The Air House 2 was designed to maximize the available space for your typical 6" Diameter bag with room to spare. With a Super Short 2" Collapsed, and massive 8.5" extended height, resulting in 6.5" of available bag travel and even more at the Wheels with leveraged suspension! More travel then most bags in the same diameter class. Best suited for your Control Arm Front suspension, or Link rear system where the bags are mounted on the bar to take advantage of leverage. No Center Ring Single bellow construction greatly increases the stability of the air spring allowing for increased angle and load applications without the banana center kick out. Maximum Outside Diameter when compressed is 5.875" and will shrink down to about 5.5" when inflated. Minimizing frame cutting in most applications. With the added stability there is a very noticeable reduction in vehicle "sway" compared to a typical double convoluted.
