The Mahle Clevite MS-2269H is a high-performance, competition-grade main bearing set engineered for the Ford 6.4L Powerstroke. As part of the prestigious H-Series, these bearings are specifically designed for engines that see high RPMs, extreme boost levels, and the punishing loads of drag racing or heavy sled pulling.
Unlike standard replacement bearings, the H-Series features a high-crush design and a medium-level eccentricity to ensure maximum protection and oil film consistency when the crankshaft is under extreme stress.
H-Series Performance Casting: Developed for circle track and drag racing, these bearings feature a hardened steel backing for superior support and a cast copper-lead intermediate layer.
Large Chamfers for Performance Cranks: Designed with extra clearance on the edges to accommodate large-radius fillets on high-performance aftermarket or modified crankshafts.
Narrowed Design: Often slightly narrower than standard bearings to provide additional clearance for crank fillets without sacrificing load-carrying surface area.
No Flash Plating: Unlike P-Series bearings, the H-Series does not have a tin flash plating. This allows for a more direct bond and better heat transfer, though it gives the bearings a unique "dull" appearance.
Extreme Fatigue Resistance: The Tri-Metal TM-77 construction is pushed to its limit here, offering the highest level of protection against "wiping" or bearing fatigue under massive cylinder pressures.

Choose the H-Series (MS-2269H) if you are building a competition engine, using an aftermarket crankshaft with large fillets, or running very high RPMs where bearing "crush" is critical.
Choose the P-Series (MS-2269P) for street/strip builds, heavy-duty towing, and general high-performance rebuilds where standard crank fillets are used.
Builder's Note: H-Series bearings are intended for use with high-quality oils and frequent maintenance intervals. Always verify your oil clearances with a micrometer; for most 6.4L performance builds, a clearance of 0.0025" to 0.0030" is preferred for the mains.
