A Duramax rod bearing that wiped needs the pair that matches that rod, not the other standard number. Clevite CB-1990P is one P-series pair. Its published shaft diameter matches CB-1805P, so the part number is the difference, not the journal size.

• 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 rod journal that has not been ground undersize. An undersize journal will be too loose on this shell. Spec material is VP-3. Shaft diameter is the same 2.4764 to 2.4772 inch as CB-1805P.
• Part number: Clevite CB-1990P.
• Fitment: LB7, LLY, LBZ, LMM, and LML Duramax, 2001-2016.
• Does not fit: CB-1805P until you confirm the rod, CB-1805H, a 0.25 mm grind, or a 2017-up L5P.
• Not in the box: The other rod journals are not in the box. Mains, rings, and a piston are not included.
