Product Details

The King Engine Bearings MB5745SI0.5 is a high-performance main bearing set engineered specifically for Subaru FA20 and FB20 boxer engines. This complete main bearing set features King's proven tri-metal construction with a steel backing, copper-lead intermediate layer, and proprietary polymer overlay for exceptional strength, conformability, and wear resistance.

Key Features:

  • 0.5mm (0.020") oversize for precision machining and engine rebuilds
  • Tri-metal construction with pMax Black™ overlay coating for enhanced durability
  • Engineered for Subaru FA20 (BRZ, FR-S, 86) and FB20 (Impreza, Crosstrek, Forester) engines
  • Precision manufacturing tolerances for optimal oil clearance and crankshaft support
  • High-strength steel backing resists fatigue and deformation under extreme loads
  • Copper-lead layer provides excellent embedability and seizure resistance

King Engine Bearings are manufactured to OEM specifications and beyond, making them ideal for both stock rebuilds and high-performance applications. The oversize dimension allows machinists to restore bearing bores to proper clearances during engine reconditioning.
