So from reading Wayoflife's post about stock rubicon axle tube carnage, and then reading that there is a heavy duty tube option for the prorock44, I need to ask... what are all the options from Dynatrac for JK housing replacement?


What are all the current options for the pro-rock and trail series 44 housings?

What future options might be in the works (if any)?

Does the trail series housing include the upgraded C's?

Is the center section of the trail series housing physically larger than the dana casting?


I have looked at the Dynatrac website and (maybe it's me, but) the options and specifications are not all clear, especially concerning the trail series 44.

Personally, I would like to buy a trail series 44 if it can be had with the larger tubes, heavy duty C's and a beefier center section than the dana.

I've listed below the specs of the Trail Series 44 front axle.

High-Pinion, Heavy-duty front Dana 44 Housing
4.10 ratio, New Generation Dana 44 Ring and pinion gears
Electric Selectable Locking Differential
Heavy Duty 12.0" Disc brakes included (Compatible with most 15” aftermarket wheels)
Larger and thicker 2.75 x .375 wall DOM housing tube assemblies
50% Thicker Steel, 3/16" Fabricated suspension brackets
New Generation, Extra large 1350 axle joints and shafts
5 on 4.5, Stock XJ, YJ, TJ wheel bolt pattern
Stock XJ, YJ, TJ width
Compatible with Stock XJ and TJ steering linkages
1310 Input Yoke is compatible with most stock Wrangler and Cherokee drive shafts
Standard JK end forgings ('C')

Options-
Choice of ring and pinion ratio (4.10, 4.88, 5.13, and 5.38:1 ratios
13.25” front, and 12.5” rear disc brake assemblies with parking brake
5 on 5.0”(JK) wheel patterns available

Now that you've seen the Trail Series 44, you need to understand the focus and evolution of this product. Originally, it was not planned as a replacement for a JK. This product was based on a JK (or rear) that was needed to fit a YJ, XJ or TJ. When this was designed the PR44 was not even being considered.

Today, while the Trail Series 44 is still a good option for the YJ, XJ or TJ guy, the PR44 is a much better, and more cost effective, option for the JK.

ProRock 44 options-
Gear ratio of choice
Custom width
Custom brackets
Bare tubes
1/2" wall tubes
Std Dana 44 end forgings
ProSteer Ball joints
RCV axle shafts

Thanks for the quick reply! Someone had told me that the trail series could be bought as a bare housing with the upgraded C's... I guess he was smoking something.

It's clear that the PR44 housing is the one to get! I hope you're ramping up production on these.

Any time-frame yet on the new housings with corrected caster?

Dynatrac

We are working on it now and I should be able to make an announcement very soon.

So do you have the standard pro rock 44 or the extreme duty pro rock 44?

I Just called Dynatrac and we have the Standard pro rocks. For the even more beefed up Pro rock it is a extra $100.
