Since an air spring acts like an inflatable (and deflatable) balloon and requires high air pressure to operate effectively, you need the ability to inflate. Generally, more air (higher pressure) cushions and levels the ride of a loaded-down rig, and less air (lower pressure) returns an empty rig to a factory feeling. Onboard air systems are the answer to adjusting air pressure and come in many different variations based on the duty cycle of the system. On the light-duty end, simple inflation valves can be installed on lines that connect to the airbags. These are filled exactly the same as a tire and work well for sustained periods during which static, nonadjustable air pressure is adequate. They can be plumbed together or with individual valves. The advantage to individual valves is the ability to level out a vehicle side to side to compensate for uneven loads.

The next step is adding electric or mechanical air valves, a compressor, and an air tank to allow for pressure adjustability on the fly, via in-cab switches. There are many options for a setup like this, including a 12-valve air compressor, a CO2 system, or an engine-driven compressor. With a little bit of creativity, compressors and air tanks can be mounted so that no bed space is compromised. A desirable side-effect to having onboard air for your suspension is the ability to inflate tires and drive air tools if the system if robust enough.
