Clevite MS-2218P P-Series Main Bearing Set | 2001–2016 GM 6.6L Duramax

The Clevite MS-2218P P-Series Main Bearing Set is a high-quality replacement bearing set for 2001–2016 GM 6.6L Duramax engines. Designed for durability and improved oil control, these tri-metal performance bearings are an excellent choice for stock rebuilds, towing applications, and performance diesel engine builds.

Clevite P-Series bearings are one of the most trusted names in engine performance and are engineered with a full-groove design to maximize oil flow and lubrication to critical engine components. In addition, the high-crush construction provides superior bearing retention while the reduced overlay thickness helps minimize fatigue and surface wear under demanding operating conditions.

Compared to factory bearings, the MS-2218P set offers improved oiling characteristics and durability, making it a popular upgrade for engine builders and diesel performance shops alike.

Please note: this bearing set requires the use of a separate thrust washer set, sold separately.
