Suspension Systems

What suspension systems does MAD offer?

If more is required of the vehicle chassis, we offer the solution with our suspension systems. In close cooperation with vehicle manufacturers and conversion companies, we design coil and air suspension systems for the most diverse applications. Whether it is a car with caravan, van, pick-up, camper, minibus or ambulance. Our suspension systems ensure that comfort, driving characteristics and safety remain optimal even in these conditions. So the driver's safety is always guaranteed and he can use the vehicle as he wishes.

What are the advantages of the suspension systems from MAD?

It is important to us that the suspension system is optimally tuned to the driver's desired situation. This is why we offer the most extensive range of suspension systems for passenger cars and light commercial vehicles. This means that we can recommend the most suitable system for every situation.

Our suspension systems offer many benefits to the driver and passengers:


  • A comfortable and relaxed ride for driver and passengers under all circumstances.
  • Optimal comfort, both in laden and unladen situations, thanks to an increased suspension travel.
  • Continuous and fully automatic ride height adjustment with Air Master Ultimate.


  • Optimal grip for front-wheel-drive cars.
  • Increased vehicle stability, as crosswinds have less impact on vehicle stability.
  • An appropriate suspension system leads to improved road holding and vehicle control.


  • MAD suspension systems are approved by independent certification bodies: RDW & TÜV.
  • Thanks to a constant tow ball height, a vehicle combination is prevented from swaying.
  • Optimal stability and road handling in different or changing conditions, both loaded and unloaded, increases safety for driver and passengers.

When do you need a new type of suspension system?

Although manufacturers of passenger cars and commercial vehicles provide an excellent basis, sometimes this is not enough. When more is asked of a vehicle's chassis, we offer the solution with our suspension systems. For example, when a vehicle is continuously loaded, to compensate for weight, when using a tow bar, when adding bodywork, a tail lift or truck mounted crane, with a long overhang, etc.

What is the difference between auxiliary air suspension and full air suspension?

The auxiliary air suspension provides adjustable support in addition to the existing suspension of the vehicle. This is provided by two air springs. Depending on the vehicle, the air springs are placed on or next to the existing suspension system on the rear axle.

With full air suspension, on the other hand, the air springs replace the original main suspension of the vehicle. For the operation, there is a choice of several options, whereby the Air Master Ultimate completely relieves you of any worries. You set the desired ride height once via the height sensor and the system regulates itself - fully automatically. With the Air Master Ultimate, you choose optimal comfort, stability, convenience and safety.
