Air suspension can be a great feature for your Navigator /Expedition 4X2. Unfortunately, there is a downside as well. The air springs/shocks tend to crack and burst, while the other components like OE compressors, dryers, and other components are prone to failure as well.
If you are tired of replacing OE air suspension components or simply want to take away the worry, this coil spring conversion kit is right for you and your Navigator or Expedition 4X2. The coil conversion kit will allow you to replace your existing air springs with a coil spring style suspension. This will eliminate possibilities of failure, while still supplying your suspension with comfort and control.
