lowering 06 trailblazer ss

any one know how to lower the back with the factory leveling system[and no i do not want to cut it up ] no coils only sleeve bags over the axel with height sensors looking for 2 inches need to retain towing capacity its my tow vehical

ive seen on navigators and expeditions a sensor relocator that tricks the computer into thinking the truck is higher and lowers the pressure in the bags achieveing a lower ride height.

any body else just trying to keep it on the front page so everyone will see it and give there 2 cents

anybody
