Product Details

The King Engine Bearings MB5505SI main bearing set is engineered for Ford V8 engines with 351 cubic inch (5.8L) and 400 cubic inch (6.6L) 16-valve configurations. These precision-manufactured bearings provide reliable protection for your engine's crankshaft and ensure optimal performance under demanding conditions.

Key Features:

  • Bi-metal silicon aluminum construction for superior durability
  • Aluminum-based material strengthened with 2.5-3% silicon content
  • Designed for medium-load engines and nodular cast iron crankshafts
  • Precision-engineered to meet OEM specifications
  • Direct replacement for Ford 351ci and 400ci V8 applications

King Engine Bearings are manufactured using advanced metallurgy and strict quality control standards. The silicon aluminum alloy provides excellent wear resistance, thermal stability, and load-carrying capacity, making this bearing set ideal for stock rebuilds and performance applications alike. The bi-metal design combines the strength of a steel backing with the superior bearing properties of silicon-enhanced aluminum.
