New JK build: Dynatracs, Currie Rock Jocks or G2s?

I have a new 2013 JK Sport with a standard transmission. I am looking into replacing the front Dana 30 with either:
-Dynatrac
-Currie Rock Jock
-or perhaps the G2 Dana 44

Any suggestions as far as what is best?
Thanks

pretty happy with my Dynatrac Prorock 44 Unlimited HD

Friend had a problem with a early model of prorock and dynatrac actually warrantied it after the 1 year period was already up. Made my decision very easy which axle I was going to buy.

Either Dynatrac or Currie.

What size tire you looking at running? What kind of wheeling do you do?

Dynatrac would be the best and the most expensive. Not sure why you are doing the swap, are you looking at a 44, 60, or 9 inch?
What size tires?

If you learned something new today, you had a good day.

Don't think G2 makes a JK D44 unless they have done so recently. Another option is the Teraflex 44. Posted an interesting thread about tube strength, I should add the RockJock to the list:

I went with the Dynatrac PR44U. It is much stronger than the stock axle, works great with RCV's and Reid Knuckles with either a Rubicon e-locker, an ARB, or something else of your choosing. The added benefit is the extra built-in caster to keep your pinion angle in good alignment with the front driveshaft for reduced vibration and still keep your lifted Jeep's steering caster at or better than stock so it doesn't feel twitchy while driving down the road.

You can run a large tire on this axle with no fear of bending the inner C's because they are larger than a standard Dana 60 and almost as large as the ProRock 60. The PR44U axle tubes are also almost the same strength as the Dynatrac ProRock 60 axle tubes. They are the same 1/2" wall thickness and there is only a 1/8" difference in the outer diameter between them. Also, with the axle wall thickness being 1/2", it has the same inner diameter as the stock axle so you can use stock Mopar inner axle seals.

Dynatrac is more expensive than the others, but IMO it is the best product out there and it is made in the U.S.A.

I am doing 37"s and probably the most extreme wheeling I do would be something like Holcomb Creek in Big Bear (nice boulder-crawling), or the Escalator on Hell's Revenge in Moab.
Thanks for your help!

I am looking to get 37's. I would like a beefier axle than the 30. I do some moderate to difficult wheeling.

I can agree with this, I can pretty much drive my JK on 35s and only need to hold 2 fingers on the wheel, the extra caster is a huge help.

Another viable option is to find a JK rubi takeoff

^^^ Still should *technically* and *ideally* sleeve and gusset a Rubi 44 with 37's. Same tube size and inner "C"s as the D30 = prone to bendy, bendy. However, if the price is right and you have a welder handy...

I'm running a dynatrac prorock 44 up front and a g2 built currie rock jock 30 dana 60 out back. Very happy with both axles, definitely a big step up form the factory crap.

2008 JK X 2-door, 37" MTRK's, Xenon narrows, 3" Synergy frankenlift, Prorock 44 front with 5.13's/rcv's/rubi locker, Rock Jock 60 rear w/ 5.13's and a Detroit, and lots of armor...

Prone to bending is a understatement, after about 4 months of running 35s on 4.5BS rims I had already bent mine so bad the camber was out of spec.

Another option would be from Solid. We have a pair of D60's on order with them for a great friend of ours and they are shapping up to be great!

The PR44 is a favorite of mine and many others.

I was also going to mention the Tera44 from TeraFlex but it was already mentioned. I think these should get more attention than they do!
