If you're diving into the world of high-performance engines, you know how crucial good bearings are. These ACL Race Series Engine Bearings are a solid choice for anyone looking to push their ride to the limits. Designed specifically for those high RPM conditions, these bearings are built to handle the heat and stress that comes with serious driving. Whether you’re running a 4, 6, or 8-cylinder setup, you’ll find these bearings have you covered.

What Makes Them Stand Out

• High Strength Overlay: The overlay plate is thinner but stronger, giving you better fatigue resistance. This is key for those extended high RPM runs.
• Hardened Steel Backs: All rod bearings feature hardened steel backs. This not only supports the bearing lining but also helps keep everything snug in the housing.
• Increased Crush: This helps with bearing retention, so you won’t have to worry about them moving around when the engine’s screaming.
• Better Heat Transfer: We’ve ditched the flash plating on the back of these bearings. This means heat moves through them better, maximizing grip between the bearings and their housing.
• Increased Eccentricity: This is a fancy way of saying they’re designed to deal with bore distortion at high RPMs, which helps form those all-important hydrodynamic oil films.
• 3/4 Grooved Main Bearings: These optimize oil flow to the conrod bearings and help carry the load effectively.
• Tight Wall Tolerances: Consistent clearances mean you can trust your setup to perform as expected.
• Enlarged ID Chamfers: These are crucial for accommodating larger fillet radii on performance crankshafts, ensuring a proper fit.
