I stand by Eddie at American Air Suspension as well. His knowledge is second to none, he isnt a "salesman" at all. He is a genuine, good-hearted individual who saw a flaw in today's 'air ride industry' whereas the products that were available were limited, and costly.
I have NEVER encountered anyone who has actually done business with Eddie, and came through with a negative comment about his/her experience.
As far as "mentioning other web sites", that comment should be edited, Buddy. You havent been around long enough to know much about these cars, let alone the history of the message boards, air ride suppliers, and the likes.
I am sure the "paying" vendors here will also vouch for Eddie Spinks. They all know he is an honest, hard-working, knowledgable vendor. Sure, his operation is smaller than most of his competitors, but you know what? Often you get what you pay for...I'd pay an extra 10% anyday, if I knew no matter what, there'd be someone standing behind the parts, and there to help should things go wrong.
As far as diagnosing air ride problems, visit American Air Suspension's web site. There is a FREE trouble-shooting guide on the site, as well as detailed explanations as to the inner-workings of the air ride system.
remember folks, just because a supplier isnt a paid vendor here, doesnt mean they havent donated just as much on other sites.
Buddy-PM coming.
