The Mercedes S-Class W220 (1998–2005) is known for its luxury, comfort, and technology — but also for its notoriously failure-prone AIRMATIC suspension. As these vehicles age, air suspension leaks, compressor failures, and electronic faults become increasingly common and costly. A S-Class coilover conversion offers a permanent, performance-focused solution that restores reliability, improves handling, and allows full ride height adjustability.
Why Convert from AIRMATIC to Coilovers?
While Mercedes’ factory AIRMATIC system was revolutionary in its day, it comes with drawbacks over time:
- High repair costs – Replacing air struts and compressors can cost thousands.
- Complex electronics – Sensors and control modules are prone to failure.
- Inconsistent ride quality – Aging air suspension often leads to sagging corners or bouncy ride.
By switching to a high-quality coilover system, you replace all major failure points with mechanical components that are easier to maintain and tune for your driving style.
Benefits of an S-Class Coilover Conversion
- Reliability: Eliminates air leaks, compressor issues, and electronic faults.
- Adjustable ride height: Dial in your preferred stance for street, show, or performance.
- Better handling: Sharper turn-in and reduced body roll with performance-oriented spring and damper tuning.
- Customizable stiffness: Adjustable damping for comfort or sport driving.
- Improved aesthetics: Lower stance enhances the S-Class’ road presence.

Ride Quality – Comfort Meets Control
Many owners worry about losing comfort when switching from air suspension. The truth is, a properly tuned coilover setup can feel as plush as stock while delivering better road feedback and stability. The key is selecting the correct spring rates and damper settings for your driving style.
Adjustable Sway Bars – The Hidden Handling Upgrade
Included in the SLR kit, adjustable sway bars allow you to fine-tune roll stiffness at each end of the car. For luxury cruising, you can set them softer; for spirited driving, stiffen them to reduce body roll and sharpen handling.
Installation Overview
Converting your W220 to coilovers is a straightforward process for experienced mechanics:
- Safely lift and support the vehicle.
- Remove the air struts, lines, and related AIRMATIC components.
- Bolt in the new coilover assemblies.
- Install and adjust sway bars as desired.
- Set ride height and alignment.
- Test drive and fine-tune damping settings.
Coilover Tuning Tips for the Mercedes S-Class
- Start with mid-range damping settings for a balance of comfort and performance.
- Adjust front and rear ride height evenly to maintain factory weight distribution.
- Use sway bar adjustments to correct understeer or oversteer tendencies.
- Recheck alignment after any height change.
Common Questions About S-Class Coilover Conversions
- Will this affect my ride comfort?
- With proper tuning, comfort can be equal to or better than worn AIRMATIC while offering improved control.
- Is the conversion reversible?
- Yes — the kit installs without permanent modifications, allowing a return to stock if desired.
