I was wondering if any body made a 4" lift for a 2003 GMC 1500HD 4x4 w/ quadrasteer? All i have found is a 6" lift by pro comp. I was alsowondering if a regular lift kit would work on a quadrasteer truck?

I am not an expert by any measure, but have lurked many a post like this. What I have heard is that if you go beyond 3-4" you have to custom fabricate quite a bit. I don't recall exactly what but maybe it was the wiring harness for the rear steer. Since the QS was such a limited production, not many lift kits cater to it. most of the posts about it are from '02 '03. No help, I know, but a little info.
