If you are looking for cheap S-Class air suspension strut (also referred as: 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 by 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 either 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. Which may be worth considering if you don’t want to worry about air struts leaking or air compressor failing.

Option 2: Airmatic to Coil Spring Suspension Conversion Kits
Average cost for conversion kit: $800-$1500
Many W220 owners love their S-Class but hate the air suspension problems. That’s why they end up converting 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 keep failing. Also if you have two failed air struts you should seriously consider converting the system to coil springs.

Symptoms of S-Class air suspension problems
- 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.
