rear main seal

[dangerous06]

Why are there so many choices on the seal part Number? Which one is best?
Seems the cranks are all the same till 12 or 13?? Is one better than the rest?

I buy from Cummins. Whatever they are, that's just my preference.

I used a FelPro in my last truck. Lasted 18 months and 30k miles before I sold it.

i always use Cummins seals. seen too many nationals, and fel pros fall apart and leak to trust them. may have been installer error though. that's all up for assumption. i just feel better about using the Cummins seals. seem to be a better designed seal.

I agree with stubz616, OEM Cummins!
