FAQ
Is this the correct size for my engine?
This listing is for STD (standard) journal size. If your crankshaft has been ground, you will need the matching undersize bearings—confirm by measurement.
How many do I need for a full set?
The 5.9L Cummins uses six connecting rods, so a complete engine typically requires six pairs (one pair per rod).
Does this include main bearings or thrust washers?
No—those are sold separately. See the Related Parts section for common add-ons during a rebuild.
