ACL High Performance Main Bearing 0.25mm Oversized for Subaru EJ20/EJ22/EJ25 1990-2017
$86.45

If you're looking to push your engine to the limit, you might want to check out the ACL Race Series Engine Bearings. These aren't just any bearings; they’re built for those who demand high performance, especially in those adrenaline-pumping RPM ranges. When you're out there on the track or tackling tough trails, you need something that can really hold up. That’s where these bad boys come in.

The design is pretty impressive. They’ve got a high-strength overlay plate that’s thinner than what you’d find in standard bearings, which means they handle fatigue like a champ. Plus, the hardened steel backs on the rod bearings give that extra support to the lining, ensuring they stay put in the housing. You won't have to worry about them shifting around when things get intense.

One of the standout features is the increased crush, which helps with bearing retention. This is crucial when you're pushing the limits of your engine. They’ve also done away with flash plating on the back, which not only improves heat transfer but also maximizes the grip between the bearings and the housing. Trust me, when you’re revving high, every little detail matters.

What’s more, they’ve increased the eccentricity to handle bore distortion at high RPMs. This helps in forming those hydrodynamic oil films that are essential for keeping everything lubricated and running smoothly. And if you’re concerned about oil flow, the 3/4 grooved main bearings are designed to optimize the load-carrying surface area, ensuring your conrod bearings get the oil they need.

Consistency is key in performance, and these bearings deliver with tight wall tolerances that help maintain clearances. They’ve even enlarged the ID chamfers where necessary to accommodate those large fillet radii on performance crankshafts—just another detail that shows they’ve thought of everything.

As for specs, you can get these in various sizes (STD, .025, .25, 0.5), with standard oil clearance and identical halves. They’re made from tri-metal with hardened steel backs, and they fit a range of Subaru models from the Forester to the Impreza, Legacy, and Outback, covering years from 1990 to 2017. So whether you're working on an EJ20, EJ22, or EJ25, these bearings are ready to take your setup to the next level.

In short, if you're serious about performance, the ACL Race Series Engine Bearings are worth considering. They’re built to last and designed for those who really know what they’re doing under the hood.
