MIA's Description

The King Engine Bearings MB5539AM 040 is a set of AM-Series main bearings designed for street or marine applications. These crankshaft bearings are made from an Alecular silicon bi-metal material and feature a full groove design with upper and lower grooves in a 3/4 style. They are designed for a 0.040 inch (1.00mm) undersize crankshaft.

These bearings offer superior embeddability to reduce scratching of crank journals and protect Babbitt overlays. They also feature precise tolerance control, held within plus or minus .0001, and are lead-free for environmental and user safety. This set includes 5 bearings.
