What does the +0.25mm size mean for these bearings?

The +0.25mm designation indicates that these bearings are slightly larger than standard size. They are designed to be used when the crankshaft journals have been machined down by 0.25mm (approximately 0.010 inches) to correct for wear or damage.

Are these bearings suitable for high-performance or racing engines?

These bearings are described as ideal for low to medium-load engines. For high-performance or racing applications with very high RPMs and heavy loads, you might consider a different bearing material or series from King Engine Bearings.

What is the material composition of these bearings?

These bearings are made from a bi-metal aluminum material and feature a lead-free, environmentally safe composite coating. This construction is chosen for its performance in less demanding engine conditions.
