Crankshafts
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.
Connecting Rods
BC connecting rods are CNC machined from aerospace grade 4340 steel billet, available in your choice of the European influenced H beam or the traditional I beam design (certain applications). All rods feature a deep, double ribbed cap that keeps the big end housing bore true at extended rpm and insures uniform bearing crush, delivering proper clearances for superior oil supply and maximum load carrying capacity. H Beam rods feature a deep radial groove pin bushing and oil holes at 5 and 7 o'clock (the beam acts as a trough), bringing critical lubrication to the critical wrist pin area. I Beam rods feature a oil hole at the 12 o'clock position that keep the pin end bore true at high boost. Available in your choice of ARP2000 fasteners (rated to 210,000 psi) or the ultimate faster, ARP's Custom Age 625+ (rated to 280,000 psi).
Pistons
Choose from the top piston brands available... CP or JE... in any desired bore size and compression ratio. Both brands make their custom BC stroker pistons from 2618 T6 high tensile strength forged aluminum forgings. These forgings are computer designed for strength and minimum weight. Each piston dia is CNC machined to assure optimal accuracy and superior grain flow in the forging process. 3D modeling software and rigorous Finite Element Analysis insure that your pistons are manufactured to the strongest and lightest part possible for your application. Your custom pistons feature tighter clearances, less noise, better ring seal and overall better durability. Standard features include pin fit, carbon steel wrist pins and spiral locks or rail supports depending on application. Added features include upgraded 9310 alloy wrist pins for reduced flex, lateral gas ports to assist in ring seal, skirt and top coatings and lightweight design.
