If you're looking to push your engine's limits, these ACL Race Series Engine Bearings are where it's at. Built for serious performance, these bearings are designed to handle the high RPMs that come with spirited driving. Whether you’re building a weekend warrior or just want to give your daily driver a boost, these bearings have got you covered.

What makes these bearings stand out?

  • They feature a high-strength overlay plate that's thinner than your typical bearings, which means they can handle fatigue better—perfect for those high-stress situations.
  • All rod bearings come with hardened steel backs that not only support the bearing lining but also help keep everything snug in the housing.
  • With increased crush, these bearings stay put where they belong, ensuring a solid fit.
  • No flash plating on the back means better heat transfer, which is crucial for performance engines that run hot.
  • Increased eccentricity helps with bore distortion at high RPMs, allowing for better oil film formation. That means smoother operation and less wear.
  • The 3/4 grooved main bearings optimize load carrying and oil flow, making sure your conrod bearings get the lubrication they need.
  • Consistent wall tolerances help maintain clearances, so you can keep everything running smoothly.
  • Plus, the enlarged ID chamfers on the edges are designed to fit performance crankshafts with larger fillet radii.
