If you're diving into the world of high-performance engines, you know how crucial it is to have reliable bearings. The ACL Race Series Engine Bearings really deliver on that front. These aren’t your run-of-the-mill bearings; they’re designed to handle the intense demands of higher RPM situations, making them a solid choice for anyone pushing their engine to the limit. Whether you've got a 4, 6, or 8-cylinder setup, these bearings have you covered.

One of the standout features is the high-strength overlay plate. It's thinner than what you might find on standard bearings, which means better fatigue resistance. This is essential when you're revving high and need your components to hold up under pressure. Plus, the hardened steel backs on all the rod bearings provide extra support for the lining, ensuring they stay put in the housing where they belong.

Speaking of staying put, the increased crush on these bearings really helps with retention. They’ve also eliminated flash plating on the back, which not only improves heat transfer but also enhances the grip between the bearings and their housing. This means you're getting better performance and durability, which is what we all want, right?

Another cool aspect is the increased eccentricity. This feature compensates for bore distortion at high RPMs and aids in forming those all-important hydrodynamic oil films. And when it comes to oil flow, the 3/4 grooved main bearings optimize the load-carrying surface area, ensuring your conrod bearings get the oil they need to perform at their best.

Now, let’s talk specs. These bearings come in sizes like STD, .025, and .25, so you can pick what fits your setup. The oil clearance is standard, and they feature identical halves, which is a nice touch for consistency. The tri-metal hardened steel backs are built to last, and with tight tolerances, you can maintain consistent clearances without any hassle.

For those of you working with performance crankshafts, the enlarged ID chamfers on the bearing edges accommodate larger fillet radii, making installation smoother. The dimensions are spot on, with a minimum standard shaft size of 1.7709 inches and a maximum of 1.7717 inches. The overall length is 0.7283 inches, so you know they’ll fit just right.

In terms of fitment, these bearings are perfect for a range of models, including the Acura Integra (1986-2001) and Honda Civic (1984-2020). If you’re running an ACL Acura D16A1 setup, the 0.25mm oversized high-performance rod bearing set is a game changer.

In short, if you’re serious about performance and reliability, these ACL Race Series Engine Bearings are worth considering. They’ve got the engineering and features that can help your engine reach its full potential.
