King SI-Series Rod Bearings

4.57 out of 5 stars 92 Customer Reviews

King SI-Series rod bearings are recommended for OE applications. They're designed for aftermarket gasoline or diesel engine rebuilding and performance engines with OE crankshafts. These direct replacements have an improved finish for reducing microscopic ferrite peaks on improperly ground or polished nodular cast iron crankshafts. King SI-Series rod bearings also feature improved oil clearance to reduce wear and increase engine life—which, in turn, lessens operating noise, vibration, and excess oil flow. Hundreds of sets are available; order the bearings recommended for your vehicle.
