FAQ
Is M-4892795 the lower shell only?Yes. It’s the lower shell. For a .010" undersize pair, use upper 3901171 with lower 4892795.
How many do I need for a complete engine?
Six rod journals = 6 lowers + 6 uppers. Order per journal and per size.
Will this fit 5.9L and 6.7L Cummins?
Yes—03–07 5.9L ISB and 07.5–18 6.7L ISB that use fracture-split rods. Verify by ESN.
What if my crank is standard size?
Use standard shells (e.g., lower 4893693 with the matching standard upper) instead of .010" undersize.
Can I mix .010" lowers with standard uppers?
No. Bearing halves must match size (.010" upper with .010" lower) on each journal.
