Dana 44 vs Dana 30 axle (picture)

Just in case you are a noobie like me and were wondering what the Dana 44 vs the Dana 30 stock axles look like in comparison I figured I would throw this up here since I found it while browsing and researching.

FYI the way I understand it JK comes with the Dana 44 stock in the rear and the Dana 30 stock in the front. Anyways I found this picture to be an excellent example and figured I would share:

I will also throw this link up here as well as it has a general rundown of the stock axles and also some information on how to strengthen your stock axles in a cost efficient way (in-case anyone is interested and trying to research like I am):

the ring gear and pinon may be bigger but both the D44 and D30 have the same Achilles heal, weak ass hell ears on the axle shafts and the same u-joints

+1 I watched a guy snap the top ear completely off on the front drivers side on his on his TJ a few months ago.

What are the other better options for gears and manufacturers that are better quality. I am wanting to upgrade to 4.56 gearing's and want to upgrade my Dana 30 front to Dana 44 or better since I'm going all out to make it completely right. I do moderate trail riding and want it more robust for long weekend camping and short expedition trips. I'm putting in a 2.5" Teraflex lift and want the gearing best suited for 35"s.

What are the benefits of the Dana 44 Axle compared to the 30 Axle? I'm assuming it's better for off-roading?

Just remember the pinion size changes with the count of the gear teeth as well, are those pinions from the same vehicle?

Are you talking about when doing serious off roading/rock crawling. Or just in general.

While researching my axle swap I found the tereflex 44 is quite beefy and not a bad price for what you get. If you go with a stock 44 you would want to sleeve and gusset it. I'm no expert it's just what I've learned from here and fellow jeep peeps. Spend the money once and do it right.
