Wiped 6.4 mains knock low in the block and open up oil clearance. Clevite MS-2269P is the P-series main set for a standard 6.4 crank. Do not install it on a 6.0.

• 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: Standard size, for a main journal that has not been ground undersize. An undersize journal will be too loose on this shell.
• Part number: Clevite MS-2269P.
• Fitment: 6.4 Power Stroke, 2008-2010.
• Does not fit: A 6.0 Power Stroke. Use MS-2223P there, even if a cross-reference shows 3C3Z main numbers or MS2223P on this 6.4 set. Not a 6.7.
• Not in the box: Rod bearings, pistons, and rings are not in this set. Order thrust washers separately if the engine needs them.

Order today to secure your replacement. Measure the crank journal and confirm standard versus undersize before you install it.
