The system adjusts the pressure of the airbags while retaining the stock functionality of the system (including the 3-way dash switch if applicable). Also it involves no permanent mod's to the system (my primary goal since the system is so flawed with bugs from the factory).
Also the system also will allow you to run higher then stock settings if desired (off-roading). The only limits for the system is the limits of the factory parts.

The picture shown is the LOWEST possible setting you can have on the air system without causing sensor issues with the factory computer. Also that picture was taken on the "low mode" on the dash switch. The normal ride height is slightly higher since the "low mode" is too bumpy because its resting on the bump-stops.

Here's some pictures that show the 3 new height settings (using the factory dash switch).
