Let’s talk about the ACL Race Series Engine Bearings. If you’re pushing your engine to the limit, you need something that can keep up. These bearings are crafted with a blend of smart design and solid metallurgy, making them a go-to for anyone who knows their way around a high-performance engine. They’re built to handle those higher RPMs without breaking a sweat.

Here’s what makes these bearings stand out:

  • They feature a high-strength overlay plate that’s thinner than what you’d typically find, which helps with fatigue resistance. Less thickness, more strength—what’s not to love?
  • All rod bearings come with hardened steel backs, giving the lining better support and keeping everything snug in the housing. No one wants their bearings shifting around, right?
  • With increased crush, these bearings hold onto their spot better, ensuring they stay put when you really need them to.
  • They’ve ditched the flash plating on the back, which means better heat transfer. This helps keep your engine cool and maximizes the grip between the bearing and housing.
  • The increased eccentricity is a game changer. It compensates for any bore distortion at high RPMs and helps form those all-important hydrodynamic oil films.
  • 3/4 grooved main bearings? Yes, please! This design optimizes the load-carrying surface area and improves oil flow to the conrod bearings, giving you that extra edge.
  • These bearings come with tight, consistent wall tolerances, which means you can maintain your clearances without any guesswork.
  • And if you’re working with performance crankshafts, you’ll appreciate the enlarged ID chamfers on the bearing edges. They accommodate larger fillet radii, making installation a breeze.
