Product Details

The King Engine Bearings MB5280SI0.5 is a precision-engineered main bearing set designed specifically for Ford 281 cubic inch (4.6L) engines. This complete set provides the critical interface between the crankshaft and engine block, ensuring proper oil clearance and reliable engine operation.

Key Features:

  • 0.5mm (0.020") oversize for worn crankshaft journals
  • High-performance tri-metal construction with steel backing
  • Proprietary pMax Black coating reduces friction and wear
  • Engineered oil grooves optimize lubrication distribution
  • Precise tolerances for proper clearance specifications
  • Complete main bearing set for all journal positions

King Engine Bearings are manufactured to OEM specifications or better, making them ideal for engine rebuilds, performance applications, and high-mileage restoration projects. The oversize dimension compensates for crankshaft journal machining, restoring proper clearances in engines with worn components.

Application: Ford 4.6L (281 cubic inch) V8 engines with 0.5mm undersize crankshaft journals.
