I went back and forth on this for many years. Finally I put together pieces from different company's that I thought would work best for me. It turned out great my jeep flexes like crazy and rides smooth and stable on the road.
I have been running 31's for a long time with no lift just fender trimming, and can go almost every where my friends do "TJ 4 inch RE 33's, JK Rubicon, 4 inch lift 36" and in some case places they cant. but I hit from time to time and wanted more flex. Plus I wanted to run 33's. This is what worked for me.
I have a custom front bumper with a winch, so I got rustys HD 3" front coils, for me they are perfect. I have not had other rusty's stuff but I love these higher spring rate coils. I used Iron Man lower control arms up front, and will begetting his uppers shortley. His stuff is top notch, and can really take a beating. I used HD OME rear leafs, in the back, this coupled with Iron Man 1" lift boomerang shackles gives me a great ride and wonderful flex. I have vibes at 35 mph so I ordered a wilsons fabworks SYE, hopefully it will get here soon. The vibes are not too bad, and I am at 4 1/2" in the rear, 3 1/2" up front. I have plenty of room for 33's from the cutting I did before.
This set up wont work for everyone but for me it has been great and I love it. oh yeah for shocks Im running some from a Rubicon JK, I got for free they are great.
