Advantages of Air Suspenstion

Air suspension on trucks has huge advantages, and a few disadvantages. Most new trucks come with an air suspension option (if not as standard), and it’s available on trailers, too.

If you’re considering air suspension on a truck or trailer, here are the advantages.

Reduced noise, vibration and harshness

It’s much more comfortable for the driver – noise, vibration and harshness causes driver fatigue and discomfort, so if you can reduce this, it’s safer.

It’s easier on components – reduced vibration and harshness means better wear on other components in the truck. Trailers tend to last longer when on air suspension as the components don’t suffer as much vibration.

In short-wheelbase trucks it reduces the tendency to bounce over rough terrain when the truck is empty.

Improved fuel consumption

Some air suspension systems can optimise the ride height based on the speed of the truck and whether it’s laden or unladen. Unladen trucks usually sit higher because there’s less weight pushing the suspension down, but this is bad for wind resistance. A lower ride height means better aerodynamics because it reduces the wind resistance.

Because the suspension is better suited to the road surface, higher corner speeds can be achieved leading to time saving on routes with a lot of turns.
