I have 4" springs with a dropped pitman and I have to trim the draglink joints because my threaded adjuster is at minimum length with the steering wheel still offcenter. I can't go any shorter with this combination, I couldn't imagine how bad it would be with a zero rate up front on top of things.
It handles and steers fine for a big floppy fullsize truck. I don't wheel mine very hard so crossover is not priority now. Will be one day. I do have to clearance my fenders with 37's though.
I would avoid at all costs pushing the axle forwards with the stock push pull setup if you actually will go offroad with it. You will be very unhappy with not steering in one direction when flexed out, having unwanted steering input, and possibly breaking a relatively weak steering arrangement.
