Description

The King Engine Bearings MB5227AM is a set of main bearings designed for OE replacement and performance engine rebuilding. These SI-Series bearings feature improved oil clearance to reduce wear and increase engine life. They also help reduce operating noise, vibration, and excess oil flow.
