Hello all,
This applies to 6 speed owners 05-07 models. I know it is a pain to have to crawl on your backs to get under your vehicle, if you wouldn't mind crawling under there and posting what the tag says on your transfer case.
Mine says 241 J. I was wondering if yours says that as well, or if it says 231.
I appreciate it....have a good weekend.

the 241 came with all six speed manuals. for 05 and 06 and 07. the 231 was mated to the auto and i belive the old 5 speed.
the 241 is a 1/2 and 3/4 ton truck transfer case used in dodges and some fords and is alot stronger than the231.
and it is not the same 4-1 case in the rubicon. it shares alot of charactersitic of the rubicon case but has different internals. mike

I crawled under my 2006 with the NSG370 6-speed and I have an NV241.

Like Jason said yall, carry over from another thread...Jaws of Death and hoopersfish proved themselves wrong, they DONT have a NV241 like they claim

Brian & every one else
I dont want this to sound like a pissing contest
but fact is KJ's have NP cases in them

nv (new venture) and np (new process) are the same manufacture. the only difference is the wall street name change after the wall street merger. but as for the hd i don't know the difference between the hd case and the regular. but i invite you over to my place i really do have a 241 under my kj and it came from the factory. it is my understanding that the 242 is a full time case. i do not have fulltime. i have the command track system (part time) and the tag on my case says 241. also i have the 231 case on 2 other vehicles and the 231 case is significantly smaller than the 241 under my kj.mike

Yes NV and NP are the same company BUT there is a big difference between sayin you have an NV241 (4:1 ratio, only in Rubicons) and a NP241J (2.72:1 ratio, which some of yall got in the 6spd KJs).

already i just read the whole post and i wish i could take a picture and post it. but i am computer illiterate in posting pictures. so the invitation is on anybody close to cincinnati, you have an invite to come over and take a picture to put this to rest. just pm me!

ok just climbed under it it says 241J nothing else but the serial # and the model #.

it does not give a designation of nv or np in front of it. mike

See were it says New Process....hence the NP, like Brian stated.
