If you're serious about performance, you know that engine bearings can make or break your ride. The ACL Race Series Engine Bearings are where design, metallurgy, and engineering come together, and trust me, they deliver big time. These aren’t just any bearings; they’re built to handle those high RPMs you crave, whether you’re running a 4, 6, or 8-cylinder setup.
Let’s dive into what makes these bearings stand out. First off, the high strength overlay plate is thinner, which means better fatigue resistance. You’ll appreciate that when you’re pushing your engine to its limits. And speaking of limits, the hardened steel backs on the rod bearings really help support the lining, keeping everything snug in the housing. No one wants bearings that slip around, right?
Another cool feature is the increased crush, which locks those bearings in place even better. Plus, they’ve ditched the flash plating on the back. This isn’t just a cost-cutting move; it actually helps with heat transfer and ensures a solid grip in the housing. When you’re revving high, you want every bit of oil to flow smoothly, and these bearings are designed to do just that.
With an increased eccentricity, you’re getting a little extra help to deal with bore distortion at high RPMs. This means you’ll have better hydrodynamic oil films forming, which is crucial for keeping everything lubricated under stress. The 3/4 grooved main bearings are another smart touch, optimizing the load-carrying surface area and ensuring oil flows just where you need it—straight to the conrod bearings.
And let’s not forget about the tight wall tolerances. Consistent clearances are key, especially if you’re tuning your engine for peak performance. They’ve even enlarged the ID chamfers on the edges to accommodate those larger fillet radii found on performance crankshafts. It’s the little details that count, right?
Now, for the specs: you’ve got sizes ranging from STD to .025 and .25, with standard oil clearance. They come in identical halves and are made from tri-metal with hardened steel backs. The dimensions fit a variety of Mazda models, including:
- Mazda CX-7 (2007-2012)
- Mazda 3 (2004-2021)
- Mazda 6 (2003-2018)
So if you’re looking for a high-performance rod bearing set that won’t let you down, the ACL Race Series is a solid choice. Grab a set and feel the difference on your next drive!
