Depends on how much lift. With the 13" of lift you are talking about, probably yes. Go through the discussion Briansshop and I had earlier in this thread. When you are going well beyond stock you can't do things the "right" way. That's when you have to find whatever gives you the best compromise.
Briansshop can probably give you an answer based on his similar experience. Based on my 3" lifted Bronco (I know, not the same...) I get a vibration in the front driveline that is pretty objectionable at highway speeds, but is OK where I usually use 4WD (I don't drive the Bronco on winter highways). So that's one way to address it.
Another I've seen (and am considering for my Bronco) is to put a double-Cardan U-joint at the diff end of the front driveshaft too (it already has one at the t.case, as does an F-350).
You MIGHT be able to make it a little better by rotating the axle forward a little (but not too much so you get your caster too far out of whack).
Or you can rotate the knuckles on the axles so you can point your diff at the t.case without screwing up your caster. Not a simple thing to do though.

What about steering? I'm assuming the crossover steering would be the most widely used method to address the steering issue with the leaf springs in the front? How's the steering box as far as durability and being able to point 40's in the right direction and not ripping the wheel out of your hands if you hit a pot hole? It has a single steering stabilizer on it now and was thinking about going with a dual setup but I also heard the steering boxes aren't that strong so if that's true was considering running this box into the ground then upgrading to a full hydro assist setup. So anyone know just how resilient these obs f350 steering boxes are along with big tires?

Yeah I've read the king pin is much easier to convert to crossover. Any reputable companies you'd recomend for the miling of the crossover mount for my ball joint Dana 60? Was thinking about going with sky manufacturing for the parts and the milling of the knuckle. Also is that a 3" reverse shackle flip you have up front?

Gotcha, we'll I'm sure I'll be in touch (if that's ok with you) with a few questions when it comes time to lift my truck because you've already been down the road I'm going down with my truck and I'm sure I'm going to run into roadblocks you hit while building your truck.
