ACL Engine Bearings 0.25 Oversized Rod Bearing Set for GM Cadillac Commodore CTS Malibu G6 G8 3.2L 3.6L - 6B2270A-.25

If you're diving into the world of high-performance engines, you’ve probably heard about ACL Race Series Engine Bearings. These bad boys are designed for those who want to push their engines to the limit, especially if you're running a 4, 6, or 8-cylinder setup. I’ve had my fair share of engine builds, and trust me, these bearings deliver the kind of reliability and performance you need when things get revved up.

What really stands out is the unique blend of design and metallurgy. The high-strength overlay plate is thinner than what you might find in standard bearings, which means it can handle the fatigue that comes with those higher RPMs. And let’s be real, if you’re pushing your engine hard, you want bearings that won’t let you down.

The hardened steel backs on the rod bearings are a game changer. They not only support the bearing lining but also help keep everything locked in place in the housing. You’ll appreciate the increased crush, too—it really helps with bearing retention, especially when you’re putting your engine through the wringer.

One feature I love is the elimination of flash plating on the back. This isn’t just some fancy detail; it actually improves heat transfer and maximizes the grip between the bearings and the housing. When you’re in the thick of it, every little bit counts, right? Plus, the increased eccentricity helps counteract any bore distortion you might experience at high RPMs, which is crucial for forming those hydrodynamic oil films that keep everything running smoothly.

And if you’re wondering about oil flow, the 3/4 grooved main bearings are designed to optimize the load-carrying surface area. This means more oil gets to your conrod bearings, which is exactly what you want when you’re pushing the limits. You’ll also appreciate the tight, consistent wall tolerances that help maintain clearances, keeping your engine happy.

As for the specifics, you’ve got options with sizes like STD and 0.25. The 6B2270A-.25 set is perfect for GM and Cadillac models like the Commodore, CTS, Malibu, G6, and G8, especially those 3.2L and 3.6L HFV6 engines from 2004 onward. If you’re serious about performance, these bearings are definitely worth considering.
