If you're diving into the world of performance engines, you know that good bearings are where it all starts. The ACL Race Series Engine Bearings are crafted for those who push their engines to the limit, whether you're revving up a 4, 6, or 8-cylinder beast. These aren't your run-of-the-mill bearings; they’re built to handle the heat and stress of high RPMs without breaking a sweat.

What makes these bearings stand out?

• First off, they've got a high-strength overlay plate that's thinner than usual. This isn’t just for show; it improves fatigue resistance, meaning they can take a beating and keep on going.
• All the rod bearings come with hardened steel backs. This means better support for the lining and helps keep everything locked in place, so you don’t have to worry about any slip-ups.
• They also feature increased crush for better retention. This is crucial, especially when you’re pushing your engine hard.
• Forget about flash plating on the back—these bearings are designed to optimize heat transfer. This helps keep things cooler and ensures a solid grip between the bearings and the housing.
• With increased eccentricity, they compensate for bore distortion at high RPMs, which is key for forming those hydrodynamic oil films that keep everything lubricated.
• The 3/4 grooved main bearings are a nice touch, maximizing the load-carrying surface area and ensuring oil flows smoothly to the conrod bearings.
• Consistent wall tolerances mean you can maintain precise clearances, which is crucial for performance builds.
• Plus, you'll find enlarged ID chamfers on the edges where it's needed, making them compatible with performance crankshafts that have larger fillet radii.
