Detailed Description

Arnott NEW C-2271 is built for Mercedes-Benz S-Class owners who want to replace the factory air suspension with a conventional coil spring setup. This conversion kit is engineered around the vehicle’s original suspension geometry and uses tuned shock absorbers, steel compression springs, and a dedicated control module to deactivate the air suspension electronics. For drivers searching for a Mercedes-Benz S430 air suspension conversion kit or a Mercedes-Benz S500 coil spring conversion kit, this part provides a direct solution for the listed applications.

The Arnott product line focuses on suspension replacement components that are designed to work as complete systems, and C-2271 follows that approach with pre-assembled parts and application-specific tuning. Part number C-2271 is also a practical option when you want to move away from recurring air spring service on the Mercedes-Benz S-Class while keeping the vehicle’s ride characteristics closer to the original air suspension feel.

What This Product Helps Solve

• Air spring leaks that cause ride-height loss
• Compressor strain from repeated air suspension faults
• Dash warning lights related to AIRMATIC failures
• Recurring maintenance tied to aging air suspension components
• Vehicle downtime caused by failed air struts or related air system parts

Installation Notes and Tips

Install C-2271 on vehicles listed as equipped with air suspension only. The kit is pre-assembled to simplify the conversion process, and the included control module is used to disarm the AIRMATIC system after the suspension changeover. Verify the vehicle’s original suspension configuration before ordering, since fitment is limited to the specified Mercedes-Benz S430 and S500 applications.

Quality Assurance

Arnott manufactures this conversion kit with application-specific shock absorbers, powder-coated springs, and CNC-machined aluminum seats for a controlled replacement setup. The patents pending module is included to address the electronic side of the conversion and help eliminate suspension-related warning messages.
