King SI-Series main bearings are replacement bearings designed for performance engines with a factory crankshaft. 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. 

Note: Suits engines with thrust in #5 position
