Does anyone have any idea or info on the "Mopar Heavy Duty Rubicon Axle Housing"?

Just saw this in the new mopar performance catalog:

"Dana 44TM Axle #P659744RR HEAVY-DUTY RUBICON DANA 44TM
FRONT AXLE HOUSING
This heavy-duty axle housing is a direct replacement for your Rubicon front axle This housing features thicker wall tubes for increased load carrying capacity and improved bending strength over stock This is a bare housing, ready to accept the gears, locker and shafts from your housing
#P5160036 $995.00"

Is this their version of a prorock housing? Does it have stronger C's or just thicker tubes?

I'm wondering how it compares with a trussed and gusseted standard Rubi housing...

I'm going to assume the C's are the same. Adding thicker tubes is easy and doesn't really require any material change in production. Casting up new C's is a whole different story. I may even venture a guess that the thicker tubes may be a glimpse of axle changes for the next gen wrangler.

While the stock tubes are weak, they are already a 1/4" thick wall. When it comes to tubes, there is not a lot of strength gained beyond 1/4" and virtually none beyond 3/8". In addition, the thicker wall reduces denting or cracking, but doesn't do much for bending. A larger diameter tube is the way to gain strength, especially as it relates to bending.

Will the new tubes be better than stock? Absolutely. Stronger than a trussed stock housing? Not much. Where it would be stronger is in terms of breaking the tube. There are many pictures floating around of trussed housings where the tube broke in half. A truss will resist bending forces, but won't do much in terms of impact.

Hopefully they will hold the price line on that. That is more affordable than a Teraflex, Dynatrac, or G2 bare housing. I can handle dealing with welding gussets to the Cs if everything else has been beefed up.

A good point. And really, for a couple hundred more you could truss it and it would be pure beef.

Most aftermarket housings have beefier bracketry also. I wonder if this housing addresses that.

Wonder if they angle offset compensate for caster/pinion angle?

Yeah I think Jeep could sell the Hell out of a Ruby that you could order a V8, D 60's. I think they have enough gas sippers so a V8 in the lineup would be fine. I know I would have done it!!

Most of the usual Mopar online parts dealers have it listed for $870 or less. That's a pretty good deal depending on the remaining details look like.

That is the axle housing they use on the J8. Tubes are 3/8" instead of 1/4". No other changes. Straight from a Mopar engineer.

Agree. Apparently the J8 hubs will go on and they are much stronger. Didn't mention if that required new axle shafts though.

I wonder if you're stuck w/ Rubi-specific lockers. Since the desc says, "JK Rubicon housing/J8 tubes", I suppose you are. Fail.

Why do you say this? Whats wrong with a Rubicon replacement ARB?


Also anyone have any thoughts on going this route versus the PR44? I did a price out of a build here and looking like $4100 versus $5200-$5300 for the PR44 built. Save $1,000 this way but is the PR worth $1,000 more?

The question is if it is worth spending $4-$5k on a D44 with the same mini ball joints and weak front hubs. Same ball joints and hubs as a D30. I'm not trying to be that JY axle guy, but with the swap kits out now making it so easy, it's sort of a no brainer. For the price of a PR44 you can have a D60 and full float rear. Artec has the electronics solved as well. And the axles can be off a 2010 truck, not some old set of axles.

How many hours of labor do you have in your front axle?

There is definately something to be said for saving money by doing all the labor yourself but for some who dont have the skill or time, its so clear cut...

As a follow up to my comment above, I'm curious about something. I get that people don't all have the skills or time to build a late model axle. Is there an interest level in buying the axles ready to go? For example, a D60 and Sterling 10.5 off a 2010 Superduty. Cleaned, powder coated, brackets welded on, ABS all set to go, basically drop in like a set of new axles, but at half the price? Let's say the price was $6k and you'd have a full float rear, free spin front, etc. Even the ability to choose options like gear ratio, bracket setup, lockers, axle shafts, etc.

For me I dont have the fab skills or place to do so so direct swap is best for me. plus it would cost me $1,000 easy or more for JY axles 2010 and newer.

Another issue I have to watch is I still DD my JK so I have to maintain tire coverage so full width could be a problem costing me another $1500 in wheels.

I would love to have an opportunity to slowly build an axle and get the experience which is why this housing is tempting.....however is the ground clearance, caster, and C's better on the PR making it worth the extra $.

Nothing, other than I'd prefer a Detroit or a TrueTrac.

The answer to that is - Yes
