The Air House Mini was designed to to be a Miniature version of the Air House 2.  Sometimes 5.875"-6" is just a little too large for your vehicle, that's where the Air House Mini shines!  With a maximum diameter of 5.25", it gives just enough room.  Typically that's the difference between bags rubbing and not.
With a Super Short 2" Collapsed, and a respectable 7.5" extended height,  results in 5.5" of available bag travel and even more at the Wheels with leveraged suspension!  With the smaller diameter, it will provide a firmer ride compared to the Air House 2.
Best suited for your Control Arm suspension, or Link rear system where the bags are mounted on the bar to take advantage of leverage.  Most popular application is newer vehicles with complex, tight rear suspension.
