Is the US made seal better than the other neoprene seal (800093)? Other than the price they look to be designed a little differently. Is one of the two better at preventing leaking? Thanks

Willys Jeep Parts Tech:
Alot of people prefer US made seals when available.

What is difference between 80093 and 800093k

Willys Jeep Parts Tech:
I dont see the one part number your referring to.

Does this seal fit correctly? 800093 is too tight on the crankshafts, a well documented issue it seems.

Willys Jeep Parts Tech:
Both our seals fit correctly. There are a few manufactures that they are tight. But we dont sell those.

Is there a simple picture showing the proper install

Willys Jeep Parts Tech:
Email mike@kaiserwillys.com and I can send you over an image.

Which way does the main seal go in. There is a flat side and one side with what may be referenced as a lip.
