If you’re looking to push your engine to the limit, let me tell you about the ACL Race Series Engine Bearings. These aren’t just your average bearings; they’re crafted with a unique blend of design, metallurgy, and engineering that really delivers when it comes to high performance. I’ve had my fair share of experiences with bearings, and these stand out, especially when you’re running in higher RPM conditions.

First off, the high-strength overlay plate is thinner, which might sound counterintuitive, but it actually improves fatigue properties. This means they hold up better under stress. And let’s not forget about the hardened steel backs on all the rod bearings. They provide excellent support for the bearing lining and help keep everything snug in the housing. You don’t want your bearings shifting around when you’re pushing your rig hard.

What I really appreciate is the increased crush that enhances bearing retention. You’ll notice that these bearings eliminate flash plating on the back, which is a nice touch. This helps with heat transfer and maximizes grip between the bearings and their housing. If you’ve ever dealt with overheating issues, you know how crucial this is.

And for those of you who love to rev high, the increased eccentricity helps tackle bore distortion, while also assisting in forming those hydrodynamic oil films that keep everything lubricated and running smoothly. The 3/4 grooved main bearings are designed to optimize the load-carrying surface area and ensure oil flows just right to the conrod bearings. It’s all about keeping that engine happy.

Now, let’s talk specs. These bearings come in different sizes—STD, .025, and .25—so you can find the right fit for your setup. They’re made from a blend of aluminum, tin, and silicon, which is a solid combo for durability and performance. The oil clearance is standard, and you’ve got upper and lower half types to choose from. Just to give you an idea of the dimensions, the minimum standard shaft size is 2.7157 inches, and the maximum is 2.7165 inches. The wall thickness at the crown is about 0.0981 inches, which is pretty robust for what you’re getting.

These bearings are a perfect match for a range of applications, including the Toyota Land Cruiser models from 1989-1997, 2002-2007, and 2013-2017. If you’re running a 7M7989 engine, you’ll want to check out the 0.25mm oversized main bearing set from 93-98. It’s all about finding that right fit for your performance needs.

In short, if you’re serious about squeezing every ounce of performance from your engine, these ACL Race Series Engine Bearings are worth considering. They’ve got the features and the durability to keep your engine running strong, even when you’re pushing it to the max.
