Understanding Air Shocks and Their Impact on Vehicle Suspension Systems

What Are Air Shocks?

Air shocks are a unique type of suspension component that differ significantly from the more familiar mechanical springs and dampers found in many road vehicles. Where traditional parts use strictly mechanical means to absorb impacts and maintain ride comfort, air shocks incorporate adjustable pneumatic elements to achieve a similar – and often superior – result.

Distinguishing Air Shocks from Traditional Suspension Components

Fundamentally, air shocks are a form of adjustable shocks that use air pressure for cushioning and maintaining proper vehicle ride height. While mechanical springs – such as coil springs and leaf springs – offer a fixed rate of compression, air shocks boast the ability to adjust to varying load conditions and road surfaces. A traditional suspension setup is usually composed of a spring that absorbs road bumps and a shock absorber that reduces the resultant vibrations. Conventional steel springs and basic shocks work well but remain static in their operation, with little to no adjustability.

In contrast, air shocks use a chamber filled with gas - typically nitrogen - and a sealed column of hydraulic fluid to combine the roles of spring and damper. They allow the driver to control the firmness of the ride, a luxury that regular compression-based springs do not afford. This tunability enables air shocks to provide a smooth ride under light loads or a firmer setting when carrying heavy weights, such as when a truck is equipped with a heavy tire carrier or a car carries a trunk full of items.

The Mechanism behind Air Shocks Operation

The operation of air shocks involves the inflating and deflating of an air bag inside the shock to alter the pressure. When inflated, the air bags lift the vehicle, increasing ride height and often improving the overall experience by smoothing out a larger bump or adjusting for increased drag from additional weight. To adjust for a heavier load or for stability during activities like drag racing, a higher air pressure is used, providing additional lift and firmness. This capacity is a clear advantage over springs, which can only compress and rebound at a predetermined rate.

On the other hand, if the vehicle needs a lower center of gravity or a softer ride, deflating the air shocks results in a compressed height and a plusher feel. Air springs and pneumatic valves manage the flow of air and maintain the correct pressure based on the parameters set by an electronic control unit or adjusted manually. This feed of air can come from an onboard air receiver tank, which makes changes to ride height and firmness a matter of pushing a button or flipping a switch, saving extra time and effort.

However, there are potential drawbacks; if not set up properly, a harsh ride can ensue. Issues like air line failure or valve problems can lead to failure of the system. Cost is also a factor – air shocks and their installation can be pricier compared to regular shocks, and they may require more maintenance. Additionally, finding the correct air pressure often involves a period of adjustment; for example, setting a too low figure like 26lbs might result in a tad of tire scrub against the fender.

For enthusiasts and professionals alike, the allure of air shocks comes down to their capacity for customization and control. Whether adjusting the suspension for routine commuting or prepping for a full load, air shocks offer a wide range of settings to fine-tune the riding experience. This dynamic capability is why many are firm fans of air shocks, despite the extra cost and potential complexities of managing an air suspension setup.
