Description

The King Engine Bearings MB4524SI0.5 is a set of crankshaft main bearings designed for medium load engines or engines with nodular cast iron crankshafts. These bearings are part of King's SI-Series, featuring an aluminum-based material strengthened by 2.5-3% silicon.

They offer improved crankshaft finish to reduce wear on nodular cast iron crankshafts and feature optimized oil clearance for extended engine life, reduced noise, and controlled oil flow. This set is precisely engineered with a 0.50mm undersize to ensure proper fitment and optimal performance.
