NP231 swap to Dana 300 question???

I would like to know what else do I need to do or what other parts I need to get to swap ND231 to Dana 300 on 90 Jeep Wrangler. I have the correct front axle. What about the shifting lever for Dana 300 would it bolt on the existing lever or what?

Re: NP231 swap to Dana 300 question???

there are kits out there to mount the dana 300 upside down so you can keep the drivers side offset front axle. depending on what engine you got the splines on the output shaft of the transmission will be different. i'm pretty sure the shift levers aren't interchangable. look for a twin stick conversion kit for the 300.

why are you doing this conversion? it might be cheaper just to throw a set of 4-1 gears and a SYE and you'd have a tcase comparable in strength to the dana 300, rather than swapping the case and the front axle.

I'm putting a Wagoneer front axle. The axle is ready.

I'm doing this conversion I think Dana 300 is much stronger xfercase than NP231.

Re: NP231 swap to Dana 300 question???

Dont underrate the NP231 just because its chain drive. 94-2001 Ram 1500 4x4s, mine included have the NP231HD. ITs essentially the same, with a 1.5" wide chain as opposed to a 1" chain in the NP231J, Jeep version. I have (accidentally) driven on dry asphalt with my 6000 pound, 360 powered, 32" BFG wearing Ram and have NEVER had a problem with it...nor do I know anyone who has had trouble with it...But I guess swapping it to get a passenger side drop is ok....hehehe

Correct me if I'm wrong, I have not a change to measuring both xfercase. But I think Dana 300 is shorter than NP231J which is a good swap if you need more room for the drive shaft.

I would say they are roughly similar in length, it you do the SYE on the 231....

Re: NP231 swap to Dana 300 question???

Who makes transfer case clocking hardware? I currently have a 87YJ and am replacing the NP207 or 208 (I forgot) to a dana300 from my rusted 83CJ7. And we all know the diff is on the drivers side on YJ as opposed to the CJ.
So who knows where to get it?

It can be found at <a target="_blank" href=http://www.downeastoffroad.com>www.downeastoffroad.com</a>. You should gain about 6" of driveshaft length with the swap over the NP231.

Goto ebay( www.ebay.com) that's where I got mine I won the bid for $115.00 + $10.00 shipping. Buying from Xtreme about $140 + shipping.
That saves me $25.00.
