A standard 6.4 rod journal that runs tight can wipe the overlay without ever being ground. Clevite CB-1869HX is one H-series pair with 0.001 inch of extra oil clearance. An undersize crank is a different part.

• Series: H-series is the Clevite tri-metal performance bearing, with medium eccentricity, high crush, and a thin overlay, so the shell stays seated and clears a larger fillet. The X on this number is Clevite's 0.001 inch of extra oil clearance on a standard-size journal. It is not a bearing for a crank that has been ground undersize.
• Size: Standard journal only, 0.001 inch more clearance than CB-1869H.
• Part number: Clevite CB-1869HX.
• Fitment: 6.4 Power Stroke, 2008-2010.
• Does not fit: A journal ground undersize, the P-series CB-1869P, or a 6.0 or 6.7.
• Not in the box: The other rod journals are not in the box. Mains, rings, and a piston are not included.
