If you're diving into the world of high-performance engines, you know that the little things can make a big difference. That's where these ACL Race Series Engine Bearings come in. They're not just your average bearings; they’re designed with some serious engineering know-how to handle the demands of high RPM situations. Whether you're tuning up your Mitsubishi Evolution X or working on a Lancer, these bearings are a solid choice.

  • Strength Where It Counts: The overlay plate is high strength but thinner, which helps reduce fatigue. This means they can take a beating without giving up.
  • Solid Support: The hardened steel backs on all rod bearings provide excellent support for the lining, ensuring they stay put where they belong.
  • Better Retention: With increased crush, these bearings stick better in their housing, so you don’t have to worry about them slipping out when the engine’s revving high.
  • Heat Management: Forget about flash plating on the backs; these bearings improve heat transfer, which is crucial when you're pushing your engine hard.
  • High RPM Ready: Increased eccentricity helps with bore distortion at high RPMs and aids in forming those all-important hydrodynamic oil films.
  • Optimized Flow: The 3/4 grooved main bearings are designed to maximize oil flow to the conrod bearings, keeping everything lubricated just right.
  • Consistent Tolerances: Tight wall tolerances mean you can maintain consistent clearances, which is key for engine performance.
  • Room for Performance: Enlarged ID chamfers on the edges accommodate those larger fillet radii on performance crankshafts, making installation smoother.
