If you're diving into the world of high-performance engines, you’ve probably heard about ACL Race Series Engine Bearings. These aren’t just any bearings; they’re built for those who really push their engines to the limits. With a unique blend of design, metallurgy, and engineering, these bearings are designed to handle the kind of RPMs that get your heart racing.
What sets these bearings apart? For starters, they feature a high-strength overlay plate that’s thinner than what you might find on standard bearings. This isn’t just for show—this design improves fatigue properties, which means they can take a beating without giving up. And if you’re running a performance setup, you’ll appreciate the hardened steel backs on all the rod bearings. This adds extra support to the bearing lining and helps keep everything snug in its housing. Trust me, that’s crucial when you’re pushing your engine hard.
But it doesn’t stop there. The increased crush on these bearings enhances retention, so you won’t have to worry about them shifting around when the power kicks in. Plus, they’ve eliminated flash plating on the back, which optimizes heat transfer and maximizes grip between the bearings and the housing. This is especially important as you ramp up the RPMs, where every bit of efficiency counts.
Now, let’s talk about eccentricity. These bearings have been designed with increased eccentricity to compensate for bore distortion at high RPMs. This helps form those all-important hydrodynamic oil films that keep everything running smoothly. And if you’re using them in a performance setup, the 3/4 grooved main bearings are a game changer—they optimize the load carrying surface area and ensure oil flows just right to the conrod bearings.
Consistency is key, and with tight wall tolerances, you can maintain precise clearances without the guesswork. Plus, they’ve got enlarged ID chamfers on the edges where it counts, accommodating those larger fillet radii on performance crankshafts. It’s all about making sure everything fits together perfectly.
As for the specs, you’re looking at a standard size of 4B2260HX-STD, designed for Ford Duratorq 2.0L, 2.2L, and 2.4L Diesel engines. With an oil clearance of just .001 inches, these bearings are ready to take your engine to the next level.
In short, if you’re serious about performance, you’ll want to give these ACL Race Series Engine Bearings a shot. They’re built to last and designed for those who demand the best from their engines.
