When air suspension was first introduced to the hotrod market in the mid 90’s the two way control system was the standard method of inflating and deflating the suspension. Very quickly it was learned that during cornering the outside, or loaded, airspring would attempt to transfer air to the inside, or unloaded airspring thereby magnifying body roll issues. This is where air suspension got its reputation for ill handling. Today we recommend [nearly demand] that a 4 way control system be used to control the air suspension. There are several benefits:
1) It cures air transfer problems outlined above.
2) It gives you the ability to level the vehicle. Most cars will require different air pressures from side to side to compensate for extra weight, suspension bind, or to overcome alignment changes as the vehicle is raising or lowering. [ever see a coilover car that didn’t need and extra turn or 2 on one of the coilovers?
3)It raises the vehicle faster because you have 4 orifices flowing air instead of 2.
At this point the only reason to use a 2 way system is if your vehicle has only 2 airsprings.
