The Mahle Clevite MS-2269P is a professional-grade main bearing set engineered for the high-torque, high-load environment of the Ford 6.4L Powerstroke. As part of the legendary P-Series, these bearings are the go-to choice for engine builders who require more fatigue resistance than a standard aluminum bearing can provide.
Utilizing Mahle’s specialized tri-metal construction, these bearings are designed to handle the massive cylinder pressures and "crankshaft whip" inherent to high-performance diesel engines.
TM-77 Tri-Metal Construction: Features a high-strength steel backing, a copper-lead intermediate layer, and a lead-tin-copper overlay. This combination provides the ideal balance of strength, conformability, and embeddability
Superior Load Capacity: Engineered to withstand the extreme "hammering" of diesel combustion, making it perfect for heavy-duty towing, work trucks, and street performance builds.
Excellent Embeddability: The specialized overlay allows the bearing to safely "absorb" small debris particles that might otherwise score your crankshaft journals.
High Crush Factor: Designed for a secure press-fit into the engine block and main caps, ensuring maximum heat transfer and preventing bearing spin under stress.
Precision Manufacturing: Produced to the industry’s tightest wall thickness tolerances to ensure consistent oil clearances across all journals.

Builder’s Note: While the P-Series is perfect for the vast majority of 6.4L builds, if you are building a dedicated competition or "sled pull" engine with an aftermarket crankshaft, you may want to consider the H-Series (MS-2269H) for its specialized high-RPM chamfering.
