It was developed to fit into the applications where the Air House 2 give too much travel. Have a control arm that will hit your bag? Shock too close for comfort? Or maybe you want a firmer ride at a lower height. Air House 1 is your answer! 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.
