at one time in my working career, I was a professional automotive mechanic. For my 1977 Pontiac Le Mans, I entertained the the idea of installing an air bag suspension system for my ride. I began with input from other as well as searching the web. I then purchased a system for my car only to discover that the system I purchased was not going to work as well as I had hoped for. The place of business I made the purchase with did return the money short of restocking fees & shipping. I then discovered R&S Hydraulic, Robert, the owner sold me an air bag system as well as installation of the system. Upon a demonstration, a feeling of gratification came over me. For filling another phase for my low rider dream car. Complements are abundant from people who appreciate the style, color & the profile of my 77 Pontiac. R&S Hydraulic is your one stop shop. Robert will take care of business in regards to supplying the equipment as well as installing it for your car. I am very happy with the work.
