Description

The King Engine Bearings MB 431SI is a set of crankshaft main bearings. These bearings are constructed from a bimetal-silicon aluminum material.

This SI-Series set is recommended for OE applications and is suitable for aftermarket gasoline or diesel engine rebuilding, as well as performance engines with factory crankshafts. The SI-Series bearings feature improved oil clearance to reduce wear and increase engine life, which can also lead to reduced operating noise and vibration.
