Planning extended travel remote reservoir Icons / UCAs up front (07 GX/KDSS) while tricking the rear airbags for about 1" of lift until I have the toy-money-fund ready for rear coils and piggybacks. Am I going to be alright playing around in the desert with the OE rear suspension, or am I likely to see abysmal ride quality or premature airbag failure from running them overinflated on washboard roads?
