ACL Subaru/Scion FA20 Standard Size High Performance Rod Bearing Set 2013-2022 - 4B8310H-STD

If you're serious about pushing your engine to its limits, you’ll want to take a good look at these ACL Race Series Engine Bearings. I’ve been around the block with a few performance builds, and I can tell you—these bearings are a game changer. They’re engineered to handle those higher RPMs without breaking a sweat, making them a solid choice for anyone looking to get the most out of their 4, 6, or 8-cylinder setups.

What really stands out about these bearings is the thoughtful design and materials. The overlay plate is tough yet slim, which means it can take on a lot of stress without wearing out quickly. Plus, the hardened steel backs on the rod bearings give you that extra peace of mind, ensuring the bearing lining stays put and doesn’t get pushed around. You’ll appreciate the increased crush that helps hold everything tight in the housing, especially when the engine’s really revving.

One of my favorite features is the elimination of flash plating on the back of the bearings. This little tweak improves heat transfer and enhances the grip between the bearings and the housing, which is crucial when you’re running at high speeds. And let’s not forget about the increased eccentricity—it really helps with bore distortion at high RPMs, allowing for better hydrodynamic oil films to form. It’s these details that make a difference when you’re racing or just enjoying a spirited drive.

When it comes to oil flow, the 3/4 grooved main bearings are designed to optimize the load-carrying surface area, ensuring that oil gets to where it needs to be—specifically, the conrod bearings. The tight wall tolerances mean you can maintain consistent clearances, which is key for performance. And if you’re working with performance crankshafts, the enlarged ID chamfers accommodate those larger fillet radii perfectly.

As for specs, you can find these bearings in sizes like STD, .025, and .25, giving you options to fit your specific setup. Trust me, the reliability you get with ACL Race Series engine bearings can’t be overstated, especially when you’re pushing your engine to its limits.

These bearings fit a range of vehicles, including the Scion FRS from 2013 to 2016 and the Subaru WRX from 2002 to 2022. If you’re looking for a high-performance rod bearing set, the 4B8310H-STD ACL Subaru/Scion FA20 is definitely worth considering. They’re built to last and designed to perform, so you can focus on enjoying the drive.
