What does the +0.50mm sizing mean for these bearings?

The +0.50mm designation indicates that these bearings are slightly larger than standard size. This is common in engine rebuilding to achieve the correct oil clearance between the crankshaft and the main journals, especially if the journals have been machined.

What is the Tri-M+ babbitt overlay?

The Tri-M+ overlay is an enhanced layer applied to the bearing surface. It's designed to improve the bearing's ability to embed debris and provide a smoother running surface, contributing to longer bearing life.

Are these bearings suitable for heavy towing applications?

These bearings are described as ideal for medium-load engines. While Duramax engines are robust, for extremely heavy-duty or constant high-load towing, it's always best to consult with a professional engine builder to ensure all components meet your specific operational demands.
