FAQ
Does this include the timing cover seal or rear main seal?
No—those two seals are not included in CS54774-1. Add them separately if needed.

Will it fit my 2007.5–2018 Ram with the 6.7L Cummins?
Yes—this set covers 2007.5 through 2018 6.7L Cummins ISB applications as listed above.
Is it OE quality?
Yes—MAHLE gaskets meet or exceed OE specifications for form, fit, and function.
