King rod bearings feature advanced metallurgical and geometric technologies that meet extreme performance loads. They were developed for all performance applications that use forged steel aftermarket crankshafts and produce high loads for extended periods.


King SI-Series Rod Bearings - CR4538CA


King main bearings are recommended for OE applications. These replacement bearings are designed for aftermarket gasoline or diesel engine rebuilding—and performance engines with factory crankshafts. The bearings have an improved crankshaft finish for reducing microscopic ferrite peaks on improperly ground or polished nodular cast iron crankshafts. King SI-Series main bearings feature improved oil clearance to reduce wear and increase engine life, which in turn reduces operating noise, vibration, and excess oil flow.
