King Engine Bearings MB 461AM0.5 Main Bearing Set 0.50mm Oversized Subaru Justy

The King Engine Bearings MB 461AM0.5 is a precision-engineered main bearing set designed as a direct replacement for the Subaru Justy (1987–1990). This set is sized at 0.50mm oversized, making it ideal for engine rebuilds where the crankshaft journals have been machined undersize to restore proper clearances.

King Engine Bearings constructs this main bearing set using a bimetal (aluminum-base) design, which delivers an excellent balance of load capacity, conformability, and wear resistance. The aluminum-alloy bearing material provides strong fatigue strength and corrosion resistance suitable for the demands of a rebuilt engine.

Key Features:

• Bimetal (aluminum-base) construction for durability and conformability
• 0.50mm oversized for use with machined crankshaft journals
• Precision-manufactured to tight tolerances for optimal oil film and clearance
