FAQ
Is M-4955522 the correct set for my 2011–2012 6.7L Ram?Yes—M-4955522 corresponds to the Cummins 4955522 lower set used on ISB 6.7 with CM2250 controls, which covers most 2011–2012 pickup applications. Verify by ESN for cab & chassis or edge cases.
What’s the difference vs. the OEM Cummins kit?
Functionally equivalent sealing for the lower end at a value price. If you require an OEM-boxed kit, the Genuine Cummins 4955522 is available separately.
Does this include a rear main seal?
Lower sets typically include the rear crank seal service kit for the application. Check the parts list for your ESN to confirm final contents.
Can I pair this with an upper set?
Yes—pair with the appropriate upper set (e.g., Cummins/Interstate-McBee equivalent of 4955523) when performing full refreshes.
