If you’re serious about pushing your engine to its limits, you’ll want to take a closer look at these ACL Race Series Engine Bearings. These aren’t your run-of-the-mill bearings; they’re crafted with a unique blend of design, metallurgy, and engineering know-how that really delivers when it comes to high-performance applications. Whether you’re revving up a 4, 6, or 8-cylinder engine, these bearings are built to handle the heat—literally.

Let’s break down what makes these bearings stand out:

• High Strength Overlay: They’ve got a thinner overlay plate that actually improves fatigue properties. This means they can take a beating without breaking down.
• Hardened Steel Backs: All the rod bearings come with hardened steel backs. This not only supports the bearing lining but also helps keep everything snug in the housing.
• Increased Crush: The design has a bit more crush to it, which really helps with bearing retention. You don’t want your bearings moving around when you’re pushing hard!
• No Flash Plating: They’ve ditched the flash plating on the backs, allowing for better heat transfer. This means your bearings stay cooler and grip better in their housing.
• Increased Eccentricity: This feature compensates for any bore distortion when you’re hitting those high RPMs, helping to form hydrodynamic oil films that keep everything running smoothly.
• 3/4 Grooved Main Bearings: These are designed to optimize the load-carrying surface area and ensure oil flows freely to the conrod bearings. Better oil flow means better performance.
• Tight Wall Tolerances: You’ll appreciate the consistent wall tolerances that help maintain clearances. It’s all about precision.
• Enlarged ID Chamfers: Where necessary, you’ll find enlarged ID chamfers on the bearing edges to fit larger fillet radii on performance crankshafts.
