I have a '99 f-150 with 3" lift spindles in the front and in the near future am going to be getting Eibach Coils and new Upper Control arms that will lift my truck about another 2.5 to 3" in the front. I have the rear end stock as of now and was wondering what to do. I know Deavers would be the best thing for the rear but I am not going to have the $ for that when I lift the front. A friend suggested just to get extended shackles for the rear and leave it at that. I was wondering if that would be better than blocks or Add-a-Leafs. What would be the best way and what are some of the pros and cons of each set-up? Please help.
