Product Details

The King Engine Bearings MB5590SI0.5 is a +0.50mm oversized crankshaft main bearing set designed for General Motors L40, LD2, and LF0 2.3L engines. This 10-piece set is engineered to restore precise crankshaft-to-block clearances during engine rebuilds where the main journals have been machined undersized.

Material Construction:

  • Bi-Metal Silicon Aluminum — an aluminum-based bearing material strengthened with 2.5–3% silicon content
  • Designed for medium-load engine applications and engines with nodular cast iron crankshafts
  • Steel backing provides structural rigidity while the aluminum-silicon overlay delivers excellent conformability and embeddability
  • Offers good fatigue strength and corrosion resistance suitable for daily-driven and moderately stressed engines

Product Details:

  • Type: Crankshaft Main Bearing Set
  • Bore Size: +0.50mm Oversized
  • Number of Pieces: 10
  • Interchange Part Numbers: ACL 5M8511P-STD, Clevite MS-1703P, FMOGUL 7054MA
  • UPC: 611500424496
