What does the '1.0' size designation mean for these bearings?

The '1.0' in the part number indicates that these are 1.0 undersize bearings. This means they are designed to be used when the crankshaft journals have been machined down by 0.010 inches to account for wear or damage.

What is the advantage of the tri-metal copper-based material with Babbitt overlay?

The tri-metal construction offers a strong foundation, while the copper-based material and enhanced Babbitt overlay provide excellent conformability and embeddability. This helps to maintain a consistent oil film and reduce friction, which is important for engine longevity.

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

King Engine Bearings rates these bearings as ideal for medium-load engines. For high-performance or racing applications, it's always best to consult King's specific product lines designed for those demanding conditions.
