Lift Height Measurements

[TTLex]

I have a question for you....so you have the fabtech 6" lift and you added a 1" spacer in the rear and after market keys to the front to lift it up more. Any issues at all with driveline angles, vibration, etc, etc.?

I have the fabtech with 38's, and would like to get a bit more out of it, if It wont affect anything else.

let me know, thanks
