4340 billet with jumbo radius snout. 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. Fully system balanced.

The BC & CryoHeat crankshafts are made from the finest, aerospace grade 4340 steel billet material, as well as an EN40B steel version for the high end, violent 2-step launch Outlaw customer.
Both are CNC machined on state of the art, 5 axis Mazak Integrex 300-IV CNC machines to exacting tolerances (.0001"). Every crankshaft is CryoHeat treated & micropolished and 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.
