JEGS shows the front for $3800...Rear $1700. Probably available cheaper soon.
Unsure of availability.

I called northridge a few weeks back and they said they had no time frame on when it would be available. Dana direct says its available now. Im very interested in it, seems like a great option and competition to the dynatrac.

I'd be interested in these too at that price point. I can't find anything on the rear axle, though...only the front.

I think if you're upgrading from a d30 and you don't have access to the right tools or you don't have fab skills it's a good deal. I was going to go this way, but I found a place near me that's owned by a guy who runs a small time Miata race team who rents out space in his shop for $55 a month, so I'm thinking of building my own now.

Does any one know how much the pinion and caster separation has been increased on this axle?

Their description states "Pinion angle optimized for lifting vehicles" and "Improved caster angle for lifted Jeeps", Would be nice to see some numbers for comparison.

We may be the only Dana Spicer service center that actually has these in stock? We ordered them close to 6 months ago and received them a couple months back.

As per my measurements in the shop, it appears that there is about 2* of pinion angle added to the U44 and 2-3* of caster also added. The brackets look really nice and the first axle we installed went very smooth. Alignment after install came out perfectly in spec and the Jk drives great. Ill try to contact the people that we have sold these axles to and see if they are members of JKOwners...maybe i can get them to post up their reports here.


EDIT*..... Please contact me for pricing on the U44 axle. I think you will all be pleasantly surprised

FYI.... there are only front axles available right now. I don't believe there is going to be a bolt-in rear U44 option. I know there are some generic 44 rear axles available from Dana. We use some of them for base axles in Industrial applications.


There are also front 44 crate axles that are U44 axles minus link brackets. They still have the cast-in upper link mount on the diff but nothing else. They also come complete with JK knuckles and unit bearings. Just missing brakes. They have been a great option for builders. We actually use these as a platform for other vehicles. Feel free to PM me if anyone has questions about any other axles!

So the separation is 8*-10*? Can you get a solid number for me please?

The only angles we are at liberty to discuss is the difference between pinion angle and caster. Individual measurements are proprietary to Dana Spicer. This isn't me being a at all, but the majority of people asking these questions are others from the industry looking to copycat what is being done with these axles. I will get the measurements that I can off of the axles in the shop and report back.

I can say that you can easily achieve the stock caster (and slightly more) with the U44 all the while keeping your pinion angle in the best position necessary. These angles were the average of multiple common lift sizes and arraignments. The brackets have also been moved to take full use of the improved caster and pinion angles. I hope you all understand that my hands are tied on certain proprietary measurements!

I understand... I guess. I didn't ask about anything other than caster and pinion angle.... The difference between caster and pinion would be the separation that I asked about.

I hope that you also understand that this axle will no longer be considered by me because of the lack of information that is available about it (don't expect that PM I mentioned earlier) I hope you also understand that my hands are also tied when it comes to making a payment on something that I can't get basic information about. An improved caster and pinion angle is a big reason why I am looking at after market housings and complete axles. If I can't know the separation of the pinion and caster, I can't consider the axle.






(While I mean what I said, take it with a side of humor. Not being a dick, just find it sorta ridiculous Dana won't provide a basic measurement that they are bragging about in their sales pitch.)

Thanks for helping me narrow down my options.

Are the C's on these actually beefed up?

I totally understand what you are saying. According to the digital angle finder placed on the axle on my bench, the angle separation between the pinion angle and the inner "C" is 9* on the nose. I hope you will reconsider the U44 and would consider getting a hold of us to purchase one! Thanks

EDIT: I hope that the info that I provided gives you some reassurance. We are trying to be the go between for the end user (you) and a very large corporation (Dana Spicer) that has traditionally played their cards very close to their vest. We have been a Spicer service center for almost 40 years and are very used to dealing with their proprietary BS. We work very hard to make sure that the customer gets the most information possible before a purchase because frankly, money doesn't grow on trees!

Yep, thanks for a solid number on the caster and pinion. I wasn't trying to get into proprietary information. What 1 company posts openly, others may keep secret.

9* separation is good for me.

MAYBE slightly but I wouldn't expect to be able to avoid gussets. The tubes and Cs would still need a little beefing up to be safe for hard use or to be close to comparable to Dynatrac, Currie, or Teraflex 44s. 1/16" thicker wall thickness without increasing OD doesn't add a whole lot of strength.

I'm assuming this is a tweaked JK Dana 44 with J8 tubes. JTPhoto built a couple of the Dana 44 HDs and shared his observations comparing the Cs.

I heard RK control arms when greased with the special and so hard to find 000 grease were so bad ass that only Dana 60s can handle their awesomeness..... But then again you know how rumors and fishing stories go.

They are not. In all honesty, 99 out of 100 times when someone says they have a bent C it is actually the tube where the C welds on. The only time I have genuinely seen a bent C is after a serious wreck. Feel free to add C gussets to these axles if it gives you peace of mind. We can even add them to your axle before they ship if it helps you lean toward us a vendor, I just don't think you will ever need them. Just my .02c

Yep that super hard to find stuff that you have to use on Metalcloak Duroflex joints....

Super Lube 21030 Synthetic Grease (NLGI 2)......

Go ahead and do your google search on it......

I'll just leave this here to get you started....

http://www.amazon.com/Super-Lube-210...0XBH9HI/ref=sr


How many stores carry that stuff again?


It's a shame that 000 grease that RK requires isn't as readily available in such small quantities as the grease that's recommended for Metalcloak joints.





Just saying

Does anyone know what ball joints are installed on the ultimate 44 axle? Just was wondering if those are beefed up or the same as stock, as I have not seen or read anything regarding the ball joints on this axle.

Probably just stock/factory/off the shelf ball joints. No mention of any special ball joint and Dana will use off the shelf parts to keep cost down.
