I'm pondering swapping axles in my TJ instead of regearing/locking the factory Dana 30/35. I can pick up a set of TJ Rubicon axles for around $5k locally that are geared at 4.10 and air locked OR I can get a set of Dynatrac ProRock 44 front and a ProRock 60 rear from a friend that are out of a JK with 5k miles on them, geared to 4.88 with Eaton E-Lockers for $10k. I know that with the Dynatrac axles they are roughly 5" wider and will have to have the TJ brackets welded on.
Which would you do? I'm leaning towards the TJ Rubicon axles since they are bolt in and are the factory TJ width.
I’m not going to engage anyone calling opinions stupid. I’ll give my opinion, and you can use any or none of it.
I went from 30/35 with 4.10’s and 33’s and put in Rubicon 44’s with lockers and 4.88’s. I put 35’s on, and it’s good, but not hugely different.
4.56 or 4.88, I think people are over thinking things sometimes.
I would wager a drink that no one on 33’s is actually that measurement, that goes into the calculator to get those numbers. I bet if they measure from center hub to ground it would be less than 50% of a 33, so essentially they should be inputting 32’s or even 31.5’s before making all kinds of declarations.
If you want to get that exact, that’s what you have to do.
The 44/60, JK, no way I’d do that, too much work and going custom for me personally.
The Rubicon axles at 4.10 would probably do you really well.
You can also sell your current axles and bring down the Net cost. Unless you regear yourself, it ain’t cheap to put new gears and axles and labor into the 30/35, not cheap at all with labor.
