BRIAN CROWER BC5249 CRANKSHAFT - EN40 BILLET NISSAN GTR R35

BC crankshafts are made from the finest, aerospace grade EN40 steel billet material the same material used in 7000+ horsepower Top Fuel drag. 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.
