how good are dana 44 and 9"

[rangerdestroyer]

im looking to do a swap on my 92 ranger im wanting to put an early bronco dana 44 and 9" in it im just wondering how they would hold up to 38"+ boggers or swampers and a heavy right foot anybody know

Not very well (especially the early Bronco variants, both of which are much weaker than their F-150 counterparts... even your stock D35 has bigger u-joints in it).

38s + heavy foot = Dana60 front and 10.25" rear.

Yep.

35" max on a 44 with a heavy foot. I'd like to think I'm a finesse kinda guy and I still break shit on 35's.

If he stays outta the rocks he'd be fine. Mud is alot easier on parts then rocks.

The EB diffs are weaker I know. Unless it comes with the 31 spline 9" which is stronger than the 28 spline version. Agreed the EBd44 is certainly weaker and uses small ujoints.

But as said above, if you don't play in rocks, and mud and dirt is your terrain of choice they can handle 38's with a heavy foot. I have (large ujoint 44/31spline 9") 76f100's d44/9", spooled front and rear, under my 86 BII and continually plant my right foot on the floor with the 91 Explorer 4.0L swapped in. So far over the past year I haven't broke anything in the diffs and I'm running brand new 38" TSL's. Knock on wood.

I also have local wheeling buddies that also run 38-40's on d44 fronts with good success. We don't have rocks or high-traction wheeling around here, so I think that makes the diffs handle 40's in my neck of the woods. Don't get me wrong here tho, I have seen them spit out a ujoint or 2 from time to time, but for the most part they handle it very well.

Just a heads up the Early Bronco never came with a 31 spline 9".

I've actually seen stock toyota axles handle 44's with a 350 pushing them around. If he would've been in rocks them axles would've blown up, but since it was just mud, worked just fine.

OP, what type of wheeling you do?

ya i had a toyota on stock with 35s and i was extremly abusive to that thing with no problems
