I'm currently running the same thing. That's why I want to find a D44 with 4.10's. One day I hope to run 35's but that's farther down the road

If you get a 4.10 rear axle ratio, you will need to have the front axle re-geared to 4.10 before you can safely engage (or utilize) 4WD.
Awesome. Got it now. Thanks!

apannone Ok got it. So if I have a wrangler with a d30 and d35 with 3.07s, the d30 is geared differently in my jeep than a jeep with a d30 and d44 with 4.10 gears. Is that right? Just want to make sure I understand.
08-26-2013 07:16 AM
Jaxon1023 If you ever want to use 4wd yes you will have to regear. If you just put the 44 in and don't regear it will get you down the road till you can afford to regear the front as long as you keep it in 2wd

But you can do a Dynatrac Hp D44.....its also a direct swap but the axle itself is a few grand.....but its a nice axle for sure.
Just a hypothetical question as I have no intentions of doing this swap; I run 31x10.5R15... I just always thought it would be nice to have matching D44's. Thats why I asked...

How long before you found it?

There's a few jeep only junkyards lying around... But your best bet will probably be buyin one off of some random guy parting a jeep out!
Yea I figured I won't have any luck but I guess it doesn't hurt to check. I'm just going to have to be patient while searching for one

Definitely not 100% true or accurate. D44's have quite a lot of advantages, including ground clearance, aftermarket support, ease of swap in, and when built up strength(check out the strength ratings when using 33 splines) is right there as well.
08-25-2013 12:29 PM
Teague242 That's alot of money when you figure you can spend another grand and buy a superior or G2 rear that's already built and locked....

I'd go with finding a used one. It might take a little but is rather spend $600 than 1200 on getting my jeep mobile again.

Notoriously_rob Yea i was just reading it online- apparently i want to make sure i get an iron vice aluminum case...didnt know tjs came like that--more readin for me

Jerry Bransford Spicer = Dana Spicer which is who made our TJ axles & drivetrain.
08-25-2013 12:18 PM
Notoriously_rob So this is telling me a spicer 44 is available...for $1200...

Is spicer the same as dana 44

Not very knowledgeable on differentials..

Not to mention the 8.8 is offset a different amount compared to the transfer case so you have a compound angle at the rear driveshaft u-joints that isn't present with the D44. Not often a problem but... and if I want significantly stronger axleshafts than the 8.8 comes with, going with alloys like are in mine is easily done... and there are even 33 spline and 35 spline shafts made for the D44.
I'm the same way, much rather have a Dana 44. Mainly because I'm only 19 and not that mechanically wise yet. So since my dad will be guiding me to put it in, I don't want to have to weld on all kinds of new brackets for an 8.8. I have the money saved up and have always wanted a Dana 44 ever since I've had my jeep

mang318 Awesome. Thanks guys! I can't wait to find one and get it in my jeep

jsuggs You can try this place. I have bought a lot of parts from them over the years. As with any salvage/used parts do not be scared to negotiate the price.

TJDave Found my built Rubi D44 on a Jeep club website that is in my state. The previous owner was swapping in a RJ 60 in to his Jeep.
