A Duramax rod journal ground 0.25 mm undersize will wipe the standard CB-1805P. This is one P-series pair at 0.25 mm. It is not CB-1990P.

• 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 CB-1805P-.25MM.
• Fitment: Duramax, 2001-2016, same years as CB-1805P.
• Does not fit: A standard journal, CB-1990P, or the H-series CB-1805H.
• Not in the box: The other rod journals are not in the box. Mains, rings, and a piston are not included.
