ACL Race Series Mini Inline 4 Engine Bearings 3M2205HX-STD for 1983+ Applications - 3M2205HX-STD

If you're diving into the world of high-performance engines, you know that the right components 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 crafted for those who push their engines to the limit, designed to handle the kind of RPMs that would make lesser parts sweat. Whether you’re working on a 4, 6, or 8-cylinder setup, these bearings have got you covered.

What sets these bearings apart? For starters, the high-strength overlay plate is thinner than what you might find elsewhere, which really amps up the fatigue resistance. This means you can rev higher without worrying about premature wear. And let’s talk about the hardened steel backs on the rod bearings. They provide solid support for the lining and help keep everything locked in place, even when the engine is working hard.

Another cool feature is the increased crush, which enhances bearing retention. You want your bearings to stay put, especially when you're pushing your ride to its limits. Plus, they’ve ditched the flash plating on the back, which not only improves heat transfer but also maximizes grip between the bearings and their housing. That’s a win-win if you ask me.

When you’re running at high RPMs, distortion can be an issue. These bearings have increased eccentricity to help counter that, promoting the formation of hydrodynamic oil films. And for those main bearings, they’ve got a 3/4 groove design that optimizes the load-carrying surface area and ensures oil flows smoothly to the conrod bearings. Consistency is key, and the tight wall tolerances help you maintain those all-important clearances.

Need to fit those bearings onto a high-performance crankshaft? No problem. The enlarged ID chamfers on the edges are designed to accommodate larger fillet radii, so you won’t run into any snags there.

Now, when it comes to specs, these bearings don’t disappoint. They’re built to withstand the demands of higher RPMs, blending cutting-edge design, metallurgy, and engineering. You’ll find sizes available like STD, 001, and 010, ensuring a fit for your specific application.

For anyone working on an ACL BMC Mini Inline 4 (from 1983 up), the 3M2205HX-STD rod bearing is a standout choice. It offers extra oil clearance, which is crucial for keeping things running smoothly under pressure. If you're serious about performance, these bearings are worth a look.
