I bought this air spring for my car. I had it installed by a professional mechanic and it worked great for about a week and a half. I went outside one afternoon and saw a frame sitting on a wheel. I thought it might be a slow leak in the line or maybe even the pump. The lines have been replaced, the pump is a few months old. I towed the car back to the mechanic and he told me the air raid was bad. When it was first installed and I became aware of the problem, it was too late to remove it from the car and return it for a refund or exchange. I have to say I'm disappointed.
