King Engine Bearings MB 540AM0.5 AM-Series Main Bearing Set +0.50mm Oversize

The King Engine Bearings MB 540AM0.5 is an OE-replacement crankshaft main bearing set designed for Isuzu G130, G161, and G200 engines. This set is ground to a +0.50mm oversize specification, making it the correct choice for engines with reground or worn crankshaft journals that require an undersized bearing to restore proper oil clearance.

This set belongs to King's AM Series, which utilizes a standard aluminum-based bi-metal construction equivalent to SAE-783. This material is the softest bi-metal in King's lineup, offering excellent embeddability and conformability, making it well-suited for passenger car engines operating under low to medium loads.

Key Features:

• AM Series bi-metal construction — aluminum-based material (SAE-783 equivalent) for superior embeddability and conformability
• +0.50mm oversize — engineered for use with reground crankshafts requiring journal restoration
• Lead-free formulation — environmentally responsible and user-safe bearing material
• 5 pairs per set — complete main bearing set for full engine rebuilds
• Bull's Eye Tolerance™ Technology — precision manufacturing using computerized wall thickness monitoring for tight tolerances
• OE replacement spec — drop-in fit for factory crankshafts during engine rebuilds
