An air-ride suspension is a kind of suspension that supports the load on air-filled rubber bags rather than steel springs. Compressed air is supplied by the same engine-driven air compressor and reservoir tanks that provide air to the air brake system.
Typically, air-ride suspension systems are the standard of over-the-road vehicles. Meanwhile, vocational vehicles—such as garbage trucks or dump trucks—use leaf spring suspensions because of their greater durability and capacity.
Whether it's a manual or electronic air suspension system, the benefits can greatly improve the ride of the vehicle. Take a look of some of the benefits of air suspension:
More driver comfort due to the reduction in noise, harshness, and vibration on the road that can cause driver discomfort and fatigue
Less wear and tear on the suspension system due to reduced harshness and vibration of heavy-duty driving
Trailers last longer with air suspension because the system components don't take on as much vibration
Air suspension reduces the tendency of short wheelbase trucks to bounce over rougher roads and terrain when the vehicle is empty
Air suspension improves the ride height based on the load weight and a vehicle's speed
Higher corner speeds due to air suspension being better suited to the surface of the road
Air suspension increases the transport capabilities of trucks and trailers by providing a better grip that levels the entire suspension. An air suspension system can also be adjusted for feel, so drivers can choose between a softer feel for highway cruising or a harder ride for improved handling on more demanding roads.
In the case of hauling heavy loads, air suspension offers more consistency and keeps all wheels even. The air suspension system keeps trucks level from side to side, especially in cases where cargo is difficult to level. This results in reduced body roll when turning corners and curves.
How Air Suspension Systems Work
The country's cargo shipments ride on air, and now your car can, too. Air suspension systems have long been used in the trucking world, but in the last decade or so, they've moved into the commercial world. Motorcycles, all-terrain vehicles, custom cars, performance cars -- even everyday commuter cars -- are using the suspension systems.
Changes in technology mean that systems are no longer clunky, slow and imprecise. Instead, they use fast, precision-based technology with advanced electronics that control everything from ride height to bag pressure, offering a smooth, controlled drive.
And it's about time, as the car's suspension system is an often-overlooked area. From a comfort and safety standpoint, your car's suspension is integral to how your car drives. Shock absorbers and coil springs help absorb and direct road force, maintaining wheel oscillation, jounce and rebound.
However, every time you add or take away weight to a vehicle, speed up or slow down, or turn left or right, this challenges what the shock absorbers and springs are capable of. Traditional stock shocks and springs are designed and installed with only a fixed set of situations in mind.
Air suspension systems essentially replace a vehicle's coil springs with air springs. The air springs are simply tough rubber and plastic bags inflated to a certain pressure and height to mimic the coil springs. But the similarities end there. By adding in an on-board air compressor, sensors and electronic controls, today's air suspension systems provide several advantages over all-metal, conventional springs, including near-instant tuning, and the ability to adapt handling to different situations and vary load capability.
Whether the system is manual or electronic, or installed by a weekend mechanic or a seasoned tech, air suspension can lower a car to improve its street cred, even out a heavy payload, or simply improve the ride of a vintage Detroit metal street monster.
Air Suspension System Components
Early versions of air suspension systems were relatively simple. Air bags replaced the coil springs. The bag was inflated to the correct pressure or height with an outside compressor through a valve on the bag. Changes in technology and use added more components, and control, to the system. But today's air suspension systems all have a basic stock of similar components that vary little from maker to maker. The differences come mainly in controls and ease of installation.
Air bag material has changed little over time.
The bag is a composite of rubber and polyurethane, which provides structural integrity, air-tight construction, toughness against light abrasion from road debris and sand, and resistance to salt and chemical corrosion.
The bags come in three basic shapes:
Double-convoluted bag. This bag is shaped like an hourglass. The design allows for a little more lateral flexibility than the other designs.
Tapered sleeve. This air bag performs the same as any other but is designed to fit in a tighter area and offers a little more adjustability on ride height.
Rolling sleeve. This is also a specific-application air bag. The pertinent differences between the two sleeves are really about ride height and spring control, and what's best for the vehicle and the application.
