Product Details

The King Engine Bearings MB5739XPG-STDX is a precision-engineered main bearing set designed specifically for Subaru EJ-series engines, including the EJ20, EJ22, and EJ25 models. This performance bearing set features a +.002" oversized housing bore dimension, making it ideal for engine blocks that have been line-bored or honed to restore crankshaft main journal alignment and bearing crush specifications.

Key Features:

  • Designed for Subaru EJ20, EJ22, and EJ25 engines
  • +.002" oversized housing bore for line-bored or align-honed blocks
  • XPG coating for enhanced protection and reduced friction
  • High-performance tri-metal construction for durability
  • Precision-manufactured to OE specifications and tolerances
  • Complete main bearing set for full crankshaft installation

King's XPG (eXtra Performance Grade) series bearings feature an advanced polymer coating that provides superior protection during critical start-up conditions and reduces friction throughout the engine's operating range. The tri-metal construction combines a steel backing with a high-strength copper-lead intermediate layer and a specialized overlay material, delivering excellent load-carrying capacity and fatigue resistance. This bearing set is essential for rebuilders working with blocks that have been machined to correct main bearing bore alignment issues or wear.
