How Mercedes air suspension works –
and why it is so special
Models such as the Mercedes 600, 300 SEL 6.3/3.5, and 300 SE were equipped with sophisticated air suspension that allowed the vehicle level to be kept constant regardless of the load. This meant that the track and camber were always correctly adjusted—an advantage that conventional chassis of the time could not offer.
The systems work very reliably when the components are intact. However, over the years, O-rings and rubber seals harden, membranes tear, and leaks occur. The result: the vehicle sags – often overnight or even within hours.
A functioning system keeps the vehicle level stable for months.
If this is not the case with your classic car, have it checked now!
