If you're diving into the world of high-performance engines, you know that the right 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 a solid blend of smart design, top-notch metallurgy, and engineering finesse, crafted for those who push their engines to the limit.

Built to handle those high RPMs that make your heart race, these Trimetal engine bearings are a game changer for your 4, 6, or 8-cylinder setups. They’ve got a high-strength overlay plate that’s thinner than what you might find on stock bearings, which means they can take a beating without giving up on fatigue resistance. And with hardened steel backs on all the rod bearings, you get extra support that keeps the lining in place and helps maintain a snug fit in the housing.

One of the standout features is the increased crush, which enhances bearing retention. This means less worry about the bearings shifting under pressure. Plus, ACL has done away with flash plating on the backs of these bearings, which really helps with heat transfer. That’s crucial when you're pushing your engine hard and need to keep things cool.

When it comes to handling those high RPMs, the increased eccentricity is a nice touch. It compensates for any bore distortion you might encounter and aids in forming those all-important hydrodynamic oil films. And let’s not overlook the 3/4 grooved main bearings, which optimize the load-carrying surface area and ensure your conrod bearings are getting the oil flow they need.

With tight and consistent wall tolerances, you can maintain those clearances you worked so hard to achieve. And if you’re running a performance crankshaft, the enlarged ID chamfers on the bearing edges are designed to accommodate those larger fillet radii. It’s little details like these that show ACL really understands what performance enthusiasts need.

As for specifications, these bearings come in sizes STD, 001, and 010, with standard oil clearance. They’re available in both upper and lower half types, made from tri-metal with hardened steel backs. You’ll find they fit a range of Dodge Chargers from 2006 to 2020, specifically the V8 318/340/360 models with a .30mm oversized trimetal rod bearing set. The minimum standard shaft size is 2.124 inches, while the max is 2.125 inches, ensuring a snug fit in your engine.

So, if you’re serious about performance and reliability, these ACL Race Series Engine Bearings are worth considering. They’re built to last and designed to keep your engine running smoothly under pressure. Trust me, you’ll feel the difference on the track or the street.
