Hello-

I just ordered a set of Currie extreme 60/60 (Full Float) axles for my Jeep 392 Rubicon. I made sure to order a high-pinion front but decided to order a low-pinion for the rear of the vehicle. This Jeep is mainly used as a weekend warrior on moderate to hard trails in my home state of AZ. It's currently sitting on a 4.5' lift and 40's as well as lots of other upgrades. Maybe I should have posted this question prior to ordering but I'm now wondering if I should have gone with a high-pinion instead. Any thoughts on this decision before I'm unable to put in a change request to switch to a high-pinion? I'd like to have a vehicle that's still usable and relatively comfortable to drive around town as well as to and from the trails.

Thanks!

You made the right choice, especially for the rear. A LP up front would be stupid and weaker, but arguably not as bad a HP in the rear. In your pic, which is typical, there's much more load on the rear axle. That's why the Bronco with 37's has a D50 in the rear. That's why Dynatrac sells D60/D80, more beef in the rear.

I see more cons with a HP rear than I see benefits.
30% weaker vs slightly more clearance. HP front, LP rear, the only way to go.

So we can all agree LP in the rear is good. When would you like to talk about it being a Dana 60?

What would the concerns be for it being a D60 rear? I liked the Currie setup as even though it’s “only” a 60, it’s still a 40 spline inner shaft giving it considerably more strength over stock and even a 35 spline. What considerations might I have overlooked with having not picked let’s say a Dynatrac 60/80 combo? Thanks!

Strength. I put Dana 60's front and rear in my 2018 3.6. I'd never go through those axles. But stepping up to the 392 you can break the 60's. So don't get trapped into feeling like they are bulletproof. Like the 80.

You definitely made the right decision for a LP rear. But, I agree with Andy, a Currie D70 or a different brand D80 would have been a better choice. Your right foot will be your best friend and if you don’t hammer down, the 60 will probably be just fine. If you are worried about hitting your rear driveshaft, get a 2.5” x 0.250” walled shaft built by Adams Driveshaft and you’ll be fine.

A HP rear is definitely for a trailer Queen, but the added driveshaft protection is appreciated in my buggy. My HP rear is a 40 spline SpiderTrax axle with a HP10 from GearWorks, which is a Ford 9” based setup. That means my pinion is even higher than a HP60 and I’ve still managed to hit the driveshaft. AZ rocks just like to jump up and eat driveshafts.:LOL:

This is my old 2.125” x 0.188” walled shaft. Took the hit without any dents, so it is now my backup shaft.

Awesome! I appreciate the feedback. I’ve got 1350’s on my current setup from Adams now and they work great. I’ll likely go with them again for this new setup. While the current setup has done well for many of the trails in Table Mesa and other “hard” trails in AZ, I also find myself being very cautious with the skinny pedal as well as lockers. As a driver, I don’t go too crazy but do like to have fun and feel as though I’d like to have the extra insurance a 60/60 setup provides. The only other option Currie has is a $26k 70/70 setup but just not sure I could justify the price but maybe I’m wrong. Again thanks for the insight!

If you are getting new driveshafts built to work with the new axles, definitely call and talk to them about the thicker walled tubes. They are great at answering questions and building what you need.

BTW, Table Mesa is a fun area. After I did Anaconda in the JL, I made the decision to step up to a buggy. Bought a YJ based rig and wheeled that for a year, now in a true tube buggy.

Lower Terminator, just before we made the turn to Anaconda. Last hardcore trip in the JL.

Don’t forget the shaved 14 bolt as a rear option. That’s likely what I’ll end up with when I can scratch together the funds. Fusion, ECGS, Advanced Driveline, Crane all have 13 bolt options.

I wish the 14 Bolt would pop out of a truck with the 72.5" width from the get go. I'd run it all day long!!!

The 3.6 or 2.0 T with a 4:1 xfer case delivers more torque to the axle than a 392 with a 2.71 xfer case. You're right it's not bulletproof. Stay off the skinny petal. 60's with 40" wheels is much better than us folks with D44's and 38's. We do fine off the skinny petal.
