My wife and I used SDHQ to buy and install an Icon Suspension in our 15 4Runner. We dealt with both Red and Cliff, they asked us how we want to use our truck, our budget and then gave us different options at different price levels and the benefits of each. It was easy to get confused about the benefits of different components after reading forums, but they really helped clear it up. When we decided what components we wanted we set an install date and dropped our truck off and they got the work done in the time the promised and for the price quoted. We were extremely pleased with the service at SDHQ and will be returning go get some more mods done in the future.
