What does the .010X Oversized designation mean for these bearings?

The .010X Oversized designation means these bearings are slightly larger than standard size. This is typically used when the engine's crankshaft journals have been machined down by 0.010 inches to account for wear or to achieve a specific clearance.

What is the PMaxBlack overlay and Radialock technology?

PMaxBlack is a specialized overlay that King Engine Bearings uses to enhance the bearing's ability to handle higher loads. Radialock is a feature designed to help the bearing maintain its proper shape and fit during installation, ensuring optimal performance.

What is the typical lifespan of these bearings?

The lifespan of engine bearings depends heavily on proper installation, oil quality and change intervals, and the operating conditions of the engine. King Engine Bearings are well-built, but regular maintenance is key to maximizing their service life.
