How Does Airbag Suspension Work?

By Brad Nash

Thu Jul 23 2015

Suspension Airbags, such as those from Airbag Man, are essentially small, very high pressure, very tough balloons. They’re generally made up of either polyurethane or heavy duty rubber to withstand incredible weight, pressure and the forces exerted upon them at high speed. They come in systems to either assist your existing conventional springs, or replace them altogether, with the air inside the bags absorbing the kinetic energy.

Because of their adaptability, they have a variety of applications over a huge range of vehicles. Many owners of luxury 4×4‘s such as Range Rovers replace their conventional suspension with airbags to provide a softer, cloud-like ride. Because full coil-replacement airbags can also be raised or lowered, they’re often a common choice amongst customisers to provide adjustable ride height for aesthetic purposes without compromising too much on handling.

It’s not all about luxury though, and many commercial vehicles and 4WDs employ high-pressure, heavy-duty airbags for towing and carrying lighter loads while maintaining a good degree of ride quality and suspension geometry. An airbag inflated to a high air pressure (i.e. with lots of air inside) will provide a much more stable ride, capable of withstanding greater forces and pressures, and in turn being able to carry far more weight. They can then be deflated (either manually or by a switch on the dashboard) to provide a softer ride while you’re not towing. As such, they create a great compromise between ride comfort and load-carrying potential at a far cheaper price than a 4×4 Lift kit.
