the dana 30 isnt that bad of an axle, the 35 now thats a different story. i wouldnt go over 5 inches of lift if it was me. makes it to top heavy. i would just get out the grinder and welder and cut out the fender wells and run 37s

My wheeling buddy snaps his D30 with 35's all the time. He even told me when I got mine not to go over 33's with a D30. I saw him turn real sharp to pull into camp one night and snapped his outer axle right there on the main road without even getting to wheel all weekend.

I would go atleast 8.8's with it and stock to 2.5" springs.

im running the d30/d35 and 37's and still no problems....of course i dont beat on mine like most but for a street/mild mudder i think that the d35 could be upgraded to handle them just fine.....rock crawling is completely different from mudding...it puts extreme stress on the axles. i have a 8.8 ready to go in WHEN/IF the 35 breaks. everyone wants to know how well a 35 will hold up to 37's.....i will keep you posted and as far as the d30 goes im not worried at all

Mudding puts just as much if not more stress on the axles as crawling.

When you are spinning your tires in the mud to keep them clean and hit some traction = KABANG!

It's common knowledge that 35's are about the limit for a stock (open) D30. Chromoly shafts will buy you a little bit of insurance but not much and IMO you would be better off spending the money on a D44 rather than polishing a turd.

Yeah thats it, dump a ton of money into a D44 and then, o wait, it has the same size u-joints as a D30. DOH!

If your gonna dump money into a new front axle, Polish the 30 up a bit, then save your money and do a 60. Skip right over the 44 if your 30 isnt strong enough. Truss/Gusset the 30 housing, throw a full carrier locker in it and some chromo shafts with a GOOD set of ujoints and you'll be just as/if not stronger then a stock 44 that you'd have to dump money into to get it into your rig.

Yeah, put an $$$ expensive, low hanging, 600+ lb 1 ton full width axle under your rig because it's stronger than a D44 and have your tires stick out so far that you can no longer drive it on the street (legally).

D60's are much harder to find and will empty your wallet real quick.

The D44 is a good compromise between ease of installation, cost, weight, clearance and strength (when built properly).

why does huge SOA turn into such an ordeal. This fight already happened in Highrollcustoms thread. holy **** just answer the guys question. hes not asking if its to tall to get his vag into it. he wants to go big. nothin wrong with that. to do it right you will need (and it will cost you alot) and probly some stuff i'm missing...
-Bigger Axles (D60's, maybe a 14 bolt). you will need to rebuild them "lug-to-lug". and Iron maiden the tires dont have to be illegal. someone decided to invent backspacing a while ago to adjust for that. ever heard or fender flares either? hmm guess not my bad
-Super short SYE (probly JB conversions) and a tom woods DS. its gonna be a steep DS angle no matter how you figure. You'll need a MML at least 1"
-Wheels for your new 8 Lugs (make sure you have the right backspacing so everyone doesnt get mad at you )
-Tires are gonna cost you a ton. especially on 16 or 17 inch rims
-JB 4x4 high steer knuckle and drag link, and a beefed tie rod
-Gears for the axles and them installed
-i'm probly forgetting a lot but thats a list to start with.... next time if you dont have an answer to the question, just press the back button and look at other threads

Thank you, agreed. I'd never consider a D60 for my 35's or even 37's. For now my ARB and X297/X760 u-joints are doing fine. Should I need to deal with a front axle, I'll probably sell the D30 ARB and do a D44.

x2 this thread got way off track.

OP, I've got 4in rough country springs and I'm going to try them soa, but I imagine it will be too tall for me running 36" tires. I won't know till I try though, and I would recommend you do the same and see if you like it. If you don't then just get new springs or put the stock ones back on, simple as that.

Steering... you need some sort of high or crossover steering setup. Do a search and you'll find a lot on that subject.

He wanted to know what he was in for with his plan. That obviously includes what is needed technically, which is how you see it.

Since a ride that tall is on the more extreme end of lifting a Jeep and the OP gave no indication of why he chose to do that other than he already had the springs, offering concern is appropriate. He also never came back in subsequent replies to indicate he was already aware of the concerns. TMI is better than rolling over.

True, more information is always better, but I see these arguments about axle strength come up all the time, even when they're uncalled for.

mml means motor mount lift. It's to help with driveline vibrations mostly. You will want to look into anti-wrap perches and definitely address the steering. High steer and crossover are really the only two options.
