Product Details

The King Engine Bearings MB559AM040 is an AM-Series crankshaft main bearing set designed for Ford FE and FT big-block engines, including the 330, 352, 360, 390, 410, and 428 cubic inch displacements. This set is ground to a .040-inch (1.00mm) undersize to fit reground crankshafts requiring this specification.

AM-Series Bi-Metal Construction:

  • Bi-metal aluminum construction equivalent to SAE-783 — King's standard aluminum-based material suited for street and marine engine applications with low to medium loads
  • Full-groove upper bearing design promotes consistent crankshaft oiling across all journals
  • Lead-free material — environmentally responsible and user-safe
  • Superior embeddability helps absorb macro-particles to protect crank journals and prevent overlay tearing
  • Tolerance control to ±.0001 inch for precise fitment and minimal shell-to-shell variation

King Bull's Eye Tolerance™ Technology:

  • Combines precision CNC machining, controlled overplating, and computerized wall thickness monitoring
  • Real-time process adjustment ensures industry-leading thickness consistency from shell to shell

This bearing set is an ideal OE-quality replacement choice for engine rebuilds on classic Ford FE/FT platform engines.
