Air Bags

I have been thinking of putting an Air Suspension (Bags) on my 69 Riviera, needless to say there are many manufactures who all claim theirs is the best on the market. I have pretty much nailed it down to between Air Ride Technology or Air Bag It kits.

I would really appreciate some help in regards to getting some information on the quality of the products from each company, installation, the plug/play systems and their customer support service.

This will be used at occasional shows and the car should not get more than a couple of thousand miles a year put on it. And yes cost is a consideration.

Thanks in advace for your help.
