Suspension Question

[autiger1102]

Hey Guys, I am new to this site. I have a question. I have an 06 F250 4x4 Crew Cab King Ranch with an Icon 2.5 inch leveling kit on it. I have the Adjustable Pan Rod and 4" blocks in the rear. I am wanting to put the TEI 1" upgrade on the truck but Icon doesn't make a 3.5" drop bracket. I found a 1" spacer and 3.5 inch radius arm drop bracket kit at readylift.com and didn't know if that would work with the leveling kit that I have now? I called Icon and they said that I could add the upgrade and I wouldn't need the drop brackets but that I might need new caster cams, but they said that as long as I was staying under 4" that I would be fine. I was thinking about buiying the TEI upgrade from Icon and then buying the radius arm drop bracket kit from readylift. I know that sounds like a little extra coin to spend on something but the spacers that come with the readylift kit are made of 6061 T6 billet aluminum and the ones from Icon are made of steel. I don't know what to do . Is there anybody out there that can help? Any response or information would be greatly appreciated.
