If you're diving into high-performance builds, you know that engine bearings can make or break your setup. That's where these ACL Race Series Engine Bearings come into play. They’re not just any bearings; they’re crafted from a unique blend of design, metallurgy, and engineering that really delivers when it comes to high RPM performance. I've had my hands on these for a while now, and I can tell you—they hold up like a champ.

What sets these bearings apart? For starters, they feature a high-strength overlay plate that’s thinner than what you might find elsewhere. This isn’t just for show; it significantly improves fatigue properties, which is crucial when you’re pushing your engine to the limit. Plus, every rod bearing comes with hardened steel backs, ensuring that the lining stays supported and doesn’t wiggle around in the housing. Trust me, that’s a big deal when you’re trying to keep everything tight and right.

Another cool feature is the increased crush that enhances bearing retention. No one wants to deal with bearings that slip or shift under pressure. And speaking of pressure, they've eliminated flash plating on the backs of the bearings, which helps with heat transfer. This means better grip between the bearings and the housing—essential for maintaining performance when the heat is on.

When you’re revving high, bore distortion can be a real pain. But these bearings come with increased eccentricity to help counteract that, aiding in the formation of hydrodynamic oil films. And let’s not forget the 3/4 grooved main bearings that optimize load-bearing surfaces and enhance oil flow to the conrod bearings. It's all about keeping that oil where it needs to be.

Now, onto the specs. You’ve got options with sizes like STD, 001, and 010, and they maintain standard oil clearance, so you won’t have to sweat the small stuff. The material? Tri-metal with hardened steel backs—built to last. They fit standard shaft sizes ranging from 2.124 inches to 2.125 inches, and the tunnel sizes are equally precise, sitting between 2.25 inches and 2.2505 inches. This attention to detail means you can count on tight, consistent wall tolerances for maintaining clearances.

These bearings are compatible with a range of vehicles, including the Dodge Viper from 1992 to 2010 and 2015 to 2017, as well as the SRT Viper from 2013 to 2014. If you’re running a Chrysler V8 318-340-360, the 1B481H-.10 ACL Race Series .10 oversized connecting rod bearing set is a solid choice.

In short, if you’re serious about your engine performance, these bearings are worth considering. They’ve got the engineering to back them up, and from my experience, they’ll keep your ride running smooth when it counts.
