About BC Crankshafts:
BC crankshafts are crafted from aerospace-grade 4340 steel billet, machined on advanced 5-axis Mazak Integrex 300-IV CNC machines to precise tolerances of .0001". Featuring large radius journals for added rigidity, they are gun-drilled and CNC ground for smooth oiling, tear-dropped for enhanced oil scoop, and cross-drilled for priority main feeding to the rods, with micro-polished finishes for optimum bearing lubricity. Stress-relieved, shot-peened, magnaflux inspected, and nitrided for ultimate performance, they boast fully profiled counterweights for reduced windage, minimizing oil resistance for improved RPM potential.

About BC Connecting Rods:
BC connecting rods, machined from aerospace-grade 4340 steel billet, offer a choice between European H-beam or traditional I-beam designs. Featuring a deep, double ribbed cap for consistent big end housing bore, they ensure uniform bearing crush, delivering superior oil supply and load carrying capacity. H-beam rods feature radial groove pin bushing and oil holes for critical wrist pin lubrication, while I-beam rods have oil holes at 12 o'clock for maintaining pin end bore integrity under high boost. Available with ARP2000 fasteners or ARP's Custom Age 625+ fasteners, they offer exceptional strength ratings.

Piston Options:
For pistons, select from top brands like CP or JE in desired bore size and compression ratio. These custom BC stroker pistons are forged from 2618 T6 high tensile strength aluminum, with computer-designed forgings for strength and weight reduction. CNC machined for accuracy and superior grain flow, they undergo rigorous Finite Element Analysis for optimal strength-to-weight ratio. Tighter clearances, reduced noise, improved ring seal, and durability are standard, with options for upgraded wrist pins, lateral gas ports, coatings, and lightweight designs.
