Engine Connecting Rod Bearing Set Polymer Coated BMW N51 N52 N54 N55 3.0L

These high-performance connecting rod bearings are enhanced with IROX® polymer coating, specifically designed for the demanding environment of BMW N-series engines. In high-boost turbocharged applications like the N54 and N55, the rod bearings face extreme reciprocating loads; the polymer coating provides superior fatigue resistance and improved emergency running properties. This technology is particularly beneficial for vehicles with Start/Stop systems, as it prevents metal-to-metal contact during the critical moments before full oil pressure is reached. By reducing friction and increasing the load-carrying capacity of the bearing shell, these IROX® coated bearings ensure long-term durability and protection for your crankshaft’s rod journals under both daily driving and performance conditions.
