The SunCoast A1-BFP-ZB Billet Flex Plate is a serious upgrade that eliminates the common failures seen with stock stamped steel or cast iron flywheels. Whether you're towing heavy, running big tuning, or simply putting your truck to work, this one-piece billet steel plate delivers the strength and durability your build demands. It’s designed to transfer torque more efficiently by providing a solid, flex-free connection between the crankshaft and your upgraded torque converter. You get better power delivery, less driveline shock, and peace of mind knowing your flex plate isn’t the weakest link. This is the kind of upgrade you do once, knowing it's built to take abuse for the long haul. If reliability and performance are at the top of your list, this billet plate belongs in your setup.\u003c\/p\u003e\n\u003ch4\u003eDesigned To Eliminate Flex Plate Failure Under Load\u003c\/h4\u003e\n\u003cp\u003eThe SunCoast A1-BFP-ZB Billet Flex Plate is engineered to directly replace the factory flywheel on 2011–2016 GM 2500HD and 3500HD Duramax LML trucks, offering a major structural upgrade where it matters most. Factory units rely on stamped steel and cast iron materials, which are known to crack or separate when exposed to high torque loads, especially when paired with a performance torque converter. This billet steel flex plate eliminates those weak points with a precision-machined, one-piece design that bolts directly to the crankshaft and torque converter. It’s capable of handling increased engine torque and transmits power with improved consistency and reduced deflection under load. By reinforcing the connection between engine and transmission, this upgrade ensures smoother engagement, reduced risk of failure, and better long-term durability. It’s an ideal choice for tuned trucks, heavy-duty towing, or performance builds running higher stall converters. When power and reliability are non-negotiable, this flex plate is a critical component you can trust.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e2011, 2012, 2013, 2014, 2015, 2016 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax LML\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits 2011–2016 GM 2500HD\/3500HD 6.6L Duramax LML\u003c\/li\u003e\n\u003cli\u003eReplaces factory cast iron and stamped steel flex plate\u003c\/li\u003e\n\u003cli\u003eOne-piece billet steel design improves strength and reliability\u003c\/li\u003e\n\u003cli\u003eDesigned to handle high torque from tuned engines\u003c\/li\u003e\n\u003cli\u003eIdeal for use with performance torque converters\u003c\/li\u003e\n\u003cli\u003ePrevents center cracking or tearing under heavy load\u003c\/li\u003e\n\u003cli\u003eImproves torque transfer to the transmission input shaft\u003c\/li\u003e\n\u003cli\u003eRecommended for high horsepower or towing applications\u003c\/li\u003e\n\u003cli\u003eProvides a more stable and slip-free connection\u003c\/li\u003e\n\u003cli\u003eBolts directly to the crankshaft and torque converter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"SunCoast Performance","offers":[{"title":"Default Title","offer_id":68060757557521,"sku":"SUN-A1-BFP-ZB","price":674.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/0477\/1089\/files\/SUNA1-BFP-ZB_20FLEXPLATE_2000.jpg?v=1794723810","url":"https:\/\/gautoparts.com\/products\/suncoast-a1-bfp-zb-billet-flex-plate-11-16-gm-6-6l-duramax-lml","provider":"Guaranteed Auto Parts","version":"1.0","type":"link"}
