Add a 2-gallon Aluminum Air Tank to your AirIQ system to BOOST it's potential. When you need to add air to your helper air springs, air is moved from the tank to the bags immediately, instead of having to wait for your compressor to fill them directly. By changing the fitting on the tank, you can also add an air tool coupler to give you onboard air for other uses such as filling tires and other accessories. This aluminum air tank is powder coated and includes easy frame mounting brackets and tank plumbing kit.
