What is the difference between Race Series and standard ACL bearings?

ACL Race Series bearings use a specialized overlay material that offers improved fatigue resistance compared to standard bearings. This makes them better suited for high-stress applications like racing or performance street engines.

Are these bearings a standard size?

Yes, this set is standard size (STD). They are designed to be used with a crankshaft that is at its original factory size and has not been machined undersize.

What else might I need when installing main bearings?

When installing main bearings, you'll need to use a quality assembly lube to protect the bearing surfaces during initial startup. It's also crucial to follow the manufacturer's torque specifications precisely for all main bearing caps.

Product Details

ACL has been making engine bearings for decades, and this Race Series Main Bearing Set for your Ford V8 is one of their staples. These bearings are built for engines that see a lot of action, whether it's for racing or just a high-performance street build. They're designed to handle the extra stress and heat that comes with more powerful V8s like the 351M, 351W, and 400 cubic inch engines.

The Race Series bearings use a special overlay material that's tougher and more resistant to fatigue than standard bearings. This means they can keep your crankshaft supported even when you're pushing the engine hard. They're a standard size, so they're meant to be used with a crankshaft that hasn't been machined undersize. If you're rebuilding a performance Ford V8, these bearings are a solid choice to ensure your bottom end stays strong.

This set includes all the main bearings you'll need for your engine. When you're installing these, make sure to follow the manufacturer's torque specifications and use the correct assembly lube to get the best performance and longevity out of them.
