How to prevent the damage of air springs / How to extend the service life of air springs/struts?

We are keenly aware, that the repair of your air suspension parts is neither inexpensive nor desirable. However, what can be done to increase the durability of your parts? Here are a few tips that will help you, perhaps not to avoid the repair altogether, but to at least postpone its due.

An air strut with separable air springs

If your vehicle offers a separable air suspension (Audi Allroad A6 C5, Mercedes-Benz W164, BMW X5), you should regularly (about once a week) lift the car to the maximum position, and remove dirt with a high-pressure cleaner (keep the cleaner at a distance to the air spring about 30 cm/12 inches, otherwise water pressure can damage the air spring). The highest position may vary depending on your model and regulation options. Therefore, please test this by trying the different modes available to you (Sport, comfort, dynamic, off-road) and choose the one that sets your vehicle to the highest position. The dirt will most likely be found under the fold of the pneumatic chambers. If you find a frozen layer of bitumen on the piston guide (the part of a strut on which the air spring is installed), it is recommended to clean it as well. Whenever possible, avoid riding on fresh asphalt, as fresh bitumen mixed with sand immediately results in a build-up of abrasives on the piston and in turn contributes to accelerated wear and tear of the air spring.

A complete air suspension shock

Many cars such as Mercedes W220 or W211 are set up with a complete air strut - shock absorber and air spring visually form a complete spare part. In many cases, you can easily recognize these by the metal cups with which the air spring is tightly mounted. To best avoid any damage, we highly recommend to regularly check the condition of the dust protection seals of the air strut.

What does the manufacturer number (OEM) stand for and why do some products have more than one?

The car manufacturers assign a number for each of their products. With this number you can find the product you are looking for. When the OEM number you are looking for is listed in the respective product information, the product is compatible with your vehicle. You can find the OEM number in the product information field:



Sometimes the car manufacturers assign more than one OEM number for a product. If you can find the OEM number you are looking for in the product information, then the product is compatible with your vehicle.

What is the difference between an air spring and an air strut?

The air spring is a part of the air strut. Some vehicles (e.g. Mercedes ML) allow you to change the air spring separately. At our online shop you have the opportunity to buy either the whole air strut or only the air spring. For some type of vehicles it is not possible to change the air spring separately. In this case the whole air strut should be replaced.

What does VDS mean and how can I tell if my vehicle is equipped with VDS?

„VDS“ = Variable Damping Suspension. This system is specific to Range Rover products and similar in its functionality to alternatives like ADS (adaptive damping system) form Mercedes. Air suspension units that are equipped with this system feature a adjustable softness. This function is used in vehicles with adjustable comfort or sport modes.
