This precision-manufactured bearing set provides the critical interface between your crankshaft and engine block, ensuring smooth rotation and reliable performance.

Key Features:

  • Direct fit for Ford 351ci (5.8L) and 400ci (6.6L) V8 engines
  • Bi-metal silicon aluminum construction for optimal strength and durability
