When it comes to pushing your engine to the limit, you want bearings that can keep up with the demands of high performance. That’s where the ACL Race Series Engine Bearings come into play. These bad boys are crafted with a unique blend of design, metallurgy, and engineering that really sets them apart. If you’ve got a 4, 6, or 8-cylinder engine, you’ll find the right fit here.

What makes these bearings stand out? For starters, they feature a high-strength overlay plate that’s thinner than your average bearing. This reduction in thickness doesn’t just save weight; it actually improves fatigue properties, letting you rev higher without worrying about wear. Plus, the hardened steel backs on all the rod bearings provide excellent support for the lining, ensuring they stay put even under intense conditions.

One of the standout features is the increased crush, which helps with bearing retention. This is crucial when you’re pushing your engine hard—nobody wants to deal with bearings that slip or move around. And if you’re concerned about heat, ACL has you covered. They’ve eliminated flash plating on the backs of the bearings, enhancing heat transfer and maximizing grip between the bearings and their housing. This means better performance and longevity, especially when you’re really pushing those RPMs.

Speaking of high RPMs, the increased eccentricity is a game changer. It compensates for any bore distortion at high speeds, which is essential for forming those hydrodynamic oil films that keep everything running smoothly. You’ll also appreciate the 3/4 grooved main bearings, which optimize the load-carrying surface area and ensure oil flows efficiently to the conrod bearings.

Consistency is key in performance builds, and these bearings deliver tight, consistent wall tolerances to help you maintain precise clearances. And if you’re working with performance crankshafts, the enlarged ID chamfers on the bearing edges are designed to accommodate larger fillet radii, making installation a breeze.

Now, let’s talk specs. You can get these bearings in standard sizes, .025, and .25. They maintain standard oil clearance with identical halves, and the tri-metal construction with hardened steel backs means they’re built to last. The minimum standard shaft size is 1.889 inches, maxing out at 1.8898 inches, while the tunnel sizes range from 2.008 to 2.0088 inches. With a maximum wall thickness at the crown of 2.0088 inches and an overall length of 0.6063 inches, these bearings are designed for serious performance.

So, if you’re looking to upgrade your Lexus V8—whether it’s the 1UZFE, 2UZFE, or 3UZFE—this standard size high-performance rod bearing set (8B8091H-STD) is worth considering. They’re not just bearings; they’re a step towards unlocking your engine’s full potential.
