Have a 06 f350 that has a 4.5" revtek lift in it.
I want to give it some rake again so when hauling the toys the weight is atually on the helper springs instead of the airbags being at 65psi just to level the truck and the helpers not touching.

The guys with 6" lift how do they accomplish that In the rear? I currently have a 5" flat block between the axles and the springs. I believe the factory was 3".

Any suggestions on how to get another 2" out of the back end?