Most air suspension systems now come with an on-board compressor. The compressor is an electric pump feeding air to the bags through a series of compressed air lines. The compressor is generally mounted on the vehicle's frame, or in the trunk. The vast majority of compressors come with an attached drier. The compressor works by drawing outside air into the pump, compressing it and moving it to the bags. Outside air is often laden with moisture, and moisture can wreak havoc in a closed system. The drier uses a substance known as a desiccant to absorb as much moisture from the air as possible before the air is sent through the system.
Simpler compressor systems rely on the compressor itself to maintain, increase or decrease pressure. More advanced systems add an air tank to maintain pressure and provide an even transition between pressures. Compressors can be activated manually or automatically, and controlled solely by the driver, automatically through an electronic system, or a combination of both.
Types of Air Suspension System
The working and construction of air suspension systems are more or less similar. However, the difference in size and shape of airbags varied their usage. There are three major types of air suspension systems:
Convoluted
It contains rubber bellows with large diameters that increase the load capacity of suspension. It is often used in heavy vehicles.
Rolling Lobe
The rubber bellows are cylindrical in shape with a smaller diameter. It is often used in sedans and considered essential for increasing the ride height of vehicles.
Coil Spring Bellows
In this, the rubber bellows are installed inside the pre-installed coil springs. It is used for higher stability and ride quality.
The modern car is a marvel of engineering, and one of the most important aspects of a car's design is its suspension. The suspension is what allows your car to handle bumps in the road and keep you comfortable while driving. There are many different types of suspension systems, but air suspension is becoming increasingly popular in today's cars.
Air suspension is a type of vehicle suspension that uses air springs instead of traditional steel springs. These air springs are filled with compressed air, which gives them their name. Air suspension has several advantages over traditional spring suspensions.
First, air springs provide a smoother ride. Because they are filled with air, they can absorb more shock than steel springs. This means that you will feel less of the bumps in the road when you are driving on an air-suspended car.
Second, air springs are adjustable. This means that you can adjust the firmness of your ride to suit your preferences. If you want a softer ride for city driving, you can adjust your air springs accordingly. If you want a firmer ride for highway driving or off-roading, you can also adjust your air springs to give you the level of support that you need.
Third, air springs last longer than traditional steel springs. Over time, steel springs will sag and lose their ability to absorb shocks as effectively as they did when they were new. Air springs, on the other hand, do not sag over time and will continue to retain their initial properties.
Truck & Car Air Suspension Systems
The basic components needed to equip a vehicle with air suspension have been in common use for decades, and consist of air springs, shocks, and air supply:
Air Springs
There is no mystery in air springs, but there are a multitude of options. We utilize a wide range of air springs to custom tailor a suspension to a specific vehicle.
Shocks
Shocks are the brains of your suspension. Replacing a conventional coil spring with an air spring doesn't change this. We offer several models and available upgrades to make sure your suspension is as "smart" as you need it to be.
Air Source
Air springs need air. How to supply them with it doesn't need to be complicated, but it needs to work. We specialize in providing the most complete and dependable air supply systems in the market.

Why Use Air Suspension?
Performance customization
Everyone has their own personal idea of how their car should ride and handle. With air suspension, these wishes can be accommodated with little or no changes in components. By adjusting air pressure and shock valving, you can make the same car be soft and comfortable or firm and tight…or anywhere in between. This is what we mean by "no compromise." Drive comfortably to the track, firm up the air pressure and shock valving to go racing, readjust the pressure and valving to return home in comfort.
Ride quality
With an air suspension, you have a huge range of tuning ability for load capacity and spring rate at your fingertips… no tools or component changes needed. You can literally compress weeks of conventional spring and shock tuning into a few minutes with an air suspension that is adjustable from within the car.
Handling performance
Most air springs are very progressive: The farther you compress them, the stiffer they get. When you combine this inherent progressive spring rate with in-car adjustability, the performance potential is enormous. As with tuning ride quality as explained above, you can greatly condense the time needed to optimize the performance of your car.
Aggressive Stance
This is traditionally the criteria that make all the headlines—in the weeds, frame-dragging, spark-throwing mini trucks and lowriders. In reality, these extreme applications represent a small segment of our customers. Far more typical is the person who just wants to lower their car or truck a reasonable amount for better looks without sacrificing any drivability or durability. Raising and lowering your vehicle is just a happy coincidence of an air suspension.
