S-Class W220 Aftermarket Air Suspension Struts and Conversion Kits

If you are looking for a cheap S-Class air suspension strut (airbag shock) or coil spring conversion kits, this article is for you. 1998-2006 S-Class (W220) owners, at some point during the ownership, will experience air suspension problems. Air suspension is great, but problems with it can be expensive. If you do your homework, you can save hundreds using aftermarket air springs or completely convert your W220/215 to coil springs.

If you are experiencing air suspension problems you have two options. You can replace the failed air strut with an aftermarket air strut or convert your S-Class/ CL-Class to coil springs. To replace one single air strut at the dealer, you will be looking to spend anywhere from $1000-$2000, depending on the problem, year, and location. On the bright side, aftermarket air struts for an S-Class cost between $250-$500 per air strut. Or the second option is to swap the whole air suspension to conventional coil springs for the cost of one air strut at the dealer. This may be worth considering if you don’t want to worry about air struts leaking or air compressors failing.

Option 1: Aftermarket W220 Air Struts

Average Cost per strut: $250-$500

Replacing the leaking air strut is the cheapest fix to keep the air suspension on your S-Class. At the Mercedes-Benz dealership, one air strut costs around $800-$900. Don’t panic! There are a few aftermarket S-Class air struts at a fraction of the dealer price.

When replacing struts, it is recommended that you try to keep all struts the same brand and, ideally, replace them all at once. If that’s not financially possible, keep both front and rear struts matching brands.

Option 2: Airmatic to Coil Spring Suspension Conversion Kits

The average cost for a conversion kit: is $800-$1500

Many W220 owners love their S-Class but hate the air suspension problems. That’s why they convert their S430/S500/S600/S55 to regular suspension by removing the air suspension completely. It makes sense to convert an S-Class to springs if you have a high-mileage car or if different air suspension components fail. Also, if you have two failed air struts, you should seriously consider converting the system to coil springs.

Here are some popular airmatic to coil spring suspension conversion kits. These kits include replacement struts for all four wheels. An air compressor is no longer needed.

How much does replacing an air suspension strut on a Mercedes-Benz cost?

On September 2017, we requested a quote from a Mercedes-Benz dealer to replace a front air suspension strut on an S-Class. We were quoted $860 for a new air strut and $630 to replace it. The quote was for one strut and labor to replace it.  The cost to replace the air suspension strut will vary based on your location, year, and model of your Mercedes-Benz. The typical cost will range from $1200 -$1800 to replace one bad air suspension strut.

  • If your Mercedes-Benz (S430, S500, S600, S55 AMG) is sagging at one corner, often the problem is caused by a leaking air strut (also referred to as air shocks or airbags).
  • If your Mercedes-Benz S-Class/CL-Class has lowered to the ground at all four corners, the problem is often due to a defective air compressor, replay, or valve unit.
