Converting air suspension?
 

How can I convert my air suspension to a regular suspension?

To remove your vehicle's Air Suspension system, you will need to remove the air compressor which powers the rear air shocks. This way, you can confidently revert back to normal shocks or struts without having to worry about hearing an air compressor running all of the time.

I believe you can locate the compressor either underneath the hood. Though, I am unsure.
