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

The +0.25mm sizing indicates that these bearings are slightly larger than standard size. This is typically used when the crankshaft journals have been machined down by 0.25mm during an engine rebuild to ensure a proper fit and oil clearance.

What is the Tri-M+ Babbitt overlay?

Tri-M+ is an enhanced Babbitt overlay developed by King Engine Bearings. It's designed to improve the bearing's performance and durability, especially under higher load conditions, by providing a more resilient surface.

Are these bearings suitable for a stock engine rebuild?

Yes, these bearings are built for medium to high-load engines and feature a tri-metal construction with an enhanced Babbitt overlay, making them a well-built option for many engine rebuilds, including those that may see heavier use.
