King Engine Bearings Main Bearing Set Oversize

King Engine Bearings Main Bearing Sets in oversize are crankshaft main bearings made for engine rebuilds. They are used when the crankshaft journals have been machined undersize. The thicker bearing shells restore the correct oil clearance between the crank journal and the block. Each set is made for engine builders and machine shops who want dependable, precise crankshaft support.

Key Features:

• Oversize main bearing design that matches reground crankshaft journals and restores proper bearing clearance
• Precision-manufactured bearing shells for consistent wall thickness and fit
• Made for the high loads and rotational forces on the crankshaft main journals
• Supports healthy oil film and engine oil pressure when it is installed to specification
• Backed by King Engine Bearings, a well-known name in engine bearings for passenger car, performance, diesel, and industrial engines

Measure the crankshaft journals and oil clearances carefully before installation. Use the oversize that matches your machining. Each variant in this product line has its own part number and oversize specification.
