Southern Air is about to celebrate their 20th year. Through those years we have taken a good idea and brought it into the new millennium. We entered, The World's First electrically operated aftermarket AC system for Rods and Customs, in new products at the SEMA Show in Las Vegas in November 1998. Since that time others followed and we continue to bring new ideas to the market such as the new "SuperFrost Pro" for the first time in this ad. This is a very affordable Heat,AC and defrost system that will fit almost any application. At only 18" overall width and approx 8 inches deep and 8" tall. Makes Air conditioning your rod more affordable. This unit features an all new Rotary controlled cable operation for selector mode. ie/ floor to dash vent control as well as to defrost!
