If you're diving into some serious performance work on your Chevy, you might want to check out these ACL Race Series Engine Bearings. They’re not your average bearings; they’re designed for the kind of high RPM action that gets your heart racing and your engine singing. These bad boys are made from a unique blend of materials and engineering know-how, so you can trust they’ll handle the heat—literally.

What Makes These Bearings Stand Out?

• High Strength Overlay: The overlay plate is thinner but tough, which means it can handle fatigue better. It’s all about keeping your engine running smoothly.
• Hardened Steel Backs: All rod bearings come with hardened steel backs. This not only supports the bearing lining but also helps keep everything snug in the housing.
• Improved Bearing Retention: With increased crush, these bearings stay put, even when things get wild under the hood.
• No Flash Plating: Say goodbye to flash plating on the back. This change helps with heat transfer and ensures a solid grip between the bearing and housing.
• Increased Eccentricity: This feature compensates for any bore distortion at high RPMs, helping to form those all-important hydrodynamic oil films.
• 3/4 Grooved Main Bearings: They optimize the load-carrying surface area and ensure oil flows smoothly to the conrod bearings.
• Tight Wall Tolerances: Consistent wall tolerances mean you can maintain those critical clearances without a hitch.
• Enlarged ID Chamfers: These are designed to fit performance crankshafts with larger fillet radii, making installation a breeze.
