04 denali air ride

i want to do a 2"/3" drop on my 04 denali but it has the auto leveling suspension. there doesn't seem to be any other solution except for replacing the shocks and disengaging the air ride. i know that i can get a drop spindle for the front but i can't find any other solution for the rear. Does anyone have any experience or info for this? thanks

You can drop the back. Just be sure you use shock extenders so your air ride is still useable.
