When it comes to pushing your engine to its limits, you need bearings that can keep up with the demands of high performance. That’s where the ACL Race Series Engine Bearings come into play. These aren’t just any bearings; they’re built to handle the rigors of higher RPMs, making them a solid choice for those who really want to get the most out of their 4, 6, or 8-cylinder engines.

One of the standout features of these bearings is the high-strength overlay plate. It’s thinner than what you might find on standard options, which helps improve fatigue properties. This means they’re less likely to give out when you’re pushing your engine hard. Plus, the hardened steel backs on all rod bearings provide excellent support for the bearing lining, which is crucial for keeping everything in place, especially when the heat is on.

Another great aspect is the increased crush, which really helps with bearing retention. You don’t want your bearings shifting around when you’re making those tight turns or flooring it on the straightaway. And speaking of heat, ACL has eliminated the flash plating on the back of the bearings. This little tweak enhances heat transfer and maximizes grip between the bearings and their housing, so you can count on them to perform under pressure.

High RPMs can cause bore distortion, but these bearings have increased eccentricity to help counteract that. This feature is particularly handy for forming hydrodynamic oil films, ensuring that your engine stays well-lubricated even when the going gets tough. And let’s not forget about the 3/4 grooved main bearings, which optimize the load-carrying surface area and improve oil flow to the conrod bearings. It’s all about keeping everything running smoothly.

With tight, consistent wall tolerances, you can maintain those all-important clearances, which is vital for engine performance. Plus, the enlarged ID chamfers on the bearing edges are designed to accommodate larger fillet radii on performance crankshafts, making installation a breeze.

In terms of specs, these bearings meet or exceed OEM pump flow standards and are individually inspected to ensure they meet pressure and flow requirements. You’re also covered with a twelve-month, 12,000-mile warranty, so you can hit the track with confidence. With TSI6949 and ISO certifications backing them up, you know you’re getting a reliable product.

The die-cast ADC-12 aluminum housing adds strength without the extra weight, and the steel copper alloy gerotor sets are built for dependable service. Tight tolerances mean you’ll get optimum pressure and flow performance every time.

These bearings fit a range of models, including the Mitsubishi Mirage from 1992 to 2003 and 2014 to 2016, as well as the Mitsubishi Eclipse and Galant with the 4G63 and 4G61 engines. If you’re looking to upgrade your oil pump, the OPMB1096 is a solid choice for the 89-92 Galant Turbo too.

In short, if you’re serious about performance, these ACL Race Series Engine Bearings are worth considering. They’ve got the engineering and design to back up your passion for speed.
