If you're serious about performance, you know that your engine bearings can make or break your ride. That's where the ACL Race Series Engine Bearings come into play. These aren't just any bearings; they’re designed with a unique blend of engineering, metallurgy, and practical know-how to handle those high RPM situations that get your heart racing.

What I love about these bearings is their high-strength overlay plate, which is thinner than what you might find in standard bearings. This reduction in thickness actually helps with fatigue properties, meaning they can take a beating without letting you down. Plus, the hardened steel backs on all the rod bearings give you that added support for the lining, ensuring they stay put in the housing even when the engine's running hot.

One of the standout features is the increased crush, which really enhances bearing retention. You won’t have to worry about them slipping out of place. And forget about flash plating on the back—this design choice helps improve heat transfer and maximizes the grip between the bearings and their housing. Trust me, when you're pushing your engine to the limit, every bit of heat management counts.

These bearings also come with increased eccentricity, which compensates for bore distortion at high RPMs. This is key for forming those hydrodynamic oil films that keep everything lubricated and running smoothly. The 3/4 grooved main bearings are another smart touch; they optimize the load-carrying surface area and ensure oil flows efficiently to the conrod bearings.

Now, let’s talk specs. You’re looking at a standard size with an extra oil clearance of +0.001". They’re made from a solid mix of aluminum, tin, and silicon, which gives you that perfect balance of strength and weight. The tolerances are tight and consistent, so you can maintain your clearances without a hitch. And if you’ve got a performance crankshaft, the enlarged ID chamfers on the edges will accommodate those larger fillet radii without any issues.

These bearings fit a range of popular vehicles, including the Chrysler 300C from 2005 to 2018, the Dodge Charger from 2006 to 2021, and the Dodge Magnum from 2005 to 2008. Specifically, the 8B1808HX-STD set is designed for Chrysler's 345 and 370ci (5.7/6.1L) Hemi engines, ensuring you get the high-performance edge you need.

In short, if you want to push your engine to its limits while keeping everything running smoothly, these ACL Race Series Engine Bearings are a solid choice. They’re built for those who demand performance without compromise.
