(TJ) Front axle upgrade, good idea??

This summer I was thinking about putting in some Superior axle shafts for the front and a hub conversion. Eventually I plan on going bigger with my tires (who doesnt) and at least an 8.8 rear for my TJ. (4.56's too)
Does superior make the best (at least good) front axle shafts?
Where is the best place to go for the hub conversion or company?
I plan on running at least 35's and at most 37's some day.
any info would be great, thanks

If you havnt tried a search I would suggest it. Most people on this board are not running "stock" axles. Go with WARN. you might want to think about a dana 60.

i tried doing a search, but maybe i didnt type in the right key words.
Ya, i was thinking superior on the axle shafts and warn for the hub conversion, maybe even a locker too.
i dont know i if i could afford the 60 right now, but i guess i would have to see...
i would want to go full width if i got a 60.

If it was me, Id go with an 8.8 rear, and a 44 up front. You could get both of those done fairly cheap.

1badPOS Is right!

My 97 TJ has had a dana 30 up front since new and 35's. I have only broken like 12 or 14 U joints and 4 axles and like 3 ARB units so far....

and AS for the rear, My stock dana 35 c has only broken like 12 ARB units so far, but no axles!

So my suggestion is this, Spend money one time, Go big and get it done right.

LEARN FROM MY Misfortune.

Thanks for the replies everyone!
I will do a search to see what axles I should go with, unless some one wants to make a suggestion of what axle i should go with up front...
And for the rear i was thinking out of a newer for explorer for that 8.8
thanks again

not to be judgemental, but by reading into your replys and post it sounds as if you would be quite happy w/ a D44 up front...

Purdue:
your thoughts on axles are good. Superior Axle up front and an explorer 8.8 in the rear. As for Airpups "Go with Warns". He obviously is a follower. Superiors new 4340 chrome moly axles are made much different than warns and this is what makes them better.
- they are both forged from 4340 chrome moly. this is the only similarity.
-warn machines theirs, hobs(cuts)splines, and sends them out for are 55 rc through hardening. this makes there shafts very rigid as many know. rigid isn't good as it puts added stress and load on all other components. and this is also why their holes are oblong most of the time as they warp during heat treat.
-superior sends theirs out for a mild through hardness 40 rc BEFORE machining. then they mill the ears(so they don't warp) and machine the body. they torsionally align both the short shaft and long shaft so that they react the same(in simple terms they change the diameters of short shafts so it react the same as the long shaft after induction hardening ). they then ROLL spline (cold forming) and then induction harden the shaft. the induction hardening is what allows these shafts to absorb load and make all other components, includung the axles, last longer. induction hardening is a process that puts a thick case hardening on the shaft and in away makes the shaft able to perform more like a torsion bar. They achieve a 57 rc hardness on the surface and as you go into the shaft it gets softer and softer(57rc, 55, 53, 50 etc) until you get to 24% of the diameter on either side and then you get to the 40 rc from the through hardness and it stay consistent to the core.

as for airpup i'll quote Goat1: "those of you who think you know everything really annoy those of us who do"

good info TJmike. I actually run inner Warns and outter Superior w/ CTM's in the middle. I might not had gone Warn if I had known the info you posted.


EDIT: Superior's were not out when I upgraded the inners.

thanks for the advice everyone, it is really hard on what i should do because i am a newbie to the axle swap thinking. i am trying to find some articles or some thread that help me understand all the "lingo". if anyone knows of any good articles, that would be great.
thanks

The Superior shafts are cut for the TJ factory unit bearings...keep that in mind, you'll have the outers left over when you do the Warn hublock conversion. Besides, the Superior shafts (set) costs almost as much as the Warn conversion.

For the price of warn shafts and the hub conversion you could have a nice 44 up front. Go full width and get a 14 bolt rear.

Or if you have the $$ just go 60 fullwidth and some 38s.

Don't bother upgrading the stock shit it sucks balls.

I have a question.. are you breaking parts now?
If not, then why upgrade to stronger shafts?
