If you're diving into the nitty-gritty of engine performance, you might want to take a closer look at these ACL Race Series Engine Bearings. These aren't just any bearings; they’re crafted for those of us who push our engines to the limit—think higher RPMs and the kind of stress that can make or break your ride. Whether you’re working on a 4, 6, or 8-cylinder setup, these bearings are designed to handle the heat and keep your engine running smoothly.

What Makes These Bearings Stand Out?

  • High Strength Overlay: The overlay plate is thinner but packs a punch with improved fatigue resistance. This means they can take a beating without giving up.
  • Hardened Steel Backs: All rod bearings come with hardened steel backs. This not only supports the bearing lining but also helps keep everything snug in the housing.
  • Improved Bearing Retention: With increased crush, these bearings stay put when the action gets intense.
  • Heat Transfer: Forget about flash plating on the backs; these bearings are designed for better heat transfer, which means they stay cooler and grip better.
  • Eccentricity Boost: Increased eccentricity helps counteract bore distortion at high RPMs and aids in forming those all-important hydrodynamic oil films.
  • Optimized Oil Flow: The 3/4 grooved main bearings maximize load carrying surface area and ensure that oil flows seamlessly to the conrod bearings.
  • Tight Tolerances: Consistent wall tolerances mean you can maintain your clearances without any guesswork.
  • Chamfered Edges: Enlarged ID chamfers accommodate larger fillet radii on performance crankshafts, making installation a breeze.
