Air Springs

What does an air spring do?

The air spring is the spring in an air suspension system: a rubber bellows filled with compressed air that carries the weight of the car. By changing the pressure, the system keeps the car at the right height regardless of load. On some cars the air spring is a separate part, on others it is combined with the shock absorber into an air strut.

Signs of a failed air spring

The car sags on one side or one axle after standing, the compressor runs often, or a suspension warning light comes on. A hissing sound near the wheel after switching off the car can also indicate a leak, and visible cracks in the rubber are a clear sign.

Front, rear, left or right

Air springs often differ between front and rear, and sometimes between left and right. Check the position in the product description and compare the OE number. A 2-pack contains springs for both sides of the same axle.

Frequently asked questions

How long does an air spring last?

It depends on climate, driving and age. The rubber ages even when the car is not used, so many air springs start leaking after a number of years even with moderate mileage.

Can I replace an air spring myself?

On many cars it can be done with ordinary tools, but the system must be depressurised and the car lifted safely. Follow the manufacturer’s instructions or have a workshop do the job.
