I used Rustys 3.5 HD springs in the front, with IronMan Fab Control Arms, and OME HD 2" Springs in the rear, with 1" Ironman Fab boomerang shackles. Im using edelbroch? shocks off a 2007 Rubicon JK, it rides so smooth, eats the bumps, and flex is amazing. no issues at all, I did alot of research while piecing together a kit, took me 3 years to figure it out but it was worth it. A buddy of mine runs RE and I think the ride sucks. the control arms are not near the quality of mine, and I spent about 750. all said and done. which was less then his kit without shocks. another guy I run with runs BDS, man thats some coin. I have zero fear that anything on mine is going to break, and I beat the crap out of it. If you worried, Iron mans stuff has a lifetime warranty for a few bucks more. It is beefy!
