If you're looking to give your engine the kind of love it deserves, these ACL Race Series Engine Bearings are where it’s at. They’re not just another set of bearings; they’re crafted from a unique blend of design and metallurgy that really stands up to the high-performance demands of your ride. Whether you're revving up a 4, 6, or 8-cylinder beast, these bearings are built to handle the heat and high RPMs without breaking a sweat.

• High Strength Overlay: The overlay plate is thinner but tougher, which means better fatigue resistance. That’s key when you’re pushing the limits.
• Hardened Steel Backs: Every rod bearing comes with hardened steel backs. This adds extra support to the bearing lining and helps keep everything snug in the housing.
• Increased Crush: This feature enhances bearing retention, so you can trust that they’re staying put even under stress.
• Better Heat Transfer: We’ve ditched the flash plating on the back of the bearings. This means heat moves through better, maximizing the grip between the bearings and their housing.
• Increased Eccentricity: This little tweak helps counteract bore distortion at high RPMs and aids in forming those all-important hydrodynamic oil films.
• 3/4 Grooved Main Bearings: These are designed to optimize load distribution and oil flow to the conrod bearings, giving you better performance overall.
• Tight Tolerances: Consistent wall tolerances mean you can maintain your clearances without a hitch.
• Enlarged ID Chamfers: We’ve made sure the edges accommodate larger fillet radii on performance crankshafts, so you don’t have to worry about fitment issues.
