King SI-Series rod bearings are recommended for OE applications. These replacement bearings are designed for aftermarket gasoline or diesel engine rebuilding—and performance engines with factory crankshafts. The bearings have an improved crankshaft finish for reducing microscopic ferrite peaks on improperly ground or polished nodular cast iron crankshafts. King SI-Series rod bearings feature improved oil clearance to reduce wear and increase engine life, which in turn reduces operating noise, vibration, and excess oil flow.
Features:
- Softest bi-metal material avaiable.
- Contains Bi-metal, silicon and aluminum.
- Reduces microscopic ferrite peaks.
Specifications:
