CNC machined on state of the art, 5 axis Mazak Integrex 300-IV CNC machines to exacting tolerances (.0001\"). Every crankshaft features large radius journals that add rigidity for high horsepower, high boost, high rpm applications. Gun drilled, CNC ground oil holes feature a smooth surface for extra oiling, tear dropped for added oil scoop, cross drilled for priority main feeding to the rods and micro polished to a mirror finish for optimum bearing lubricity. All cranks are stress relieved, shot peened, magna flux inspected and nitrided (multi step heat treatment) for ultimate performance. Fully profiled counterweights are designed for reduced windage through the crankcase creating less oil resistance for better rpm potential. BC also offers REM finish as a standard feature that not only increases oil shedding, but decreases oil foaming and parasitic losses but this polishing process enhances the ion nitriding, increasing overall tensile strength by 10% over the standard BC crankshafts.\u003c\/span\u003e\u003c\/p\u003e\n\u003ctable style=\"background-color: 1px solid #cccccc; width: 100%;\"\u003e\n\u003ctbody\u003e\n\u003ctr bgcolor=\"#FFFFFF\"\u003e\n\u003ctd align=\"right\"\u003eStroke\u003c\/td\u003e\n\u003ctd\u003e3.875\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"#FFFFFF\"\u003e\n\u003ctd align=\"right\"\u003eRod Journal\u003c\/td\u003e\n\u003ctd\u003e2.000\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"#FFFFFF\"\u003e\n\u003ctd align=\"right\"\u003eMain Journal\u003c\/td\u003e\n\u003ctd\u003e2.650\" (400)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Brian Crower Inc","offers":[{"title":"Default Title","offer_id":48881277173912,"sku":"9IU4Q","price":2562.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0564\/0867\/0360\/files\/FullSizeRender_1f17ed31-bfe6-4aa1-9538-0c5a6317c8f8.jpg?v=1776394676","url":"https:\/\/frsport.com\/products\/b-bc5444-3875-sj-b-chevrolet-sb-chevy-crankshaft-4340-forging-3-875-stroke-1800g-rough-balance","provider":"FR SPORT","version":"1.0","type":"link"}
