How to Install Air Suspension Compressor Dryer for Ford, Lincoln, Mercury DR-7906
The air suspension compressor is the heart of your air suspension system, providing pressurized air to the springs. When it fails, the vehicle may sag, fail to raise, or the compressor may run constantly. Replacing a worn compressor restores proper ride height and extends the life of other suspension components.
- Allow system to fully depressurize before disconnecting lines
- Do not run new compressor continuously - may need to prime system gradually
- Check for leaks at all connections before driving
