[Weasellee]

Attached is a photo of a 241J for sale (locally). Have you seen the 4-1 stamped 4 2 1 before?

Does the SN beginning with an 8 indicate a 2008 build? Notice that @g.hayduke's begins with an 04.

Mine is an 04 but my serial number starts with 11

Mine is an 04 but my serial number starts with 11

So much for that theory!

421=4:1=4to1
Maybe?

Evil AI tells me this.
Yes, some Jeep Rubicon transfer case ID tags do have "421" stamped on them. For example, the NV241J transfer case, commonly found in Jeep Rubicons, is known for its 4:1 low-range gear ratio, and some tags may display "4-1" or "4 2 1" as part of their identification.

4-1, 4-1, 4 1 (lost the - die)
421, 421 (used the 2 die)

It has the enlarged planetary section. It is 4:1. Whether or not it bolts to a tj transmission is something else.

Look up pics of the jk and jl variants to be sure?

 

[hosejockey61]

Looks to be correct. But at stated, make sure it's not a JK 241. I'd also find it where that leak is coming from.
