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