What Is An Air Suspension System And How Does Its Work

The use of an air suspension system can be both automatic and manual. This is a type of hydraulic lift which makes the engine of cars to rise up by providing an adequate degree of compression. It makes the car to have more power and more stability. To make this system, it consists of a pump that runs in a radiator at the back of the car. A piston is used by the motor which helps in keeping the piston at one position as long as the load is on the car. As soon as one leg of any car is lifted, there is no need for an electric brake. As soon as there is a load on a vehicle, there will always be an electrical brake.

An Air Suspension System

Difference between independent and automatic air suspension

The difference is between an independent and automatic air suspension is that the former is operate manually while the latter is automatically operate in most cases. In case you are using the automatic air suspension system, when you press a button, the system does all the work automatically and this means that the car will maintain its speed.

There are a number of ways through which you can find out if your car has automated or an automatic air suspension in it. When you press the accelerator at high speed, it triggers an electronic control unit to check the throttle and then adjust the pressure. If your system is not working properly (even in some cases because of worn-out parts), then you may need to replace it. However, this does not result in any problem since you will still get the desired performance. You can find various types of air suspension systems in automobiles today.


Depending on the end user’s needs, air suspension can be utilize for a variety of purposes. An air suspension system can be employed in a variety of ways due to its high adaptability.

For Show Purposes, Adjustable Ride

Height Going to air out your vehicle is one of the most prevalent uses for air suspension. This signifies that the car owner simply wants their vehicle to reach a certain height but does not want to drive at that height all of the time. Because of its on-the-fly adjustability, air suspension makes this incredibly simple.

Preventing Truck Squatting When Towing/Hauling

Another main example is to keep your truck’s rear from squatting while towing or hauling. Trucks can be outfitter with rear air shocks that inflate when the truck is carrying a large load. This keeps your truck level, reduces stress on components like your driveshaft, and improves fuel economy and wind resistance.

For Specific Purposes, Raise/Lower Vehicle

Last but not least, air suspension might be use for specific applications. An air suspension system could be a terrific addition to make life easier if you need electronic-control adjustable suspension to clear obstacles or to allow anything to be put into your car.


Air suspension kits will provide you with significant benefits over the factory suspension setup. While they are more expensive than the ordinary suspension system.They are definitely worth it for individuals who want to completely tailor their rides.

More Comfortable:When compared to regular shocks and springs, air suspension will deliver a more comfortable ride. When inflated, the air shocks absorb more vibrations, resulting in a smoother ride.

Customization:One of the most obvious reasons that most individuals install an air suspension system is to properly adjust the ride height of their vehicle. Unlike any other suspension technology on the market, air suspension allows you to tailor your vehicle.

Less Wear On Suspension:Because air suspension absorbs the majority of road vibrations, your suspension will last longer. When compared to a standard suspension setup, this can assist some of your usual wear items live longer.

Types of Automatic Air Suspension System

  1. Manual Automated

There are two kinds of air suspension system – Manual and Automatic. Depending upon the way that is maintain, and the type of the vehicle will determine the choice of which to go with. Each type will give different advantages over the other. For example, when choosing the Type A or B vehicle, one must decide whether they want a simple auto, advanced one, or one that goes beyond one level higher than the others. There are many options available for selecting the kind of vehicle one wishes to buy. Many people prefer choosing their own choice of models since it allows them complete independence. The most common model of vehicles are Audi Volkswagen, Mercedes Benz, Porsche, BMW, Honda, Porsche, Ford, Volvo, Hyundai, Nissan, Mitsubishi, Renault, Toyota, Toyota Yaris, Suzuki and Ford Focus etc.

All these manufacturers provide similar specifications which enable users to choose from. Therefore, all the features and quality which a customer could expect within a particular product is what exactly happens within the manufacturer’s specification. Some of these features include; torque, horsepower, weight, transmission, suspension, wheel size, fuel tank capacity, aerodynamics, body color, engine capacity, weight, age of the engines, among many other things.

Pros & Cons


  • Increased driver comfort as a result of reduced road noise, roughness, and vibration, which reduces driver fatigue
  • Reduced vibration during heavy-duty driving means less wear and tear on the suspension system.
  • When unloaded, decreases the bouncing of trucks with short wheelbases on rough roads.
  • Higher turning speeds are possible because the air suspension is better adapted to road conditions.
  • Air suspensions have a wide variety of spring rates and load capacity, allowing for instant customization. The flexibility allows you to get the ride load and ride height in a matter of minutes.
  • Adapting to diverse situations: changing spring rates and performance customization equip your vehicle with limitless performance possibilities, enabling real-time tuning and a cushiony ride for improved comfort on a bumpy piece of road.
  • Towing: The technique allows trucks and heavy vehicles to manage heavier loads more easily. Drivers can improve ride comfort by increasing the stiffness while pulling heavy loads.


  • Leaking is a frequent weakness in all air suspensions. When the system can no longer contain air, it will become flat. Clogged airlines are another typical source of air suspension issues.
  • Initial costs: It is an additional cost when purchasing a car. Only luxury cars, high-end cars, and select SUVs come equipped with air suspension.
  • Maintenance will be more expensive than with normal coils and shocks.
    Because of the complexity of wiring, connections, and hose installations, installing an air suspension will take longer.
  • The installation itself necessitates the usage of several tools. So employing a skilled mechanic is the best alternative to ensure vehicle safety and integrity.
  • If not properly maintained, can cost three times as much to fix as a leaf suspension system over a ten-year period.
  • The weight of the system is heavier than the weight of the leaf suspension, which may affect fuel efficiency.
  • Damage from rust or moisture from the inside might cause air struts or bags to fail.
  • The air suspension tubing that connects the air struts or bags to the air system has failed.
  • Failure of an air fitting due to damage after first installation or occasional use.
