A turbo kit would be worth it if your willing to change alot of things, that includes a tune on the pcm or a stand alone system for fuel management, youd probably need some stronger ds's to, along with tc mods and basically a complete overhaul of the drive train, but if you have the money and you want to do it it would be a pretty interesting build

Exactly what I was thinking. A stock 44 is only good to about a 37 with a stock motor. Throw in a stroker with a turbo and some big tires and expect to break. Like I stated earlier I've broken chromos on mine with 35s and a stock 4L.

With 33s. Less with 35s. I have seen it and ran several 44s, not in XJs though. D44s have been a good choice for wheelers since they started putting them in Jeeps in the 40s. And I have been wheeling since probably before you were thought of.

Just going by what most people say. They wouldn't hold up around here either, at least they haven't for me and I don't have 37s. Of course I can't say much for 44 rears since I've never ran one, just fronts and then only Ford HP versions.

400hp on 35s with a 44 you would have to have pretty built axles. who has that much hp and still runs that small of a tire? most run 37+ and with no less then a 60/14 combo or a fabbed 9"

Even a 35 spline D60 is only rated to 38" with a locker. You can go more if you don't run lockers. Any axle that is open will handle tires that are quite large. It is the lockers combined with a heavy foot that kill it. If you want to run 37s on a 44, you need to go to 35 spline alloy axles. Then you can do it. There is only so much any axle will take. You can break Rockwells too if you try hard or are just plain stupid.

The point is experience. I have been around literally hundreds of rigs that have been raced and wheeled that had 44s in them. Many of those rigs were pulling wheel stands off the line. There were many more running big blocks with enough horsepower to require large fuel lines to feed the carbs. I had a front 44 that I made when it was a very rare thing to have. They do have their limits, but they are not as fragile as you are saying. Of course they can be abused with the wrong gear ratio and a heavy foot on a locker or spool. Also, the early ones had very course splines which were not as strong as later ones. They went from 10 splines to 19 to 27 splines. At each point, there was an upgrade in axle strength. As said, a 10 spline in an early waggy axel can be broken fairly easily in a heavy rig. But the 27 spline is much stronger. But you can run 33s with as much hp as you want. They are not quite so tough with 35s, but certainly doable if you wheel with a little intelligence and lack of beer.

37s on a 44 id definitely run chromoly shafts with some 300m joints and full case locker. would probably burn in a truss as well
