My '02 Denali is equipped with the factory "Auto Ride" air-leveling system in the rear.  One of the bags is bad and the other is on it's way.  
These things are around $550 each at the dealership .  And no luck at all finding them in the aftermarket.  Does ANYONE know of a way to switch out these air-bags in favor of a traditional shock absorber, and in doing so, not confuse the computer system?  Or for that matter, does anyone have any recommendations on a resolution for this problem?

ANY HELP IS GREAT!

THANKS  

Check out Strutmasters. They offer a kit to change out Auto Ride-equipped vehicles back to standard shocks. Hope this helps.
