If you’re serious about performance, you know that the heart of your engine needs top-notch bearings to handle the heat and stress of high RPMs. That’s where these ACL Race Series Engine Bearings come into play. They’re not just another part; they’re engineered with a unique blend of design and metallurgy that really makes a difference when you're pushing your ride to the limit.

These bearings are built tough. The high-strength overlay plate is thinner than what you’d find in standard bearings, which means it’s got better fatigue properties. That’s crucial when you’re wringing out every last bit of power. Plus, the hardened steel backs on all rod bearings provide solid support for the lining and help keep everything snug in the housing. No more worrying about slippage when you’re revving hard.

One of the standout features is the increased crush for better retention. This means they stay put, even under heavy loads. Oh, and they’ve done away with flash plating on the back. Why? Because it improves heat transfer and maximizes the grip between the bearings and the housing. That’s a win-win for performance and reliability.

These bearings also come with increased eccentricity. This little tweak helps compensate for bore distortion at high RPMs, which is vital for forming those hydrodynamic oil films that keep everything running smoothly. You’ll appreciate the 3/4 grooved main bearings too; they optimize the load-carrying surface area and ensure oil flows just right to the conrod bearings. Consistent wall tolerances mean you can trust your clearances, which is a big deal when you’re tuning for precision.

Now, let’s talk specs. You’ve got options with sizes like STD and .25, and standard oil clearance. These bearings are identical halves, made from tri-metal with hardened steel backs. They fit snugly on shafts ranging from 1.9680 inches to 1.9685 inches, and the tunnel sizes are right in the sweet spot too, measuring between 2.1139 inches and 2.1145 inches. With a max wall at the crown of 0.0723 inches and an overall length of 0.923 inches, these bearings are designed to fit perfectly in your engine.

These bearings are compatible with several Alfa Romeo models, including:

• Alfa Romeo Giulia (2017-2021)
• Alfa Romeo Giulietta (2012-2020)
• Alfa Romeo GT (2007-2008)

If you’re looking to seriously upgrade your engine’s internals, these ACL Race Series Engine Bearings are a solid choice. They’re built for those who know that every detail counts when you’re chasing performance.
