Why buy from Switch Suspension? Well let's start with the obvious one: We have a physical location in Mesa, AZ that you can come down and visit during regular hours. It's not only our retail hub, but also where you can get something done by one of our qualified installers. We also use what we sell. So if you want one of our kits, we can not only sell it to you, but also install it if you prefer. That means that we only use the fittings, air suspension kits and suspension lift kits that we use on our own vehicles, as well as our customers? rides. As a result, we only sell products that we believe in. We don't want unhappy customers; We strive for true believers in what we do and sell. Which brings us to the last point: We're enthusiasts, too. Every one of us either has owned or currently owns at least one modified vehicle. Just look at our parking lot on most days and you'll find examples of what we find cool. Sometimes it's simple, like a lifted Tundra or Chevy, while other times it's a fully modified Suburban. We even drive our projects across the country. That all means that we know better than most what you, as a customer and fellow enthusiast, wants in your suspension setup. And we've got the years and knowledge to back that up. So go ahead: Ask us a question. One of us here more than likely has the answer.
