If you're pushing your engine to its limits, you know how crucial it is to have the right bearings in place. That's where these ACL Race Series Engine Bearings come in. They're not just any bearings; they're designed specifically for high-performance applications, which means they can handle the heat and stress of higher RPMs without breaking a sweat. Whether you're working on a 4, 6, or 8-cylinder setup, these bearings are worth a look.

What Makes These Bearings Stand Out?

• Durable Overlay Plate: The high-strength overlay plate is thinner, which actually boosts fatigue resistance. It’s all about keeping things running smoothly, even when you’re really pushing it.
• Hardened Steel Backs: Every rod bearing comes with hardened steel backs. This not only supports the bearing lining but also helps keep everything securely in place in the housing.
• Better Retention: With increased crush, you get improved bearing retention. That means less chance of slippage when you're revving high.
• No Flash Plating: They’ve ditched the flash plating on the back. This helps with heat transfer and maximizes grip between the bearings and the housing—important for those intense runs.
• Increased Eccentricity: This feature helps counteract bore distortion when you're hitting those high RPMs and aids in creating hydrodynamic oil films for better lubrication.
• Optimized Oil Flow: The 3/4 grooved main bearings are designed to maximize the load-carrying surface area and ensure oil flows smoothly to the conrod bearings.
• Consistent Tolerances: Tight wall tolerances mean you can maintain consistent clearances, which is crucial for engine performance.
• Accommodating Design: Enlarged ID chamfers at the edges are included where necessary, making them compatible with performance crankshafts that have larger fillet radii.

These bearings are a perfect fit for the Honda S2000 (2000-2009), specifically for the F20C/F22C engine with a 0.025mm oversized high-performance main bearing set (part number: 5M1913H-.025). If you're serious about getting the most out of your ride, these bearings are a solid choice.
