I wish I could be more help but this is all I know I had a 2" inch lift from online auto the springs were kings they weren'tTo bad. she moved around in the wind a lot there springs were super soft and never realy sunk over 12 months. The shocks were the let down they were ultima and they were crap the wore out in the first 2 months, I allways. Wished id put rancho adjustables on the front because on road and swayed to much off road she was a flex queen. It was just very weak I would look at aftermarket control arms for it as the coily and jimny ones arnt the best pm fatzook or some one like that. And see if he is willing to make u a set, he sounds well and truly cappable.
Sorry I couldn't give many answers hopefully some one with more exsperiance can help
