Product Description

The **Clevite MS2218H** is a performance main bearing set engineered for the GM 6.6 L Duramax diesel engine - covering many model years from 2001 through 2013. Built with Clevite's H-Series technology, it's designed for engines that run under heavy load or at higher RPMs, offering greater durability and reliability.

The tri-metal design combines a solid steel backing with a copper-lead core and a precision overlay to deliver excellent strength, fatigue resistance, and oil film retention. High crush ensures the bearings seat securely, while enlarged edge chamfers help accommodate crankshaft fillet radii without compromising strength.

These bearings are a go-to for build-ups like performance towing, competition diesel builds, or any high-stress Duramax application where standard bearings might be pushed to their limits. They provide a robust foundation for the crank to run smoothly and reliably under demanding conditions.
