ACL Race Series Engine Bearings - 4B1185A-STD

When it comes to enhancing the performance of your Mitsubishi Eclipse (1990-2011) or Galant (1994-2012), the ACL Race Series Engine Bearings are a game-changer. These high-performance trimetal bearings are engineered to handle the demands of higher RPMs, making them an ideal choice for those who push their vehicles to the limit.

Key Features

  • High-strength overlay plate with reduced thickness for improved fatigue resistance.
  • Hardened steel backs on all rod bearings enhance support for the bearing lining and ensure secure retention in the housing.
  • Increased crush for superior bearing retention during intense driving conditions.
  • Eliminates flash plating on the back to enhance heat transfer and maximize grip between the bearings and their housing.
  • Increased eccentricity compensates for bore distortion at high RPMs, aiding in the formation of hydrodynamic oil films.
  • 3/4 grooved main bearings optimize load-carrying surface area and oil flow to the conrod bearings.
  • Tight, consistent wall tolerances help maintain precise clearances for improved performance.
  • Enlarged ID chamfers on bearing edges accommodate large fillet radii on performance crankshafts.
