    Backlash is a precise measurement that doesn't just get set differently based on the person who builds the axle.
    We have two guys that do nothing but build pro rock 44' and 60's in house in Washington and each one of these gets multiple Quality checks before it leaves.


    America is a great country and you get to choose what you do with your money and people are entitled to an opinion.

    One thing I have taken away from this thread and any other regarding ORE, Northridge and Dynatrac, is that no one has anything bad to say about any of these three companies, ever. Ok, so the Northridge shipping peanuts are a pain in the ass, but seriously, I don't think you truly can go wrong ordering anything from any of them.

If you chose to purchase a PR44 Housing and plan to swap your RUBICON Internals into it, then it is a different PR44 Pumpkin and will then ONLY upgrade to an ARB RD157 (35 spline). As far as it not being set up correctly, well that all depends on who you are having set it up. We do a number of these upgrades and they work perfect! The disclaimer that Dynatrac is giving is because the ARB RD157 WILL NOT work in a Conventional JK PR44 Pumpkin, it is designed to replace a RUBICON Locker in a RUBICON Pumpkin. But if you want to keep your 30 spline axle shafts to be able to have minimal "spares", just have your PR44 built that way.

    My personal opinion, I would go with a PR44 Unlimited/Extreme Housing / Pro Steer Ball Joints / ARB 35 Spline Locker / RCV 35 Spline Axle Shafts - now you did mention that you did not like RCVs, so swapping out those with another set of 35 spline axles shafts (NON-RUBICON) and to be honest, I am not 100% sure who else is making 35 spline fronts. I know the G2 Placer Golds were out there and then they were not. I think Nitro is also making them, just have not personally seen them.

Therefore I recommend going with our conventional PR44 housing, an ARB, and if you choose not to go with RCV, then Dynatrac will offer 4340, 30spl, front, 1350 joint, US made shafts imminently.

    If you are after 35 spline shafts in the front, then I would not do so unless you also upgrade the wheel ends to our Pro Series ends and 1480 shafts. That’s the same as our ProRock60 wheel end. That is a bigger step up in cost, but is the ultimate 44-class front axle. That is what we installed on the Jeep NuKizer, and other custom, low body height builds.

    The total low-cost way to go is with a PR44, re-use your Rubicon internals, Rubicon shafts, stock wheel ends, and stock brakes. The big drawback is that any time you need a replacement factory Rubicon diff for your front axle, it is about $1500 last time I looked. They are a good unit, but not anywhere near the durability of an ARB. The latest Eaton 44 E-locker is also another choice if you prefer electric activation.
    I am going to place an order for a PR44 soon and I want a housing that I can use my rubicon internals in. If I am understanding the information above correctly, my options for when my factory locker goes out is 1) replace with another factory locker or 2) get an ARB RD157 that requires new 35 spline axle shafts. Correct?

    My question for the first option is: is the factory locker a rebranded electric locker or is it a mopar part?"

    And my question for the second option is: are the 35 spline shafts readily available and compatible with the stub shafts for the JK outers?

    Bumping an old thread, but is the above correct? So you can eventually go with an arb after the factory locker fails?

    You can go to an ARB RD157 and 35 spline shafts after/if your factory locker fails. I called Steve at Dynatrac and asked him.

    Or you can get rd117 which will let you keep your stock 30spline shafts.

    I am only thinking about the rubicon replacement housing at this point, which is the one I think can only be upgraded to the RD157

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
