What is the advantage of ACL's tri-metal bearing material?

ACL's tri-metal material offers a combination of strength, durability, and embeddability. This means the bearings can withstand high loads while also being able to trap small particles of debris, helping to protect the crankshaft.

Are these bearings suitable for a daily driver?

While these are Race Series bearings built for performance, they can certainly be used in a daily driver if the engine is built for higher performance or if you simply want the added durability. For a stock daily driver, ACL's standard series might be a more common choice, but these will offer improved longevity under stress.

What is the difference between standard size and undersize bearings?

Standard size bearings are meant to be used with a crankshaft that is within factory specifications. Undersize bearings, like 0.010" or 0.020", are used when the crankshaft has been machined down to correct for wear or damage.

Product Details

When you're building a performance engine, especially one that's going to see hard use, the connecting rod bearings are a critical component. These ACL Race Series bearings are built for just that kind of application, offering a well-built solution for Chrysler V8 engines like the 383, 400, and 440. They're designed to handle the increased stresses of performance driving and racing, ensuring your engine's rotating assembly stays properly lubricated and supported.

ACL uses a unique tri-metal material construction in their Race Series bearings. This advanced material provides excellent strength and durability, while also offering good embeddability to help capture any small debris that might get into the oil system. The standard size (STD) means they're intended for use with a crankshaft that's still within factory specifications, without any machining needed. If you're rebuilding a performance Mopar V8, these bearings are a solid choice to ensure reliability under load.

This set includes bearings for all the connecting rods in your engine. Make sure to follow the manufacturer's installation instructions carefully, including proper oil clearances and torque specifications, to get the most out of these performance bearings.
