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 in. These aren’t just any bearings; they’re designed specifically for those of us who push our engines to the limit. Whether you’re working with a 4, 6, or 8-cylinder setup, these bearings are built to handle the higher RPMs that come with serious driving.

What sets these bearings apart? Well, for starters, they feature a high-strength overlay plate that’s thinner than what you’d find in standard options. This reduction in thickness isn’t just for show; it actually enhances fatigue properties, meaning they’re less likely to fail when the going gets tough. Plus, the hardened steel backs on all the rod bearings provide solid support for the bearing lining, ensuring they stay put in the housing even under intense conditions.

One thing I really appreciate is the increased crush. It’s a small detail, but it improves bearing retention, which is crucial when you’re dealing with the kind of forces that come from high RPMs. And speaking of high RPMs, these bearings have been engineered to eliminate flash plating on the back. This little tweak significantly improves heat transfer and maximizes grip between the bearings and their housing—so you can focus on the road ahead instead of worrying about your internals.

Now, let’s talk about eccentricity. It might sound fancy, but it’s all about compensating for bore distortion at those high speeds. This design helps form hydrodynamic oil films that keep everything lubricated just right. The 3/4 grooved main bearings are another great feature, optimizing the load-carrying surface area and ensuring oil flows smoothly to the conrod bearings. Consistent wall tolerances mean you can maintain reliable clearances, which is a must for any serious build.

And if you're working with performance crankshafts, you’ll love the enlarged ID chamfers on the bearing edges. They accommodate larger fillet radii, making installation a breeze.

As for the specs, these bearings come in sizes like STD, .025, and .25, and they maintain standard oil clearance. They’re made from tri-metal hardened steel backs, giving you the durability you need. Just make sure your shaft size falls between 2.2433 inches and 2.2441 inches, and your tunnel size is within 2.4016 inches to 2.4024 inches for the perfect fit.

These bearings are a solid choice for a variety of Mitsubishi models, including:

• Mitsubishi Eclipse (1990-2011)
• Mitsubishi Galant (1994-2012)
• Mitsubishi Outlander (2003-2015)

If you're looking to boost your engine's performance and reliability, the ACL Race Series Engine Bearings are worth considering. They’ve got the engineering and design to back them up, and trust me, you’ll feel the difference when you hit that throttle.
