The front d30 is not good to 37" tires, especially when pushed by v8 power. The d30 is only marginal with 33" and 35" tires and a stock motor. Anything else is asking for trouble. I think you would do just fine with d44's.

Doesn't make it right, or smart. Could be 1000hp and 52" tires, either way it's a ticking time bomb. Using minuscule axles with high horsepower and the leverage of large tires is a recipe for disaster and it's not a good idea to recommend it just because somebody has limped it along or been lucky.

In all seriousness if your gunna do it. Spend a few extra bucks and if you do go for a 44s. Make sure you are not going bigger than 35s. Front may be ok going bigger but rear would hate life. Which is why i say the nine inch. The will live to 1000 hp and huge tires and there is more after market support than any diff out there.

i am the one witht he 383 and the amc 20 with the dana 30 up front i agree with bounty hunter i have been very lucky with my axles sofar but i am running them till they blow apart and then i am moveing up to a min of a dana 60 but yet in my def. a amc 20 built up as i have done mine is still just as stronge if not stronger then a d44 for one it has a larger ring and pinion but i built my jeep on a budget and when i first built the axles i wasnt planing on running the big motor originally it was going ta be the stock 4 banger in it but circumstances changed when my motor blew a rod and i had the stroker sitting her waiting ta go into my camaro witch got totaled hence it ended up in the jeep so if i had ta do it all over i would start out with the dana 60's front and rear with chrmo shafts and lockers
Thanks for all the insight guys, I wish that I could go with the 60's but they are out of my price range for now. So the 44's it is, for use as a daily driver what gear ratio do you think that i should go with, I want it to be good for a daily driver but still do what I need it to off road. Also I'm looking to do a Full Traction Suspension 6" Long Arm Suspension System with M-Force Monotube Gas Shocks, thoughts or better suggestions?
D44 front, I would go with a 9" rear. probably cost the same to build as a D44 rear, but with higher horse power, you'll really appreciate the added pinon snout bearing on the 9"
and FYI, I've blow apart D44 chromo shafts with a bone stock motor, motor was just off idle, tire was severly wedged between rocks and could not see it.

Let me know if I can help with any of this. I sell both Full traction and other suspension product as well as axles from Dynatrac, and Currie. I would go with the 4.56s for 35s and 4.88s for 37s (depending on trans). Did I miss what trans you have?

With the V8 power you are adding and running 35" tires, D44s on both ends would be minimum I would recommend.
Even better would be to upgrade to a D60 in the rear and either a D50 or D60 in the front. If you tend to have a heavy right foot, go D60s on both ends.
As for the gear ratio, 4:88s would put your STOCK (with the 4.0L) RPM back into balance. Without knowing more about your engine swap, I don't have enough info to make a "sure" change.
It would also help to know what you plan to do with this rig... (Highway; Hwy/trail; trail only; extreme)
With the additional weight you are adding, will you be adding heavier front springs? Is the Jeep lifted... how much... long-arm or short-arm? All very important to make a proper recommendation.
