MIA's Description

The King Engine Bearings MB 557SI 010 is a set of SI-Series main bearings designed for OE applications and aftermarket engine rebuilding. These bearings are made from a bi-metal, silicon aluminum material and feature an improved crankshaft finish to reduce peaks on nodular cast iron crankshafts.

These main bearings are suitable for performance engines with factory crankshafts and offer improved oil clearance. This design helps to reduce wear, increase engine life, and minimize operating noise, vibration, and excess oil flow. The set includes 5 bearings and is designed for a 0.010 in. crankshaft undersize. It features a 1/2 groove style and upper groove location, with a maximum thrust bearing oversize.
