Cummins mains that run tight on a standard crank wipe the overlay even when the journals were never cut. Clevite MS-2328HX is the H-series main set with 0.001 inch of extra oil clearance. It is not an undersize set.

• 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 journals, 0.001 inch more oil clearance than MS-2328H.
• Part number: Clevite MS-2328HX.
• Fitment: 5.9 and 6.7 Cummins, 1989-2024.
• Does not fit: A crank ground 0.25 mm, 0.50 mm, 0.75 mm, or the .026MM size. Not the 4BT set MS-1718P.
• Not in the box: Rod bearings, pistons, and rings are not in this set. Order thrust washers separately if the engine needs them.
