Tricking rear suspension???

[ARK_SWAMP_RIDER]

I'm getting a spacer lift for the front of my 4runner. It has the rear air suspension to adjust the ride height. In short, my question is that if I go with a larger spacer, will the rear automatically adjust to the up position to level out the stance? If the rear can be tricked into staying in the high position, I'll need a bigger spacer. Otherwise, I'll stick with the 1-2 inch spacer. Thanks!
