CRANKSHAFT - Honda H22A4, 100mm Stroke, 4340 Billet) - 55mm Main (97-01)

BC crankshafts are made from the finest, aerospace grade 4340 steel billet material. 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.

Turn your big block Honda into a 2.49L monster with a BC stroker kit. Big gains in horsepower and torque without sacrificing high rpm potential. Custom CP pistons are made to order so this kit is designed for turbo, supercharger and or nitrous (9:1) as well as all motor (14:1+)...you choose the compression ratio and bore size to suit your specific requirements. Highest quality at an affordable price. Maximum recommended bore size is 89mm.
