These King SI-Series main bearings are recommended for OE applications. These main bearings are designed for aftermarket gasoline or diesel engine rebuilding and performance engines with OE crankshafts. These King SI-Series main bearings have an improved crankshaft finish for reducing microscopic ferrite peaks on improperly ground or polished nodular cast iron crankshafts. These 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.

Some parts are not legal for sale or use in California on any pollution-controlled motor vehicles
