What material are these main bearings made from?

These main bearings are constructed from a tri-metal copper-based material. They also feature King's Tri-M+ enhanced babbit overlay for improved performance and durability.

Are these bearings suitable for high-performance or heavily modified Duramax engines?

This set is ideal for medium-load engines. For heavily modified or extreme performance applications, it's always best to consult with a specialist or the manufacturer to ensure the bearings meet your specific engine's demands.

What is the purpose of the babbit overlay on these bearings?

The enhanced babbit overlay helps to improve the bearing's ability to conform to the crankshaft journal, which can lead to better oil distribution and reduced friction. This contributes to overall engine health and longevity.
