## Description

Michigan Motorsports Main Bearings Main Bearings, SI-Series, Standard Size, Bi-metal, Silicon Aluminum, Chevy 4.8 5.3 5.7 6.0 6.2 Gen 3/4 Set of 5 Michigan Motorsports SI-Series main bearings are recommended for stock or performance engines using factory crankshafts. The bearings have an improved crankshaft finish for reducing microscopic ferrite peaks on improperly ground or polished nodular cast iron crankshafts. SI-Series main bearings feature improved oil clearance to reduce wear and increase engine life, which in turn reduces operating noise, vibration, and excess oil flow.
