But I believe the " Air Bag suspension " does have history going back long before Ryan thought of HAMB yet, like using a SBC in anything, it isn't political correct to some of those on the site. Independent suspensions have history too as do the Chrysler alternator yet one can be crucified for using one that looks almost identical in shape but smaller from an early Jappa. There is excellent guys on there build some amazing vehicles so I just spend time with those that ain't so anal.
