If you’re serious about your engine’s performance, you’ve probably heard of ACL Race Series Engine Bearings. These aren’t just any bearings; they’re designed with a unique blend of materials and engineering that really stands up to the demands of high RPM driving. Whether you’re racing on the track or just pushing your ride a little harder on the street, these bearings have got your back.

Let’s break down what makes these bearings special:

• High Strength Overlay: The overlay plate is thinner but stronger, which means it handles fatigue like a champ. You won’t have to worry about wear and tear as quickly.
• Hardened Steel Backs: All rod bearings come with hardened steel backs. This adds support to the bearing lining and helps keep everything locked in place.
• Increased Crush: The crush has been ramped up for better retention. That means these bearings stay put, even under pressure.
• Heat Transfer: We’ve ditched flash plating on the backs of the bearings. This helps heat dissipate better, ensuring your bearings stay cool and perform optimally.
• Increased Eccentricity: This feature helps combat bore distortion at high RPMs, allowing for better hydrodynamic oil film formation. It’s all about keeping that oil where it needs to be.
• 3/4 Grooved Main Bearings: These are designed to optimize the load-carrying surface area and improve oil flow to the conrod bearings. More oil where it matters most.
• Tight Wall Tolerances: Consistency is key. These bearings help you maintain the clearances you need for peak performance.
• Enlarged ID Chamfers: We’ve made adjustments on the edges to fit larger fillet radii on performance crankshafts, ensuring a snug fit.

Now, let’s talk specs:
