ToyTec Radflo Kit help

I have the Radflo kit with extended coilovers and LR upc. I drove and tested fully with the factory tires before switching. At the factory setting the truck drove better then factory and tow was only correction needed. I installed 275/70/18 AT2 yesterday. Heres the issue. I was trying to get a little extra clearance and turned coilovers up and think I may have them up too much. We were able to push tires forward during alignment. Truck drives great but solid as hell now and there is a pop sound when I go over speed bumps only. Doesnt do it on dips.

Can someone with same coilovers check the distance from top of jam nut to top of threads please. From factory mine were 2 1/8th. I know each truck will be different just looking for a starting point. I want truck as level as possible.

 

Think what I'm trying to find is mine are 2 1/8 when recieved and if I wanted to level truck would I crank it down 1/4inch per 1/2 of lift or something. I know it's general but think I got to a point where I was cranking and truck wasnt lifting and now rough.
