If you’re diving into the world of performance engines, you know that every little detail counts. That’s where the ACL Race Series Engine Bearings come into play. These aren’t just any bearings; they’re crafted with a blend of smart design, solid metallurgy, and real engineering know-how. Designed for high RPM conditions, these bearings are perfect for anyone pushing their 4, 6, or 8-cylinder engine to the limits.

One of the standout features is the high-strength overlay plate. It’s thinner than what you might find elsewhere, which is a game-changer for fatigue resistance. You want your engine to perform, and these bearings help it do just that. Plus, the hardened steel backs on all the rod bearings add an extra layer of support, ensuring that the bearing lining stays in place where it belongs. No one wants their bearings shifting around, especially when you’re revving up.

Speaking of staying put, the increased crush improves bearing retention, so you can rest easy knowing these bearings are locked in tight. And let’s talk about heat transfer—ACL has eliminated flash plating on the back of the bearings. This means better heat dissipation and a stronger grip between the bearings and the housing. When you’re pushing your engine hard, every degree counts.

Another cool feature is the increased eccentricity. This helps compensate for bore distortion at high RPMs, which is crucial for forming those hydrodynamic oil films that keep everything running smoothly. And don’t overlook the 3/4 grooved main bearings; they optimize the load-carrying surface area and enhance oil flow to the conrod bearings. It’s all about keeping that oil moving where it needs to be.

With tight, consistent wall tolerances, you can maintain reliable clearances, ensuring that your setup is as precise as it gets. And if you’ve got a performance crankshaft with a large fillet radius, the enlarged ID chamfers on the bearing edges will accommodate that perfectly.

Now, let’s get into some specs. These bearings come in standard sizes as well as .025 and .25 oversizes, giving you options based on your build. The oil clearance is standard, and they feature identical halves, which is a nice touch for ease of installation. Made from tri-metal with hardened steel backs, these bearings can handle some serious stress.

As for fitment, they’re compatible with a range of popular models, including:

• Lexus GS300 (1993-2006)
• Lexus SC300 (1992-2000)
• Toyota Supra (1986-2002)

So, if you’re looking to boost your engine’s performance and reliability, these ACL Race Series Engine Bearings are worth considering. They’re built for the real world and ready to handle whatever you throw at them.
