BC625+ Material for the Most Demanding Builds

Brian Crower's BC625+ connecting rods use a premium alloy specifically chosen for extreme high-horsepower applications, where a standard forged rod material starts to become the limiting factor rather than the rest of the build. At 5.141 inches in length, this rod is dimensioned specifically for the EJ205/EJ257 platform, not a generic length adapted to fit. For a genuinely serious, high-boost or high-RPM build, rod material and fastener quality stop being optional details and become the difference between reliability and failure. That's exactly the kind of thoughtful design worth paying for.

ARP Custom Age 625+ Fasteners, Not an Afterthought

This rod includes ARP Custom Age 625+ fasteners, a premium bolt material matched to the rod's own high-strength construction rather than a generic bolt that happens to fit the thread pattern. That fastener-to-rod material matching matters enormously at the clamping loads a serious connecting rod bolt experiences under hard use. It's sold individually, so make sure you're ordering the full quantity needed for your engine's cylinder count. For a component this critical, that level of engineering is worth having.
