If you're diving into the world of high-performance engines, you know that every detail counts. That’s where the ACL Race Series Engine Bearings come into play. These aren't just your run-of-the-mill bearings; they’re crafted with a unique blend of design, metallurgy, and engineering that really stands up to the demands of higher RPM conditions. Whether you’re working on a classic Ford Mustang or a beefy Falcon, these bearings are made for the job.

What sets these bearings apart? For starters, the high-strength overlay plate is thinner, which means better fatigue resistance. You won’t have to worry about them giving out when you’re pushing your engine to the limits. Plus, every rod bearing is backed with hardened steel to keep everything in place and support the lining effectively. It’s all about that solid grip, especially when you're revving hard.

Another cool feature is the increased crush that enhances bearing retention. You want your bearings to stay put, right? And speaking of staying put, the elimination of flash plating on the backs of these bearings really helps with heat transfer. This means they can handle the heat better and maintain that all-important grip in their housing. Trust me, when you’re in the thick of it, you’ll appreciate that extra edge.

These bearings also come with increased eccentricity, which is a fancy way of saying they’re designed to deal with bore distortion at high RPMs. This feature helps in forming hydrodynamic oil films, making sure everything runs smoothly. And if you’re curious about oil flow, the 3/4 grooved main bearings optimize the load-carrying surface area, ensuring your conrod bearings get the lubrication they need.

Let’s not forget about the tight wall tolerances that help maintain consistent clearances, which is crucial for performance. And if you've got a performance crankshaft, the enlarged ID chamfers on the bearing edges accommodate larger fillet radii, so you can push your engine without worrying about compatibility.

In terms of specifications, these bearings come in various sizes (STD, 001, 009, 010, 011, 020) and standard oil clearance, ensuring a good fit for your needs. They’re made from tri-metal hardened steel backs, which you can trust for durability. The minimum standard shaft size is 2.1228 inches, and they fit a range of classic Ford models, including:

• Ford Fairlane (1955-1970)
• Ford Falcon (1960-1970)
• Ford Mustang (1964-1973 & 1979-2022)
• Ford Mustang GT (2015-2022)
• Ford Mustang II (1974-1978)

So, if you’re looking to upgrade your engine and really want to feel the difference, these ACL Race Series Engine Bearings are a solid choice. They’ve got the specs and the performance to back them up, making them perfect for anyone serious about their ride.
