So if you want to lift it for 35's and up, is this possible with the ACH or are you replacing with coilovers upfront and coils in the rear?
A lift will not help you run larger tires. They still have to fit the wheel's range of motion. Lift doesn't change where the wheel goes. On the 200 series, folks are running 35s & 37s on their AHC truck. One guy is running 40s with a lot of custom fab.
