If you’re diving into the world of performance engines, you’ve probably heard about ACL Race Series Engine Bearings. These aren’t just any bearings; they’re crafted with a combination of smart design, tough metallurgy, and solid engineering to give you what you need when you're pushing your engine to the limits. Whether you’re revving a 4, 6, or 8-cylinder setup, these bearings are built to handle those higher RPMs without breaking a sweat.

What Makes Them Stand Out?

  • High Strength Overlay: The overlay plate is thinner but tougher, which means it can handle fatigue better. This is crucial when you’re pushing your engine hard.
  • Hardened Steel Backs: All rod bearings come with hardened steel backs, giving you better support for the bearing lining and keeping them locked in place where they belong.
  • Improved Crush: With increased crush, these bearings stay put, so you won’t have to worry about them shifting around under pressure.
  • Heat Transfer: They’ve eliminated flash plating on the back, which helps with heat transfer. This means better performance and grip between the bearings and the housing.
  • Increased Eccentricity: This helps counteract bore distortion at high RPMs, which is essential for forming those hydrodynamic oil films that keep everything running smoothly.
  • Optimized Oil Flow: The 3/4 grooved main bearings maximize the load-carrying surface area and ensure that oil flows efficiently to the conrod bearings.
  • Consistent Tolerances: With tight wall tolerances, you can expect consistent clearances, which is a big deal when you’re tuning for performance.
  • Chamfered Edges: The enlarged ID chamfers accommodate those beefy fillet radii on performance crankshafts, making installation a breeze.

These bearings are a reliable upgrade for anyone serious about their build. Trust me, you’ll feel the difference when you hit the gas.
