What does the 0.010 inch undersize mean for my engine rebuild?

The 0.010 inch undersize means these bearings are designed to fit a crankshaft that has been machined down by 0.010 inches. This is a common practice during engine rebuilding to ensure a perfect fit on journals that may have wear or have been resurfaced.

Are these bearings suitable for a stock engine rebuild?

Yes, while they are part of ACL's Race Series, they are well-suited for stock engine rebuilds where durability and reliable performance are desired. They offer improved wear resistance compared to standard bearings.

What is the primary benefit of using ACL Race Series bearings?

The Race Series bearings are built with a high-performance overlay material and tight tolerances. This combination helps to reduce friction and wear, especially under higher load conditions, contributing to the overall longevity and performance of your engine.
