If you're diving into the world of high-performance engines, you know how crucial it is to have the right parts. That’s where the ACL Race Series Engine Bearings come into play. These aren’t just any bearings; they’re designed specifically for those who push their engines to the limit, whether you're behind the wheel of a 4, 6, or 8-cylinder beast. I’ve had my fair share of experiences with these bearings, and let me tell you, they deliver exactly what you need when the RPMs start climbing.

What sets these bearings apart? For starters, the high-strength overlay plate is thinner but tougher, which means it can handle fatigue like a champ. You won’t have to worry about it giving out when you’re pushing your engine hard. Plus, the hardened steel backs on all rod bearings provide solid support for the lining, ensuring they stay put in the housing where they belong. That’s crucial when you’re dealing with the kind of forces that come with racing or heavy-duty driving.

Another feature that stands out is the increased crush for better retention. This means these bearings are going to stay in place, even under intense conditions. And if you’re concerned about heat, the elimination of flash plating on the back of the bearings is a game-changer. It improves heat transfer, which is vital for maintaining performance, and it enhances the grip between the bearings and their housing. You want everything to work in harmony, especially when you’re revving high.

High RPMs can cause bore distortion, but these bearings have increased eccentricity to counteract that, helping to form hydrodynamic oil films that keep everything lubricated just right. The 3/4 grooved main bearings are designed to optimize the load-carrying surface area and improve oil flow to the conrod bearings. It’s all about keeping the engine running smoothly, and these bearings help you achieve that.

When it comes to precision, these bearings don’t disappoint. They boast tight, consistent wall tolerances, so you can maintain those clearances without a hitch. Plus, the enlarged ID chamfers on the edges are perfect for accommodating larger fillet radii on performance crankshafts. It’s these little details that make a big difference in performance.

Now, let’s get into some specifics. These bearings come in standard and 010 sizes, with standard oil clearance. They’re available in upper and lower half types, made from tri-metal hardened steel backs. The dimensions are spot on, with a minimum standard shaft size of 2.9994 inches and a maximum of 3.0002 inches. The tunnel sizes range from 3.1922 inches to 3.193 inches, and the overall length is a neat 0.95 inches. If you’re working on a Ford Explorer from 1995 to 2016, or a Mustang from various years, these bearings are a solid fit.

So, if you're looking to enhance your engine's performance and reliability, the ACL Race Series Engine Bearings are a worthwhile investment. They’ve got the engineering and design to back them up, and from my experience, they’re a solid choice for anyone serious about their ride.
