Alright, let’s talk about these ACL Race Series Engine Bearings. If you’re pushing your engine to the limits, you need bearings that can keep up. These bad boys are crafted from a unique blend of design, metallurgy, and engineering that really hits the sweet spot for high-performance applications. They’re built to handle those high RPMs without flinching, making them a solid choice for popular 4, 6, and 8-cylinder setups.

Features You’ll Appreciate:

• Strong Overlay: The high-strength overlay plate is thinner, which means it’s got improved fatigue properties. Less weight, more strength.
• Hardened Steel Backs: All the rod bearings come with hardened steel backs. This adds extra support to the bearing lining and helps keep everything snug in the housing.
• Better Retention: They’ve increased the crush for better bearing retention. No one wants to worry about their bearings shifting under pressure.
• Heat Transfer: Flash plating on the back of the bearings? Forget it. These are designed to improve heat transfer, making sure they stay cool even when the engine is hot.
• High RPM Ready: With increased eccentricity, these bearings compensate for bore distortion at high RPMs, which helps in forming hydrodynamic oil films. This means smoother operation when you’re really pushing it.
• Optimized Oil Flow: The 3/4 grooved main bearings maximize the load-carrying surface area and ensure oil flows smoothly to the conrod bearings. This is crucial for keeping everything lubricated.
• Consistent Tolerances: Tight wall tolerances mean you can maintain consistent clearances, which is key for performance builds.
• Chamfered Edges: Enlarged ID chamfers on the bearing edges accommodate large fillet radii on performance crankshafts. This is a detail that makes a difference when you’re building for power.
