They are CNC machined on advanced 5-axis Mazak Integrex 300-IV machines to exacting tolerances of .0001\". Each crankshaft features large radius journals to enhance rigidity for high horsepower, high boost, and high RPM applications. Gun-drilled and CNC-ground oil holes offer smooth surfaces for improved oiling, with tear-dropped designs for added oil scoop and cross-drilled holes for priority main feeding to the rods. Micro-polished to a mirror finish for optimal bearing lubricity, all crankshafts undergo stress relief, shot peening, magnaflux inspection, and nitriding (a multi-step heat treatment) for superior performance. Fully profiled counterweights reduce windage in the crankcase, lowering oil resistance for better RPM potential.\u003c\/p\u003e\n\u003ca href=\"https:\/\/stmtuned.com\/collections\/bc-brian-crower-products\" style=\"color: #afafaf;\"\u003e\u003cbr\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cspan style=\"font-size: .8em;\"\u003e See more BC Products\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/a\u003e","brand":"BC Brian Crower","offers":[{"title":"94.6mm","offer_id":50560589398358,"sku":"BC-BC5320LW","price":3923.16,"currency_code":"EUR","in_stock":true},{"title":"100mm","offer_id":50560589431126,"sku":"BC-BC5321LW","price":5733.83,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/9531\/8102\/files\/bc-brian-crower-crankshaft-b58-mkv-supra-bc5320lw-bc5321lw.jpg?v=1749194224","url":"https:\/\/www.speed-addicts.com\/en\/products\/bc-brian-crower-crankshaft-b58-mkv-supra-bc5320lw-bc5321lw","provider":"Speed Addicts","version":"1.0","type":"link"}
