A 6.4 crank ground 0.25 mm under on the mains cannot use the standard MS-2269P. This is the P-series set at 0.25 mm undersize.

• Series: P-series is the Clevite tri-metal bearing, steel-backed with a copper-lead overlay, and it is the replacement shell rather than the H-series piece.
• Size: 0.25 mm undersize, for a journal ground 0.25 mm under standard (about 0.010 inch). A standard journal will be too tight.
• Part number: Clevite MS-2269P-.25MM.
• Fitment: 6.4 Power Stroke, 2008-2010.
• Does not fit: A standard 6.4 crank, a 0.50 mm or 0.75 mm grind, or any 6.0 main set.
• Not in the box: Rod bearings, pistons, and rings are not in this set. Order thrust washers separately if the engine needs them.
