About this part

Product Details

These King Engine Bearings main bearing set features an alecular construction, part of their racing line, which offers improved durability for performance applications. This set is specifically sized at .026 inches oversize, meaning it's intended for crankshafts that have been machined to that dimension. They are designed for Ford 281 4.6L SOHC 16V engines, commonly found in vehicles like the Ford F-150, Mustang, and Lincoln Town Car.

The alecular material is a bi-metal compound chosen for its strength and ability to handle higher loads, making it a solid option when rebuilding or modifying your engine. Because these bearings are oversize, they are meant to be installed on a crankshaft that has been ground to the specific .026 inch undersize. This ensures a proper, snug fit that is crucial for oil pressure and bearing longevity.

When rebuilding your engine, using bearings from a reputable manufacturer like King Engine Bearings is important. This set is a direct replacement for the factory main bearings, but with enhanced materials for those looking for a bit more from their engine build. Always ensure your crankshaft journals are properly machined and cleaned before installing new bearings.
