ACL 5M8412A-.25 Main Bearing Set

The ACL 5M8412A-.25 is a high-quality main bearing set designed specifically for those who demand reliability and performance from their engine components. This set is part of ACL's renowned Race Series, which is known for its robust design and engineering tailored for high RPM applications. Whether you're a casual driver or a serious enthusiast, these bearings are built to withstand the rigors of performance driving.

Features:

  • High strength overlay plate with a reduced thickness that enhances fatigue properties, making it ideal for high-stress conditions.
  • Hardened steel backs on all rod bearings improve support for the bearing lining and aid in retention within the housing.
  • Increased crush for better bearing retention, ensuring that your bearings stay in place under pressure.
  • Flash plating has been eliminated from the back of the bearings to enhance heat transfer and grip between the bearings and their housing.
  • Increased eccentricity helps to compensate for bore distortion at high RPM, supporting the formation of hydrodynamic oil films.
  • 3/4 grooved main bearings optimize the load-carrying surface area and oil flow to the conrod bearings, enhancing overall engine performance.
  • Tight, consistent wall tolerances help maintain clearances, which is crucial for engine longevity.
  • Enlarged ID chamfers on bearing edges accommodate large fillet radii on performance crankshafts.
