The forging is heat-treated for strength and toughness, and the ring gear is induction-hardened for maximum service life. One-piece construction eliminates the failure points found in multi-piece flywheels and provides uniform, efficient heat transfer away from the clutch disc, so there are no warped inserts or loose ring gears to deal with. Each flywheel is forged, CNC-machined, and dynamically computer-balanced for smooth, reliable operation at high RPM.\u003c\/p\u003e\u003cp\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\u003c\/p\u003e\u003cp\u003eBacked by ACT's one-year \"Excellence in Performance\" warranty.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eProduct Type: XACT Flywheel Streetlite\u003c\/li\u003e\n\u003cli\u003eWeight: 16.5 lbs (approx. 25% lighter than stock)\u003c\/li\u003e\n\u003cli\u003eConstruction: One-piece forged, CNC-machined, dynamically computer-balanced\u003c\/li\u003e\n\u003cli\u003eRing Gear: Induction-hardened for extended service life\u003c\/li\u003e\n\u003cli\u003eHardware: Flywheel bolts included (M12-1.5 x 25mm)\u003c\/li\u003e\n\u003cli\u003eRecommended Use: Street and race\u003c\/li\u003e\n\u003cli\u003eGear Rattle: OE to mild\u003c\/li\u003e\n\u003cli\u003ePart Number: 601170\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eVehicle Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e2008 BMW 128i\u003c\/li\u003e\n\u003cli\u003e2009 BMW 128i\u003c\/li\u003e\n\u003cli\u003e2010 BMW 128i\u003c\/li\u003e\n\u003cli\u003e2011 BMW 128i\u003c\/li\u003e\n\u003cli\u003e2012 BMW 128i\u003c\/li\u003e\n\u003cli\u003e2013 BMW 128i\u003c\/li\u003e\n\u003cli\u003e2006 BMW 325i\u003c\/li\u003e\n\u003cli\u003e2006 BMW 325xi\u003c\/li\u003e\n\u003cli\u003e2007 BMW 328i\u003c\/li\u003e\n\u003cli\u003e2008 BMW 328i\u003c\/li\u003e\n\u003cli\u003e2009 BMW 328i\u003c\/li\u003e\n\u003cli\u003e2010 BMW 328i\u003c\/li\u003e\n\u003cli\u003e2011 BMW 328i\u003c\/li\u003e\n\u003cli\u003e2012 BMW 328i\u003c\/li\u003e\n\u003cli\u003e2013 BMW 328i\u003c\/li\u003e\n\u003cli\u003e2009 BMW 328i xDrive\u003c\/li\u003e\n\u003cli\u003e2010 BMW 328i xDrive\u003c\/li\u003e\n\u003cli\u003e2011 BMW 328i xDrive\u003c\/li\u003e\n\u003cli\u003e2012 BMW 328i xDrive\u003c\/li\u003e\n\u003cli\u003e2013 BMW 328i xDrive\u003c\/li\u003e\n\u003cli\u003e2007 BMW 328xi\u003c\/li\u003e\n\u003cli\u003e2008 BMW 328xi\u003c\/li\u003e\n\u003cli\u003e2006 BMW 330i\u003c\/li\u003e\n\u003cli\u003e2006 BMW 330xi\u003c\/li\u003e\n\u003cli\u003e2006 BMW 525i\u003c\/li\u003e\n\u003cli\u003e2007 BMW 525i\u003c\/li\u003e\n\u003cli\u003e2006 BMW 525xi\u003c\/li\u003e\n\u003cli\u003e2007 BMW 525xi\u003c\/li\u003e\n\u003cli\u003e2008 BMW 528i\u003c\/li\u003e\n\u003cli\u003e2009 BMW 528i\u003c\/li\u003e\n\u003cli\u003e2010 BMW 528i\u003c\/li\u003e\n\u003cli\u003e2008 BMW 528xi\u003c\/li\u003e\n\u003cli\u003e2006 BMW 530i\u003c\/li\u003e\n\u003cli\u003e2007 BMW 530i\u003c\/li\u003e\n\u003cli\u003e2006 BMW 530xi\u003c\/li\u003e\n\u003cli\u003e2007 BMW 530xi\u003c\/li\u003e\n\u003cli\u003e2007 BMW X3 3.0si\u003c\/li\u003e\n\u003cli\u003e2008 BMW X3 3.0si\u003c\/li\u003e\n\u003cli\u003e2009 BMW Z4 sDrive30i\u003c\/li\u003e\n\u003cli\u003e2010 BMW Z4 sDrive30i\u003c\/li\u003e\n\u003cli\u003e2011 BMW Z4 sDrive30i\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003ch5\u003eWhat does the ACT 601170 flywheel fit?\u003c\/h5\u003e\u003cp\u003eThe 601170 fits the 2008-2013 BMW 128i (E82\/E88) with the N51\/N52 L6-3.0L engine, plus a range of other N51\/N52-powered 3-series, 5-series, X3, and Z4 models sharing the same clutch spline.
