ACL 5M2167H-.25 Performance Main Bearing Set

The ACL 5M2167H-.25 is a well-crafted performance main bearing set designed specifically for the Ford/Cosworth 2.0L (YB) engine. This set stands out due to its unique blend of design and metallurgy, making it a reliable choice for high-performance applications.

Features

  • High strength overlay plate with reduced thickness, enhancing fatigue resistance.
  • Hardened steel backs on all rod bearings, which provide better support for the bearing lining and improve retention within the housing.
  • Increased crush for superior bearing retention.
  • Elimination of flash plating on the back of the bearings, promoting better heat transfer and ensuring a strong grip between the bearings and their housing.
  • Enhanced eccentricity to counteract bore distortion at higher RPMs, aiding in the formation of hydrodynamic oil films.
  • 3/4 grooved main bearings to optimize load-carrying surface area and oil flow to the conrod bearings.
  • Tight wall tolerances to help maintain consistent clearances throughout use.
  • Enlarged ID chamfers on bearing edges where necessary to accommodate larger fillet radii found on performance crankshafts.
