If you're serious about performance, you know that the right engine bearings can make all the difference. That’s where the ACL Race Series Engine Bearings come into play. These aren’t just any bearings; they’re designed for those high RPM conditions that make your heart race and your engine roar. Whether you’re working with a 4, 6, or 8-cylinder setup, these bearings are crafted to handle the heat and stress of serious driving.

Let’s talk about what makes these bearings stand out. First off, the high strength overlay plate is thinner, which means better fatigue resistance. This is crucial when you’re pushing your engine to the limit. Plus, the hardened steel backs on all the rod bearings provide solid support for the lining, ensuring they stay put even when the pressure’s on.

One of the key features is the increased crush that enhances bearing retention. You don't want your bearings moving around when you're hitting those high speeds. And forget about flash plating on the back; that’s been eliminated to improve heat transfer. This means your bearings can handle the heat better and maintain a solid grip in their housing.

Another cool aspect is the increased eccentricity. This helps compensate for any bore distortion at high RPMs, which is essential for forming those hydrodynamic oil films that keep everything running smoothly. And with the 3/4 grooved main bearings, you get optimized load carrying surface area and improved oil flow to the conrod bearings. It’s all about keeping that engine lubricated and happy.

Speaking of precision, the wall tolerances are tight and consistent, which helps you maintain reliable clearances. And if you’ve got performance crankshafts with large fillet radii, the enlarged ID chamfers on the bearing edges are a nice touch that accommodates that extra size without a hitch.

Now, for the specs: you can choose from STD, .025, or .25 sizes, and they come in upper and lower half types. The materials used are tri-metal with hardened steel backs, designed to withstand the rigors of performance driving. They fit various models, including the Dodge Challenger (2008-2020) and Dodge Magnum (2005-2008). These bearings are ideal for the Chrysler 345 5.7L Hemi V8 with a .25 oversized high-performance con rod bearing set.

So, if you’re looking to give your engine the best chance at peak performance, these ACL Race Series Engine Bearings are worth considering. They’re built for the real-world demands of high-performance driving and can help take your ride to the next level.
