So i just bought a Fabtech 6" Kit used. My truck sits level as it is if not a little low in the back. I'd like to level this out and not drop the torsion bars a whole lot. My ideas to remedy this is swaping the 4" fabtech kit lift blocks with some 5" blocks and throw an add-a-leaf on top of that.
My questions are:
1. Is it safe?
2. Will i need to stretch the driveshaft?
3. Will i need to extend the brake lines and if so, does any sell a kit for the 97-03
