If you’re serious about your engine performance, you know that the right bearings 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 designed for those who push their engines to the limit—think higher RPMs and serious power. Whether you’re running a 4, 6, or 8-cylinder setup, these bearings have got you covered.
So, what sets these apart? For starters, the high-strength overlay plate is thinner, which means it’s got improved fatigue properties. This is crucial when you’re revving high and need that extra durability. Plus, every rod bearing comes with hardened steel backs. This not only supports the bearing lining but also helps keep everything snug in the housing, so you don’t have to worry about any slips while you’re tearing up the road.
Speaking of snug fits, the increased crush on these bearings enhances retention, ensuring they stay put even under the most intense conditions. And forget about flash plating on the back; that’s been eliminated to boost heat transfer. This means your bearings can handle the heat and keep performing like a champ. The increased eccentricity is another neat feature, compensating for any bore distortion at high RPMs and helping form those all-important hydrodynamic oil films.
Now, let’s talk about the 3/4 grooved main bearings. They optimize the load-carrying surface area and oil flow to the conrod bearings, which is key for keeping everything lubricated and running smoothly. Plus, the tight wall tolerances help you maintain consistent clearances, which is essential for performance engines. And if you’ve got a performance crankshaft, the enlarged ID chamfers on the bearing edges accommodate larger fillet radii, making installation a breeze.
As for the specs, these bearings are made by NDC and are tough as nails when it comes to abrasion, load, impact, and heat resistance. You can choose from sizes like STD (.000") or 010 (.010"), so you can find the perfect fit for your setup.
These bearings are a solid choice for anyone running a Mazda 626 from 1988 to 2002, specifically the 6B8350-.50 ACL Mazda V6 (2497-2954CC) with a 0.50mm oversized conrod rod bearing set from '88 to '98. If you’re looking to upgrade your ride and really want to feel the difference, these bearings are a no-brainer.
