ACL 4B8320-.50 Engine Rod Bearing Set

The ACL 4B8320-.50 is a premium rod bearing set designed specifically for high-performance applications, particularly in the 96+ Subaru 2.5L EJ22/EJ25 engines. With its robust construction and thoughtful engineering, this set aims to deliver reliability and durability under demanding conditions.

Features:

  • High strength overlay plate that enhances fatigue resistance, ensuring longevity even at elevated RPMs.
  • Hardened steel backs on all rod bearings provide superior support for the bearing lining and enhance retention within the housing.
  • Increased crush for better bearing retention, helping to keep everything securely in place during operation.
  • Removal of flash plating on the back of the bearings promotes improved heat transfer, maximizing the grip between the bearings and their housing.
  • Enhanced eccentricity helps compensate for bore distortion at high RPMs while facilitating the formation of hydrodynamic oil films.
  • 3/4 grooved main bearings optimize the load-carrying surface area and oil flow to the connecting rod bearings.
  • Tight and consistent wall tolerances help maintain uniform clearances, which is crucial for performance.
  • Enlarged ID chamfers on bearing edges accommodate large fillet radii on performance crankshafts, enhancing compatibility.
