When your vehicle's air suspension system needs attention, whether it's a repair or an upgrade, understanding who manufactures the critical components is essential. The quality and reliability of these parts directly impact your driving experience, comfort, and the longevity of your vehicle. Many vehicle owners might wonder about the origins of these sophisticated systems, and that's precisely what we're going to explore. From the initial design and development to the final product, a range of expertise and manufacturing prowess is involved.
The Importance of Quality Air Suspension Components
Air suspension systems offer a superior ride quality compared to traditional coil spring setups. They utilise compressed air to support the vehicle's weight, allowing for adjustable ride height and stiffness. This adaptability means that the components must be robust, precisely engineered, and capable of withstanding significant pressure and dynamic forces. Using subpar parts can lead to premature failure, poor performance, and potentially costly damage to other vehicle systems.
Leading Manufacturers in Air Suspension
The air suspension market features several prominent manufacturers, each with a reputation for innovation and quality. These companies invest heavily in research and development to create components that meet the demanding standards of modern vehicles. Some of the most recognised names in the industry include:
- Arnott: Arnott is a globally recognised leader in aftermarket air suspension, known for its comprehensive range of replacement air springs, compressors, and complete suspension systems. They are particularly noted for their innovative designs that often improve upon original equipment manufacturer (OEM) specifications.
- Dunlop: While Dunlop is perhaps more famous for its tyres, the company also has a significant presence in air suspension technology, supplying components and systems to various vehicle manufacturers and the aftermarket. Their expertise in rubber and air control is a key asset.
- Firestone: Firestone, another major name in rubber products, is a key player in the air suspension sector. They are a primary supplier of air springs and related components, with a long history of providing reliable solutions for both commercial and passenger vehicles. Their Airide™ springs are a common sight.
- Fox Shocks: Primarily known for high-performance shock absorbers, Fox Shocks also offers advanced suspension solutions that can include air-assisted systems, particularly for off-road and performance applications. Their focus is on durability and damping control.
- Koni: Koni is a well-respected manufacturer of premium shock absorbers and suspension systems. While not exclusively an air suspension company, they often integrate air spring technology into their performance-oriented offerings, focusing on handling and adjustability.
- Sabo: Sabo is a manufacturer that supplies a range of automotive components, including those for suspension systems. They often work with vehicle manufacturers to provide OE-quality parts.
On Air Suspension: A Hub of Expertise and Quality Parts
Companies like On Air Suspension, established in 2017, play a crucial role in bridging the gap between these leading manufacturers and vehicle owners.

Retrofitting vs. OEM Replacement
It's worth noting the distinction between OEM replacement parts and retrofit kits. OEM parts are designed to match the original specifications of your vehicle's air suspension. Retrofit kits, often developed by specialists like On Air Suspension, might offer enhanced features, improved durability, or a more cost-effective solution for older or discontinued systems. They can also be used to convert conventional suspension systems to air suspension, offering a significant upgrade in ride comfort and adjustability.
When is a Retrofit Kit a Good Option?
- Availability: If original OEM parts are difficult to find or prohibitively expensive, a well-designed retrofit kit can be an excellent alternative.
- Performance Upgrade: Retrofit kits often incorporate modern technology and materials, offering improved performance, longevity, or adjustability over the original system.
- Customisation: For those looking to tailor their vehicle's suspension for specific needs (e.g., off-roading, load carrying), custom retrofit kits can provide the necessary flexibility.
- System Modernisation: Converting older vehicles to air suspension via a retrofit kit can modernise the ride and handling characteristics significantly.
Common Air Suspension Components and Their Manufacturers
Understanding the individual components within an air suspension system can also shed light on who makes what:
| Component | Primary Manufacturers/Suppliers (Examples) | Function |
|---|---|---|
| Air Springs (Air Bellows) | Firestone, Dunlop, Arnott, Continental | The flexible bags that inflate with air to support the vehicle's weight and provide cushioning. |
| Air Compressor | Wabco, AMK, Arnott, Hitachi | Pumps air into the system to raise the vehicle and maintain the desired pressure. |
| Air Lines and Fittings | Various specialist manufacturers, often supplied with kits or as OE parts. | Transport compressed air between the compressor, reservoir, and air springs. |
| Air Suspension Control Module/ECU | Vehicle Manufacturers (OE), specialist aftermarket suppliers. | The 'brain' of the system, controlling air pressure and height based on sensor inputs. |
| Shock Absorbers (Integrated or Separate) | Koni, Bilstein, Fox Shocks, Sachs, Arnott | Dampen the oscillations of the springs, controlling the vehicle's bounce and pitch. |
| Height Sensors | Hella, Bosch, vehicle manufacturers. | Monitor the vehicle's ride height and send signals to the control module. |
Frequently Asked Questions
Q1: Can I mix and match parts from different manufacturers?
While some components might be interchangeable, it's generally advisable to stick to parts from the same manufacturer or those specifically designed to work together. Mismatched components can lead to performance issues or premature wear. Specialists like On Air Suspension can provide guidance on compatibility.
Q2: Who makes the air suspension for my specific car model?
Most major car manufacturers source their air suspension components from established suppliers like Arnott, Firestone, Dunlop, or Wabco. The exact manufacturer can vary depending on the vehicle's make, model, and year. Consulting your vehicle's service manual or a specialist like On Air Suspension can help identify the original or suitable aftermarket parts.
Q3: Are aftermarket air suspension parts as good as OEM?
Many aftermarket manufacturers, including those partnered with On Air Suspension, produce parts that meet or even exceed OEM specifications.
