If you're serious about getting the most out of your engine, you’ll want to check out these ACL Race Series Engine Bearings. These babies are designed with a unique blend of engineering and metallurgy that really caters to the demands of high-performance driving. Whether you're pushing your ride to the limits on the track or just want a little extra reliability on the street, these bearings have got your back.
What sets these apart? For starters, the high-strength overlay plate is thinner, which helps reduce fatigue—perfect for those high RPM runs. Plus, every rod bearing comes with hardened steel backs, giving you that extra support where it counts. This means they stay put in the housing, so you don’t have to worry about any slipping while you’re out there having fun.
One of the standout features is the increased crush. This isn’t just a number; it translates to better bearing retention, which is crucial when you’re really pushing your engine. And forget about flash plating on the back; that’s out. This design choice improves heat transfer, ensuring that your bearings stay cool and maintain a solid grip in their housing.
When you're revving high, bore distortion can be a real issue. That’s why these bearings come with increased eccentricity to help manage that distortion and support the formation of hydrodynamic oil films. The 3/4 grooved main bearings optimize the load-carrying surface area, which means better oil flow to the conrod bearings. Tight wall tolerances help keep your clearances consistent, so you can trust that everything is running smoothly.
And if you’ve got a performance crankshaft, you’ll appreciate the enlarged ID chamfers on the bearing edges. They’re designed to accommodate larger fillet radii, which is a nice touch for those of us who like to push the envelope.
