FAQ

Will this fit both 5.9L and 6.7L Cummins engines?
Yes—M-4955853 is designed for standard crank journal diameters used across 5.9L and 6.7L Cummins engines in Dodge Rams from 1989 to 2018. :contentReference[oaicite:11]{index=11}
Is this the same as Cummins OEM 4955853?
Yes—this Interstate-McBee part is an aftermarket alternative built to the exact specifications of OEM Cummins 4955853 main bearings.
Do I need undersized bearings?
Use standard—that’s what most rebuilds require unless crank journals have been machined undersize. For oversize needs, see M-4955860 (.010) or M-4955857 (.020). :contentReference[oaicite:12]{index=12}
