My opinion, and it is just that, an opinion, is you are heading down the road to a Frankenlift...if you need more lift it would be far more satisfactory to get the proper spring lift with matched shocks. Once you go over the 3 inch lift you will start to have to look at extended brake lines/brackets, control arms, drive shafts, and I assume you already have adj track bar or you will need it...my rule of thumb for a suspension lift properly done is about 1k per inch.

I do not consider myself a smartass. I point out the obvious, search for the truth, and speak fluent sarcasm. I am, by experience, an accomplished curmudgeon.
