ACL High Performance Rod Bearing Set .25 Oversized for Subaru FB20/FB25 Engine - 4B8325H-.25

If you're diving into the world of high-performance engines, you know that the right components 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 meticulously for those who push their engines to the limit. Whether you’re running a 4, 6, or 8-cylinder setup, these bearings are built to handle the high RPMs that come with serious driving.

One of the standout features is the high-strength overlay plate. It’s thinner than what you might find in standard bearings, which means better fatigue resistance when you’re really pushing your engine. And let’s talk about the hardened steel backs on the rod bearings—this helps keep everything stable and ensures the lining stays exactly where it needs to be. You’ll appreciate the increased crush too; it helps keep the bearings securely in place, which is crucial when you're racing or just enjoying a spirited drive.

Another thing I love is the removal of flash plating on the back of the bearings. This isn’t just a minor tweak; it significantly boosts heat transfer and helps maintain a solid grip in the housing. When you’re at high RPMs, the last thing you want is for your bearings to slip. Plus, with the increased eccentricity, you’ll find that these bearings compensate for any bore distortion, which is a common issue at higher speeds. They also support the formation of hydrodynamic oil films, keeping everything lubricated and running smoothly.

And for those who really want to optimize their setup, the 3/4 grooved main bearings are a game changer. They maximize the load-carrying surface area and ensure that oil flows efficiently to the conrod bearings, which is essential for performance. The tight, consistent wall tolerances mean you can maintain clearances that are spot on, which is what you need for reliability.

Plus, for those performance crankshafts out there, the enlarged ID chamfers on the bearing edges are a thoughtful addition. They accommodate larger fillet radii, making installation easier and more effective. With sizes available in STD, .025, and .25, you can find the perfect fit for your setup.

So if you’re looking to bring your Subaru FB20/FB25 to the next level, consider the 4B8325H-.25 ACL High Performance Rod Bearing Set. These bearings deliver the durability and performance that serious drivers expect, and they’re ready to take your engine to new heights.
