What does the '+0.030' size mean for these bearings?

The '+0.030' indicates that these bearings are 0.030 inches larger in diameter than standard size. They are intended for use when the engine's crankshaft has been machined down by 0.030 inches to remove wear or damage.

What is the advantage of the Tri-M+ Enhanced Babbit Overlay?

The Tri-M+ overlay is a specialized layer that helps with oil retention and provides improved wear resistance. This is important for ensuring the bearings last and protect the crankshaft effectively.

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

These bearings are described as ideal for medium-load engines. For high-performance or racing applications with significantly higher loads and RPMs, it's recommended to consult King Engine Bearings' specific product lines designed for those demanding uses.
