Main journals cut 0.50 mm undersize on a 6.4 need the thicker set. Clevite MS-2269P-.50MM is the P-series set for that grind.

• 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: 0.50 mm undersize, for a journal ground 0.50 mm under standard (about 0.020 inch). A standard journal will be too tight.
• Part number: Clevite MS-2269P-.50MM.
• Fitment: 6.4 Power Stroke, 2008-2010.
• Does not fit: A standard crank, a 0.25 mm grind, a 0.75 mm grind, or a 6.0.
• Not in the box: Rod bearings, pistons, and rings are not in this set. Order thrust washers separately if the engine needs them.
