Replaced Components
The 2018-2020 Mercedes-Benz S450 is built with the following suspension components:

2018-2020 Mercedes-Benz S450 AWD AIRMATIC Struts (x4)- a plastic and rubber bag that is fitted onto a strut that uses air as a cushion instead of a metal coil spring to hold a vehicle off of the ground and off of its wheels. These struts are controlled by the suspension control module, which is also responsible for redistributing air to the struts as a means of weight distribution while cornering. All air springs all go bad at about the same rate. If one is leaking, the others will not be far behind. For a proper repair, all of them need to be replaced at the same time.

2018-2020 Mercedes-Benz S450 AWD Height Sensors (x4) - a linkage located near each wheel of a vehicle with any electronic suspension that, either mechanically or electronically, constantly measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out.

2018-2020 Mercedes-Benz S450 AWD Air Lines- tubes that run from an air pump to the AIRMATIC struts, which carry pressurized hydraulic fluid to hydraulic struts in order to adjust the height of the vehicle, respectively.

2018-2020 Mercedes-Benz S450 AWD Compressor- if your suspension is leaking down, that means the compressor is working overtime and has likely already burned out.

2018-2020 Mercedes-Benz S450 AWD Dryer- prevents moisture build-up inside of hydraulic suspension parts.

2018-2020 Mercedes-Benz S450 AWD Suspension Control Module- a computer which is responsible for the operations of the AIRMATIC suspension system and maintaining the vehicles correct ride height.

2018-2020 Mercedes-Benz S450 AWD O-rings- Although they are the least expensive parts of the AIRMATIC suspension, they are responsible for maintaining the seal where all of the air lines connect. Be sure to replace the O-rings when repairing any air suspension system.



Suspension Failure Signs
There are classic symptoms of a failed or leaking air suspension system in the 2018-2020 Mercedes-Benz S450 AWD. Early detection of a bad suspension is the key to maintaining the vehicle's overall health. Look for an inability of the S450 to reach and maintain its proper ride height. A sudden height variance between different sides of the S450 is also a red flag. This may look like one sagging end, one inflated end, a squatting appearance, or a shifting lean from side to side. A bad suspension will wear out the air compressor; if the compressor is running too often or has already ceased working then suspension failure is advanced. At this stage, a suspension warning light will illuminate on the dash.

OEM Replacement Cost
  • Front Air Strut Assemblies ($2,000/strut)
  • Rear Air Strut Assemblies ($1,700/strut)
  • Air Compressor ($1,300)
  • Air Reservoir ($400)
  • = Over $9,000 (but that doesn't include replacing electronic components that are known to fail such as the height sensors).

Strutmasters' air to non-air suspension conversion kit saves S450 owners time, frustration, and money when the airmatic suspension system goes bad. The kit, made in America, eliminates the faulty dependency on the assorted parts that make up the original system. It comes complete with four pre-assembled coilover struts with cold-wound steel coil springs. The high-quality parts are more reliable than the originals; it's guaranteed with Strutmasters' 1-year warranty. Customers appreciate that the kit is installed in as little as one hour per wheel, and the suspension warning light turns off after about thirty minutes. The kit is a direct replacement- no modifications are needed before it's installed. Detailed instructions, online installation videos, and ASE certified technical support are just a few of the perks Strutmasters customers enjoy. The low price of the kit may be the most appealing aspect of them all; the kit costs a fraction of the price of dealership direct replacement and individual part replacement.
