If you're looking to push your engine to the limit, you’ll want to check out the ACL Race Series Engine Bearings. These aren’t just your average bearings; they’re designed specifically for high-performance applications, making them a solid choice for anyone who’s serious about their ride. Whether you’re rocking a 4, 6, or 8-cylinder setup, these bearings are built to handle the kind of RPMs that would make lesser components sweat.

What sets these bearings apart? For starters, they feature a high-strength overlay plate that’s thinner than what you’d find in standard bearings. This isn’t just a design choice; it actually improves fatigue resistance, which is crucial when you’re pushing your engine hard. Plus, the hardened steel backs on all rod bearings provide extra support for the bearing lining, ensuring they stay put in the housing even when the going gets tough.

One of the standout features is the increased crush, which helps with bearing retention. You won’t have to worry about them shifting around during those intense drives. They’ve also eliminated flash plating on the back, which enhances heat transfer. This means better performance and longevity, as the bearings can grip the housing more effectively.

Now, if you’re revving high, you’ll appreciate the increased eccentricity. This design compensates for any bore distortion, which is important for forming hydrodynamic oil films. And speaking of oil, the 3/4 grooved main bearings optimize the load-carrying surface area, ensuring that oil flows smoothly to the conrod bearings. It’s all about keeping everything lubricated and running smoothly at those high RPMs.

These bearings come with tight, consistent wall tolerances, helping you maintain those all-important clearances. They even feature enlarged ID chamfers where necessary to accommodate larger fillet radii on performance crankshafts. It’s this attention to detail that makes a real difference when you’re building or tuning your engine.

Now, let’s get into some specs. You’ve got options with sizes like STD, .025, and .25, and the oil clearance is standard. They’re half-type, meaning you’ll get upper and lower halves, and they’re made from tri-metal with hardened steel backs. For those of you tinkering with a Hyundai Genesis from 2009 to 2016, these bearings are a perfect fit for the G4KF 2.0T engine. Just make sure you’re within the shaft size limits of 2.0450in to 2.0457in and the tunnel sizes of 2.2047in to 2.2054in.

In short, if you’re looking to enhance your engine’s performance and reliability, the ACL Race Series Engine Bearings are worth considering. They’re built for the real world, where performance matters, and you can trust them to keep your engine running strong.
