Brian Crower ProH625K HD Connecting Rods for BMW B58B30B - 5.830in w/ ARP625+ Fasteners (BC6321HD)
$1,471.05
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Engineered for high-horsepower BMW B58B30B builds, these Brian Crower ProH625K HD connecting rods are designed to handle the extreme cylinder pressures of high-boost forced induction and competitive racing. The ProH625K series features a heavy-duty H-beam profile manufactured from premium 4340 steel alloy, providing superior fatigue life and dimensional stability compared to factory components.
This ProH625K HD kit is specifically equipped with ARP625+ Custom Age fasteners. These ultra-high-strength bolts provide the necessary clamping force to maintain rod bearing integrity and prevent cap walk under extreme RPM and torque loads. Whether you are building a street-performance engine or a dedicated track car, these rods offer the structural security required for the B58 platform.
