BC Brian Crower Connecting Rods for 2JZ Toyota Supra (BC6305HD/BC6309HD/BC6307)
BC offers three high-performance connecting rods: the ProH2K, ProH625+, and MOAR Series. The ProH2K is the same as the ProH625+ rods, but uses the economical ARP2000 bolts rated to 220,000 psi, supporting over 175HP per cylinder for everyday enthusiasts. The ProH625+, made from aerospace-grade 4340 steel, features ARP Custom Age 625+ bolts rated to 280,000 psi, offering unmatched clamping for over 250HP per cylinder, ideal for hardcore racers. The MOAR Series, designed with input from top 2JZ builders, is 50 grams heavier than the ProH, featuring an I-Beam design for better clearance in stroker applications, radiused edges for rigidity, and ARP Custom Age 625+ fasteners for superior clamping.
