Does anyone know if you can install a 2.5 leveling and a 6' procomp/fabtech kit on a '04 Fx4 reg. cab and I would put new shocks and maybe springs in the front add a leaf in the rear but i dont know how much add a leaf? Also what size tire could you fit without rubbing if you can do it at all. I thought I saw someone on this site with one but i can't remember. If there is I would like to see the pics

THANKS
Fx4

 

It's been done. However, I think you would be much better off to just upgrade to Pro Comps adjustable coilovers and crank the preload on them up all the way.
