Featuring ACT's most popular heavy-duty pressure plate, this kit offers a significant upgrade over stock components with enhanced clamp load and durability. The pressure plate employs an exclusive diaphragm design, which increases clamp force, reduces deflection, and extends the clutch's lifespan. Crafted through a four-stage heat-treating process, the diaphragm ensures unparalleled performance and reliability. Precision cover stampings contribute to the rigidity and consistency of the assembly, providing smooth engagement and improved pedal feel. The kit's street rigid-hub disc utilizes premium organic friction materials with high copper content, ensuring superior heat transfer and reduced fade during aggressive driving. The steel-backed lining enhances burst strength and durability, while the chrome-moly hub is heat-treated for increased strength and longevity. Carefully selected rivet materials and design maximize strength and reliability, making this clutch suitable for demanding street and race environments. The lightweight design of these discs facilitates faster shifts and improved response, essential for performance driving. ACT's clutch components are 100% clamp load tested and dynamically balanced to ensure smooth operation at high RPMs, delivering consistent performance and extended service life. The kit offers a balanced combination of race-proven performance and street manageability, making it an ideal upgrade for enthusiasts seeking durability and performance. Backed by ACT's industry-leading one-year warranty, the BM14-HDSD clutch kit provides confidence and peace of mind for your vehicle's drivetrain enhancements.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eHeavy-duty pressure plate with increased clamp load and reduced deflection\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eExclusive diaphragm design for enhanced clamping and longevity\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFour-stage heat-treated diaphragm for reliable high-performance engagement\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePrecision cover stampings increase rigidity and consistency\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eStreet rigid-hub clutch disc with high copper organic friction materials for heat transfer\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSteel-backed lining for greater burst strength and durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eChrome-moly hub heat-treated for increased strength\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLightweight disc design for faster shifts and improved response\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e100% clamp load tested and dynamically balanced for smooth high RPM operation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIdeal for street and race applications, backed by a one-year warranty\u003c\/li\u003e\u003c\/ul\u003e\n\n\u003cp\u003eFitment:\n\u003cbr\u003e2007 BMW 335i Base\n\u003cbr\u003e2007 BMW 335xi Base\n\u003cbr\u003e2008 BMW 135i Base\n\u003cbr\u003e2008 BMW 335i Base\n\u003cbr\u003e2008 BMW 335xi Base\n\u003cbr\u003e2008 BMW 535i Base\n\u003cbr\u003e2008 BMW 535xi Base\n\u003cbr\u003e2009 BMW 135i Base\n\u003cbr\u003e2009 BMW 335i Base\n\u003cbr\u003e2009 BMW 335i xDrive Base\n\u003cbr\u003e2009 BMW 535i Base\n\u003cbr\u003e2009 BMW 535i xDrive Base\n\u003cbr\u003e2009 BMW Z4 sDrive35i\n\u003cbr\u003e2010 BMW 135i Base\n\u003cbr\u003e2010 BMW 335i Base\n\u003cbr\u003e2010 BMW 335i xDrive Base\n\u003cbr\u003e2010 BMW 535i Base\n\u003cbr\u003e2010 BMW 535i xDrive Base\n\u003cbr\u003e2010 BMW Z4 sDrive35i\n\u003cbr\u003e2011 BMW 135i Base\n\u003cbr\u003e2011 BMW 335i Base\n\u003cbr\u003e2011 BMW 335i xDrive Base\n\u003cbr\u003e2011 BMW 335is Base\n\u003cbr\u003e2011 BMW 535i Base\n\u003cbr\u003e2011 BMW Z4 sDrive35i\n\u003cbr\u003e2012 BMW 135i Base\n\u003cbr\u003e2012 BMW 335i Base\n\u003cbr\u003e2012 BMW 335i xDrive Base\n\u003cbr\u003e2012 BMW 335is Base\n\u003cbr\u003e2012 BMW 535i Base\n\u003cbr\u003e2012 BMW Z4 sDrive35i\n\u003cbr\u003e2013 BMW 135i Base\n\u003cbr\u003e2013 BMW 335i Base\n\u003cbr\u003e2013 BMW 335i xDrive Base\n\u003cbr\u003e2013 BMW 335is Base\n\u003cbr\u003e2013 BMW 535i Base\n\u003cbr\u003e2013 BMW Z4 sDrive35i\n\u003cbr\u003e2014 BMW 335i Base\n\u003cbr\u003e2014 BMW 335i xDrive Base\n\u003cbr\u003e2014 BMW 435i Base\n\u003cbr\u003e2014 BMW 435i xDrive Base\n\u003cbr\u003e2014 BMW 535i Base\n\u003cbr\u003e2014 BMW Z4 sDrive35i\n\u003cbr\u003e2015 BMW 335i Base\n\u003cbr\u003e2015 BMW 335i xDrive Base\n\u003cbr\u003e2015 BMW 435i Base\n\u003cbr\u003e2015 BMW 435i xDrive Base\n\u003cbr\u003e2015 BMW Z4 sDrive35i\n\u003cbr\u003e2016 BMW 435i Base\n\u003cbr\u003e2016 BMW 435i xDrive Base\n\u003cbr\u003e2016 BMW Z4 sDrive35i\u003c\/p\u003e","brand":"ACT","offers":[{"title":"Default Title","offer_id":45981144350919,"sku":"actBM14-HDSD","price":887.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0665\/2277\/5751\/files\/f4867c5d332f27cda178d3cfaec5acf1.jpg?v=1766514006","url":"https:\/\/mainstreeteshop.com\/products\/act-heavy-duty-street-rigid-clutch-kit-for-bmw-135i-335i-535i-and-z4-part-number-actbm14-hdsd","provider":"MAIN STREET ESHOP","version":"1.0","type":"link"}
