1999-2006 Mercedes S Class Rear Air Strut

Having Mercedes Air Suspension problems? If the front of your Mercedes is going down overnight or even worse, going down while being parked a short time, most likely you have at least one leaking Mercedes S Class Air Strut. While most people will think an intermittent leak down problem has to be an electrical issue, they couldn't be more wrong as this is a textbook symptom of an air strut leak. Depending on how the vehicle was stored during its lifespan, they generally last approximately 10 years before leaking starts. With all this being said, the sooner an air suspension leak is fixed, the less the repair bill will be. Still not sure what's wrong, feel free to call team of suspension sales experts. For those wanting to quit the air suspension game and make your Mercedes more reliable, install a Coil Conversion Kit and be done with the problem forever!

  • New Direct Replacement Unit...NOT rebuilt.
  • One OE-Style strut pre-assembled with a brand new strut, air spring and upper mount.

Mercedes S Class Air Suspension Help and Common Problems

Does the Mercedes S Class Air Strut come with a solenoid?

No. This Mercedes air strut does not include a replacement solenoid, but it does include new seals to reseal your existing solenoids. being in the business for over 30 years we can tell you with faith that the stock factory Mercedes solenoid was an outstanding design. They rarely fail....but MUST be resealed after removal and especially if the airbag(new surface to seal on) is being replaced.

Why is your Mercedes Air Strut better?

Times are tough for everyone, so sometimes we have no choice but to source out parts from other countries if they're not economically available through US manufacturers. Let's be honest, would you want to spend $1,000 for a pair of Mercedes OEM airbags on a 15-year-old Mercedes that's worth $6,000 with a full tank of gas? I'm guessing probably not. It's been our experience being in this business for over 30 years that there is good China stuff......and bottom of the barrel China stuff. ALL our parts, including our airbags, are parts we use and have used over the years ourselves in our own vehicles. It's quite simple, if we have a problem with a part, we won't carry it! As long as we've been in the business, we know the good from the bad and can see a junk part a mile away.

Is this aftermarket airbag as good as the Mercedes?

No. But if you do the math they're a bargain any day of the week! A New OEM Mercedes Air Strut lasts approx. 10 years and costs $500 EACH which works out to cost $50 per year. Compare that to a good aftermarket airbag that lasts approx. 8 years and costs $310 which works out to very low cost of $38.75 a year!

Is replacing a Mercedes air strut something a DIY guy could do?

It's impossible for us to know your mechanical abilities, but if you're mechanically inclined and are good working on cars, I would recommend doing this job!

Is it a good idea to replace the air suspension dryer at the same time?

Yes, it is a good idea to replace the dryer. Due to the low mounting position of the air suspension compressor on Mercedes, they have always had a problem with excessive moisture. Keep in mind that an excessive moisture problem can easily take out even a New Mercedes air suspension compressor costing $500 or more. In a nutshell, if you want to keep the air suspension but you don't want to break down constantly.....fix any leaks immediately and keep the system dry! If you're not willing to spend some money and time keeping the system up, we would highly recommend doing a spring conversion on your Mercedes.

Why does your air strut look different than mine?

The Mercedes S Class Air Strut in the picture is brand new will look just like yours when it is installed on the car.
