I added this to my 2011 F150 with the Firestone airbags. GREAT product and works perfect. I had 2 installation issues to overcome. First was the location to place it. I mounted the compressor to the under side of the bed, directly behind the spare tire. It's well out of the weather and well protected. Second was power supply to the controller. Key point: use the exact gauge wire as any other accessories you have connect (aka: amplifier, etc.).
Firestone Air Bags Improve Handling
The air bags made a great improvement in the ride and handling of my 2015 F-150 SuperCrew when towing my Lance 2285 trailer. I am using 10 psi in the air bags without the trailer, and 35 psi when towing the trailer, and that seems to work well. My only problem installing the kit was restricted access to the left side frame rail for installing the backing plates for the frame bracket bolts. Two brake lines were blocking the access hole so I had my favorite shop install that bracket.
