Chiming in late lol.
I run 6" up front on soft springs, a stock sway bar and home-made extended end links (with pins and R-keys), and a FA600 pitman. No sway bar in the rear at all, stock shocks back there (its SOA swapped), and hydro shocks in the front.
When I aligned mine the first time I used stock size tires, and switched to 33's on 5x8's later. They had a 4.5 backspace and ran beautifully. Later I went to 15x10's on a 3.75 backspace, and it didn't like that at all lol. Also my wheel bearing life went to crap too. I think the leveraging effect on the TB with the contact patch moved out some causes the alignment to misbehave. Also, I found that "being in the green" on the alignment rack doesn't always equal a great drive. My toe and camber lean to pretty much zero.
Sorry if there's nothing new here, but this shows you dont have to spend a ton to get these lifted trucks drivin' right.
