Also on crossover you run into issues with the drag link hitting the front of the crossmember. I used a Right hand drive JK drag link and pitman arm on a 2wd box but still had to cut a slot in the front of the crossmember to guarantee no rubbing. At the end of the day it’s still a lot better than the 4wd crossmember.
I don't really want to run more than a 35" tall tires on my Alcoa wheels, otherwise I would consider more lift.

I already have a PSC 2wd box so Crossover seemed to be the obvious choice.

Why is the 4wd crossmember so bad? Being I have a 6BT swap, I would have to run a Summit or similar Cummins swap crossmember to clear the oil pan if I decided to ditch the 2wd crossmember.
