When it comes to pushing your engine to the limit, you want bearings that can keep up with the demands of high performance. 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 cutting-edge metallurgy and engineering that really shines when the RPMs start climbing. Whether you're working on a 4, 6, or 8-cylinder engine, these bearings have got you covered.

One of the standout features is the high-strength overlay plate. It’s thinner than what you might find on standard bearings, which actually helps with fatigue resistance. This means they can take on more stress without giving up. Plus, the hardened steel backs on all rod bearings really enhance support for the bearing lining. This isn’t just about keeping things in place; it’s about ensuring everything runs smoothly, even under pressure.

Another thing I appreciate is the increased crush, which really helps with bearing retention. You don’t want your bearings shifting around when you’re pushing your ride hard. And forget about flash plating on the backs—these bearings are designed for better heat transfer, maximizing grip between the bearings and their housing. This is crucial when you’re running at high RPMs.

Speaking of high RPMs, the increased eccentricity is a game-changer. It compensates for any bore distortion, which is super helpful for forming those hydrodynamic oil films that keep everything lubricated. And let’s not forget the 3/4 grooved main bearings. They optimize the load-carrying surface area and ensure that oil flows smoothly to the conrod bearings, which is essential for high-performance applications.

Now, onto the nitty-gritty specs: these bearings come in sizes STD, 001, and 010, with standard oil clearance. They’re half-type, meaning you’ll get both upper and lower options. Made from tri-metal with hardened steel backs, they’re built to last. If you're curious about dimensions, the minimum standard shaft size is 2.2983 inches, and the maximum is 2.2993 inches. For tunnel sizes, you’re looking at a minimum of 2.4906 inches and a maximum of 2.4916 inches. The wall thickness at the crown maxes out at 0.0954 inches, and the overall length is 0.8067 inches.

These bearings fit a range of vehicles, including the Chevrolet Caprice from 1975 to 1996 and 2000 to 2017, as well as the Chevrolet Corvette from 1975 to 1982 and 1984 to 2013. If you’re working on a classic Chevy, these bearings are definitely worth considering for your build.

In short, if you're serious about performance and want bearings that can handle the heat, the ACL Race Series Engine Bearings might just be what you need. They’re tough, reliable, and designed for the kind of driving that makes your heart race.
