Deaver Springs directed me to the following site for the HD Coil-Rite
air bags .
www.macsspring.com This company is a very old suspension shop that specializes in all of the Air Bag technology's available today , they are in fact Firestone's largest small truck supplier in North America and they supply most of the kit's to many of the stores that we all frequent in our pursuit to perfection for our SportsMobiles . John Rago is the owner and a great guy and owner of a restored Unimog that he shared with me this A.M. when I had HD bags installed .
