FAQ

Will this fit both 12V (6BT) and 24V (ISB) 5.9L engines?
Yes—this bearing is listed for B/ISB applications covering 1989–2002 Dodge Ram 5.9L. Always confirm by ESN due to mid-year updates.
How many do I need for a complete engine?
You’ll need 12 halves (6 pairs) to service all connecting rods on a 6-cylinder Cummins 5.9L.
Is M-3969562 an upper or lower shell?
Some rods use unique upper/lower shells. M-3969562 crosses multiple OEM numbers; pair per ESN and rod style. If your application specifies a dedicated lower shell, use the matching part per Cummins data.
What if my crank is ground undersize?
You’ll need undersize bearings (e.g., .010", .020", .030"). This listing is Standard (STD) only.
Does this fit 2003+ common-rail (CR) engines?
Common-rail engines (’03+) often use cracked-cap rods and different shell pairings. See the appropriate CR-era part numbers for those applications.
