01-16 GM 6.6L Duramax Mahle P-Series Main Bearing Set (.25mm Undersize)

The Clevite MS-2218P-.25MM P-Series Main Bearing Set is a superior-quality replacement for the burnt-up bearings in your 2001-2016 GM 6.6L Duramax. These high performance Clevite P-Series bearings are the longest running series of Clevite bearings with the main bearings being full grooved for superior oil flow for lubrication. These bearings offer a high crush for superior retention, and a reduced overlay thickness to minimize overlay fatigue, oftentimes called as hen tracking. Manufactured for narrow bearing contact patterns and to provide improved oiling to the main bearings, this main bearing set is a great improvement over OE GM bearings.
