crankshaft seal from National or Mopar

[carlv12]

Hello,

I want to fit a new crankshaft seal. There are two different brands: the one from National = 710698 and the one from Mopar = 5037300AA. Rockauto offers both. Do you know if there is a real quality difference or maybe National is the manufacturer and sells it to Mopar?

Thank you and best regards from sunny Valencia (Spain)

It wouldn't surprise me if the Mopar seal is just a National. Depending on how quickly you want to get the job done you might be able to pull the old seal and get numbers off of it first to check. A lot of times I'll do that with bearings and seals to find replacements, but it means taking everything apart before ordering new parts, so it makes the job take a little longer.

The National seal is the incorrect part. Use the Mopar part
