Modify JK Sahara
Hi Guys!
As a newcomer to this forum, I'd like to get your input regarding my upcoming transformation of a JK Sahara, 2-dr.
1. I'm running on Dana44 HD rear, and Dana30 HD front and plan to add 37" wheels, anything to think about? There will be no extreme rock climbing, mostly forest, moderate climbing and mud... I'd prefer not to swap axle assemblies, but perhaps stronger axles would be in place, or?
2 . In addition, I'm planning to add ARB Air Lockers front + rear - would they affect any of the new onboard systems?
3. The electronic swaybar disconnect for the Rubicon model - what about it when you add a 4" suspension kit? Anything needs modification, or does it work anyway?
4. When adding Bushwacker fender flares, what would be the ultimate backspacing when running on 37x13,5x18" wheels? I'd like the tires to stay within the flares, due to Swedish law...
5. Guess a change of cv-shafts would be essential, huh?
6. Teraflex 4" - these seems best to me, with exception of Rubicon Express 4,5" longarmsystem - what do you think?
7. Any other tips highly appreciated!
Best regards, David

Your best bet with 37s for the trails you describe would be to upgrade axle shafts in the D30 when you can. I wouldn't see need for complete assembly swap if it were me.
With the Rubi sway bars, I believe everyone just adds longer end links and the disconnect works same as always. You can search the forum for people who have had problems with their sway bar links "inverting" with the end link joint moving forward during travel and hitting steering components.
That is the exception, however.
I haven't researched 4" kits extensively since I only went with BB for now, but RE and Tera would be at the top of my( and most I think?) list. Currie Ent came out with a new kit as well that I'm sure is quality. Full Traction is popular here and you can find lots of info on the forum search about them.
I think most are using 4.5 inch backspacing for 12.5 tires, haven't looked at what those with 13.5s are using.
Not sure if longer driveshafts are required with 4" lift or not, but I would if it were even recommended not required.
OK, so why not go with 35s and a 3" lift for your intended use? I can't imagine too many places you couldn't go with 35s and ARBs.

Thanks, appreciate your answer!
Yep, I had ARB front/rear on my TJ as well, and want to maintain the feeling of having it when you need it. However, the JK has some built-in systems, ESP, ERM and so on - hence my question. But, I guess you're right, it should work anyway.
The 35" suggestion has also crossed my mind, the only reason for getting those 37" is looks...
4" lift together with 37" wheels just looks sooo good! And, I might add, it gives better ground clearance as well. But to go with sence, 35" would probably give better onroad performance... choices, always these choices!
