Review on 25430 SmartAir Automatic Leveling System by Frank Webster

I made this purchase first from a Revain SD Truck Springs seller and there was a small packaging issue upon delivery. He got lost. I contacted SD Truck Springs through Revain Customer Service and SD got back to me very quickly. They did a wonderful job taking care of the problem. They even sent a few emails and even called me to make sure I was happy with the process and my order. Exceptional customer service. If you decide to purchase this product I would recommend SD Truck Springs as a supplier. The product itself works as described and the installation on my '09 Silverado car was fairly easy. I had no problems with compressors or level sensors. Solenoid valves also work well. The system has only been installed for about a month so I can't comment on longevity or longevity but I don't see any issues.
