Technical Support & Build Guidance

High horsepower builds demand precision, so set your clearances correctly and follow proper install procedures. Otherwise, failure under boost becomes a real risk.

The BC connecting rods fit Polaris XP Turbo ProH2K engines and use ARP2000 fasteners for strength at high RPM. Each rod uses aerospace-grade 4340 chromoly steel, and manufacturers CNC machine and micro polish every unit for durability. In addition, the rods include aluminum/silicone/bronze pin bushings and tight final honing for proper fit and long-term reliability.
