Question JK Axle upgrad For a TJ

What woud be the disadvantage to running JK D44's under a TJ? I know they are wider, but could you get wheels offset enough to get close to a TJ's width? You would also have to install new brackets for arms, springs and shocks.
They are only $1400.00 a peice. Seems like a good deal.

Thats for Locked Rubicon axles too.

do it the locker is an easy hook up all you have is a ground and a positive
the only disadvantage is that you have to cut off the brackets and weld on some new ones and the rim bolt up pattern is different but you can either get new rims or there is some adapters you can get

as for the width they are only 2.5" wider per side

the JK D44 is stronger than the TJ D44

If I had the money I would do it the JK D44 should hold up to 37's no problem
or you can put some alloys in and run 38's-39's

the ring gear is thicker and I remember reading some where that the ring gear is a little bigger
the pinion is beefy compared to the TJ D44 the JK D44 is closer to thickness as a D60

there was an article about the axle in one of the 4wheeler magazines

Pretty sure the locker isn't that easy. It pulses at a really weird rate. Now I haven't been paying any attention to it on the boards, but unless someone has come up with a way to match the pulse going to that locker I don't think it will work.

Otherwise ripping off the brackets and doing TJ stuff wouldn't be too bad. But hell if you are doing that and getting new wheels or spacers to boot why not go for 60's or 60/44 combo? You are going to spend at least 4-6k on that project anyway.

I read that petersons and was thinking the same thing. I thought it said that it was just a 2 wire hookup as well. Sounds to me like it wouldn't any more work than an 8.8 swap except for the bolt pattern and you would be locked.

Here's another option for a rear d44. I was looking at Nissan trucks and found this
Drivetrain from the Frontier model
Dana® 44 rear axle (M/T only on SE V6 models)

I couldn't find what gears are in them though. just a thought

The Frontier D44 is much like the one in the Titan as far as I know, and those have been nothing but trouble for the guys that have lifted them.
