Bill R from Deland, FL said, "I have added alot of weight (probably close to 400 pounds) to the back end of my Scion and I needed something to get the back end from sagging. the Airlift leveling kit did the trick. It was easy to install, less then an hour, without the need of any special tools. If you need to stop sagging the Airlift kit will do the trick."
