King Engine Bearings Main Bearing Set Oversize Bi-Metal

King Engine Bearings oversize bi-metal main bearing sets are crankshaft main bearings for engine rebuilds. They suit engines with reground or machined crankshafts that need a bearing with extra thickness to restore proper oil clearance. Their aluminum-silicon bearing surface bonded to a steel back suits OE-replacement rebuilds and many street performance builds.

Key Features:

• Bi-metal construction: a strong aluminum-silicon alloy lining on a steel backing.
• Lead-free material: aluminum-based, with no lead in the bearing surface.
• Silicon-strengthened alloy: helps condition journal surfaces and resists wear and seizure. It suits medium-load engines and engines with nodular cast iron crankshafts.
• Oversize options: designed to restore correct bearing clearances on crankshafts that have been reground.
• OE-replacement quality: built to a precise standard for reliable fit and long service life.

King Engine Bearings was founded in 1960. It supplies bearings for automotive, light- and heavy-duty truck, marine, aviation and standby-power engines. Choose the part number that matches your engine and crankshaft journal size.
