ACL 5M1144H-.025 Race Series Engine Bearings

When it comes to high-performance engine builds, the ACL 5M1144H-.025 Race Series Engine Bearings are a game changer for Mitsubishi owners looking to push their engines to the limit. These trimetal bearings are designed specifically for applications with higher RPM demands, making them ideal for both street and track use. Whether you're revving up your 1994-2012 Mitsubishi Galant or your 2002-2017 Mitsubishi Lancer, these bearings are engineered to deliver the reliability and performance that every car enthusiast craves.

Key Features

  • High-strength overlay plate with reduced thickness enhances fatigue resistance, ensuring longevity under stress.
  • Hardened steel backs on all rod bearings provide superior support for the bearing lining and improve retention in the housing.
  • Increased crush enhances bearing retention, keeping everything in place even under extreme conditions.
  • Flash plating has been eliminated from the back of the bearings, which improves heat transfer and maximizes grip between the bearings and housing.
  • Increased eccentricity compensates for bore distortion at high RPM, aiding in the creation of hydrodynamic oil films for better lubrication.
  • 3/4 grooved main bearings optimize load-carrying surface area and enhance oil flow to the conrod bearings.
  • Tight, consistent wall tolerances help maintain precise clearances, crucial for high-performance applications.
  • Enlarged ID chamfers on bearing edges accommodate larger fillet radii found on performance crankshafts.
