamp Load: 20-50% increase over stock\u003c\/li\u003e\n\u003cli\u003eCover: Precision-stamped for rigidity and consistency\u003c\/li\u003e\n\u003cli\u003eRetaining Ring: ACT Monoloc, one-piece hardened chrome-moly (included)\u003c\/li\u003e\n\u003cli\u003eRecommended Use: Pair with a street or race disc\u003c\/li\u003e\n\u003cli\u003ePart Number: SB019\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\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\u003e2011 Subaru Impreza WRX STI\u003c\/li\u003e\n\u003cli\u003e2012 Subaru Impreza WRX STI\u003c\/li\u003e\n\u003cli\u003e2013 Subaru Impreza WRX STI\u003c\/li\u003e\n\u003cli\u003e2014 Subaru Impreza WRX STI\u003c\/li\u003e\n\u003cli\u003e2007 Subaru Impreza WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2011 Subaru Impreza WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2012 Subaru Impreza WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2013 Subaru Impreza WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2014 Subaru Impreza WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2010 Subaru Impreza WRX STI Special Edition\u003c\/li\u003e\n\u003cli\u003e2007 Subaru Legacy GT spec.B\u003c\/li\u003e\n\u003cli\u003e2008 Subaru Legacy GT spec.B\u003c\/li\u003e\n\u003cli\u003e2009 Subaru Legacy GT spec.B\u003c\/li\u003e\n\u003cli\u003e2015 Subaru WRX STI Base\u003c\/li\u003e\n\u003cli\u003e2016 Subaru WRX STI Base\u003c\/li\u003e\n\u003cli\u003e2017 Subaru WRX STI Base\u003c\/li\u003e\n\u003cli\u003e2018 Subaru WRX STI Base\u003c\/li\u003e\n\u003cli\u003e2019 Subaru WRX STI Base\u003c\/li\u003e\n\u003cli\u003e2020 Subaru WRX STI Base\u003c\/li\u003e\n\u003cli\u003e2021 Subaru WRX STI Base\u003c\/li\u003e\n\u003cli\u003e2015 Subaru WRX STI Launch Edition\u003c\/li\u003e\n\u003cli\u003e2015 Subaru WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2016 Subaru WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2017 Subaru WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2018 Subaru WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2019 Subaru WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2020 Subaru WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2021 Subaru WRX STI Limited\u003c\/li\u003e\n\u003cli\u003e2019 Subaru WRX STI S209\u003c\/li\u003e\n\u003cli\u003e2016 Subaru WRX STI Series.HyperBlue\u003c\/li\u003e\n\u003cli\u003e2018 Subaru WRX STI Type RA\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWarning: This product can expose you to chemicals including carbon black, glass wool fibers, or 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.
