Our Mercedes-Benz X164 GL-Class 2007-2012 Remanufactured Air Spring Bag Strut will replace the original Front Air Spring Bag Strut. What is an air spring bag strut?- Sometimes it is called an Air Spring, Air Shock, Air Bag or Bellows. A conventional strut uses a steel coil spring but an air strut employs an air spring bag or bellow. This makes the ride more comfortable and gives the driver more control of ride height. The most common reason for an air strut failure is due to dry rotting of the air spring bag. This is something that happens over time, the rubber starts to deteriorate and causes leaks, when this happens the air bag can no longer hold air pressure. A leaking air bag can cause the strut it fits over to fail as well. The second factor of an air strut failure is the strut itself. The strut is pressurized with fluid, and if the strut begins to fail it will no longer have the same pressure to hold the vehicle. If this system begins to fail one visible sign will be that your vehicle will be lower than factory height. If Air Struts are not replaced on time it will cause Air Suspension Compressor Failure. Our Air Struts come with a **Limited Lifetime Warranty** against any manufacturer defects.

This is awesome. The air-matic shock for a Mercedes that cost less than a struct for a typical economy sedan. My mechanic couldnt' believe it. He put it in the car, drove around to make sure that he doesn't hear any funny sound & car is stable, and declared that it's as good as OEM. Perhaps better, since dealer doesnt offer lifetime warranty on it.
I have to admit, I was scared to put this in. But I did the front strut airbag combo and I also did the rear airbag and my ex 164 in three hours time in my slippers in my garage. It went rather well. The parts all fit perfectly, there were no directions shipped with the product though. I recommend searching YouTube for the install directions especially for the front strut airbag.
