A common-rail rod journal ground 0.25 mm undersize will wipe the standard CB-1873AP. This is one A-series pair at 0.25 mm. Use it on a 2003-2018 5.9 or 6.7, not the 1989-2002 rod.

• Series: A-series is the Clevite aluminum bi-metal bearing for an OE-style rebuild, not the tri-metal H-series.
• 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 CB-1873AP-.25MM.
• Fitment: Same engine as CB-1873AP: 5.9 and 6.7 Cummins, 2003-2018. OE family is the 3939859 / 4892796 common-rail bearing, not the early 3901170 rod.
• Does not fit: A 1989-2002 5.9, which uses CB-1413P-.25MM. Also not a standard journal, a 0.50 mm grind, or a 0.75 mm grind.
• Not in the box: The other rod journals are not in the box. Mains, rings, and a piston are not included.
