I have searched here for a couple hours and can not find a thread on this. I know it is a popular swap but can't find good info on the swap.
I have found bits and pieces only.
Here is what I'm gonna do.
I am getting JK HP30 front and 44 rear. The front has chromoly shafts and the rear has a Yukon locker and both are geared 5.13. I am also getting all brake parts, steering linkages, 5 wheels the same size as my 35"s, and Drive shafts to rebuild.
My plan so far is to use Artec truss swap kits for both. I would like to center the spring perches instead off offset to the front to get a 2" stretch out of the front. I will also sleeve the front axle While i am at it.
I would like to see some good builds of this if someone can steer me to the right page.

I have searched for jk to tj axle swap with lots of different configurations with no luck

Thanks in advance...

Not to hamper your plans......I considered doing this JK 44s, but when considering all angles I just determined it wasn't worth it, there are better things you can do for less money. Especially if your doing a front JK Dana 30...that is hardly an upgrade when you look at the strength of the gears which is where they fail. I chipped a few teeth off of a JK Dana 30 ring from backing up in the snow in a parking lot with 35s.

I think if you're going to do it, you might as well throw on tons instead. Going to be the same out of work (fabrication). Brackets, sleeves, shock mounts, perches, coils....you get the idea...

Swap

I'm doing the same swap right now. I got my hands on JK HP30 with RCV and C gusset and sleeves installed and D44 rear both locked with 4.88 gears.

I have RE lift with all adjustable control arms which helps because you do not need to move any of the control arm brackets on the front. The spring perches, sway bar, track bar bracket need to be moved. I am talking my self into the JK2TJ artec kit.

Thinking about doing the artec kit for the rear as well. I still have a lot of work to get the project completed, my self did not come with rear brakes so between that and new drag link, Front track bar hoping to have it completed by April.

i'm gonna take this on with JK Rubi axles front and rear.
most is straight forward , brackets, driveshafts, pinion flanges. gonna get tricky with steering and track bar. sit and think it out. are you gonna change any suspension, 3 or 4 links? do I want to outboard my rear shocks with my new width?

No I did not outboard my rear shocks. I did Fab my own track bar and all steering.
On a note for the front. The instructions tell you to put like 6 deg. (dont remember the exact number) of negative on the shock / spring mounts as I did but after you adjust your caster to specs the shock mounts are angled a little too much along with the spring perches. probably would have worked better flat or parallel to the truss but at least half. This is one area you may want to tack it then check it set up before you burn it in.
