If you’re diving into some serious performance upgrades for your Ford, you’re going to want to check out these ACL Race Series Engine Bearings. These aren’t just any bearings; they’re designed for those who push their engines to the limit. With a solid mix of smart engineering and quality materials, these bearings are built to handle those high RPMs without breaking a sweat.

What Makes These Bearings Stand Out?

• Strength Where It Counts: The overlay plate is high strength but thinner, which means better fatigue properties. It’s all about keeping your engine running smoothly, even when you’re pushing it hard.
• Solid Support: Each rod bearing has a hardened steel back. This adds extra support for the bearing lining and helps keep it snug in the housing—no one wants their bearings shifting around when they’re hitting the gas.
• Better Retention: With increased crush, these bearings stay put. You’ll notice the difference when you’re revving up; they’re designed to hold their ground.
• Heat Management: Forget about flash plating on the back. This design helps heat transfer better, which is crucial when you’re running your engine hard. It maximizes the grip between the bearings and their housing, keeping everything in check.
• RPM Ready: Increased eccentricity compensates for any bore distortion at high RPM. This helps form those all-important hydrodynamic oil films, keeping things lubricated and running smoothly.
• Optimized Oil Flow: The 3/4 grooved main bearings are designed to maximize the load-carrying surface area and ensure oil flows perfectly to the conrod bearings. No one wants a dry start!
• Consistent Tolerances: Tight wall tolerances mean you can maintain consistent clearances, which is key for performance engines.
• Room for Performance: Enlarged ID chamfers on the edges accommodate larger fillet radii on performance crankshafts, so you can push your setup even further.
