Default Fusion 60/44 & Semi Float Rear or Dynatrac 44 and factory rear w/35 splines

2015 2 door JK Sport with the automatic, stock at the moment. Planning on going 35s-37s, 3.5" Rock Krawler X Factor and bead locks. Maybe a sticky 37 and a small stretch way down the line, and that's a maybe.

This is a 3rd play vehicle for us, and my wife needs to be able to drive this around town for fun if she wants. I also want to be able to take this to Moab and do most of the trails there, along with other major trails in the US. I live on the E Coast.

Should I :
1) get a prorock 44 and semi float 60 setup from Dynatrac, or a 44/60 hybrid and 60 semi float rear from Fusion?
2) get a pro rock 44 or 60/44 hybrid front from Fusion + 35 spline shafts and a rear locker setup for my factory rear 44?

This jeep will be 75% street fun, however when i do make those trips to major off-road parks, i want them to be successful with my family.

I have completely ruled out 1 tons due to price, weight, etc...should have bought a set of UD60s when they were 12k OTD years ago lol.

Pricing is very close on all of these from what I can tell from my spread sheet. I have to include labor in my costs, and I know going with option 2 will require me to buy a rear locker + compressor and have the guts installed eating up quit a bit of cost. Factoring that in, it gets within about 4k of a complete new axle set front and rear. Just not sure if its overkill for my application or not. It appears that the fusion 44/60 combo comes out ahead of the Dynatrac packages with a 60 center section and RCVs standard. I keep all of my dana 30/44 outer stuff of course on both of these options.

Any thoughts on all of this? Since I'm starting from stock, I refuse to sink money into the 30.

IMO, if you are going to spend any money on an aftermarket rear axle, there is no sense getting anything that is semi-float. if you can't do a full float then just save your money and lock/gear that rear D44 and move on. On the front, I'd tell you I will never buy another DT product again. I'm done with that company.

I agree with the full float, semi float you probably won’t ever have much trouble with any axle set up and locker under normal offroading, full float you shouldn’t have any trouble on heavy off roading unless you just get stupid, that’s on a basically standard road legal jeep. Once you get an off road only heavy modified and get out on some serious rocks or hill climbs, that’s a different story, everything can/ will break. But if you are going to spend some good money on an axle don’t waste it on semifloat.

just my opinion

I have been running a Prorock 44 with RCVs and a stock Rubicon 44 in the rear with chromoly axles on 37's with no issues for years. Heavy 4 door.

Would recommend this setup and you can save up for the full float 60..

I would do either full floater rear, or put forged axle shafts and locker in the stock rear D44. I bent both my stock axle flanges running 37's on beadlocks. Doing okay with Revolution forged shafts in the stock rubicon axle so far.

Front- if you need a locker anyways, just get a built 44. I'd only do the pro rock if you already have the rubicon stuff.

My add is that Dynatrac reputation aside, the semi-float 60 is still stronger than a semi-float 44. Where do you draw the line? I practice being careful offroad due to the fact in Canada sometimes we are just where a tow company cannot get to or it is cost prohibitive and we rely on other 4x4's to help out if they come along.

I "draw the line" on not spending thousands of dollars on a semi-float axle. Have you seen how the axle flange is integrated with the axle shaft? That's usually want breaks or bends. Not the diff gears. That's why I put forged shafts into my D44 and have been doing well on 37's for 30,000 miles so far. If I upgraded again, it would be full float 60's.

Yeah Zimm I agree with you. Personally the "I don't like getting screwed money wise" part of me says if I was to do this it would be a Pick A Part setup, get my axle guy here in Calgary to do the mods/adds and then install. I would put my arse on the line and say I could do a set of 60 floats for about $6500US all up with me installing. But my 44's even behind the V8 are fine and my wheeling mode says they will be fine for long as I own the Jeep.

I was looking hard at "going full tons" but it would cost $20,000 plus a new set of 8 lug wheels. I already have lockers front and rear, 4.88's, forged shafts front and rear, big brake kit, welded in "C's", raised track bar brackets.... not worth it for me on a 2015 wrangler.
