Arnott C-2663 Air Spring to Coil Spring Conversion Kit - Front and Rear

Arnott C-2663 Coil Spring Conversion Kit

Arnott C-2663 converts the factory air suspension on select Mercedes-Benz E-Class Wagon models to a coil spring setup. It is engineered for the 2003-2009 Mercedes-Benz E-Class Wagon (W211 chassis) with 4MATIC and ADS, and it uses powder coated steel coil springs with tuned dampers for consistent ride performance.

This Arnott conversion kit is built around exact-fit components for the Mercedes-Benz E350, E500, and E320 wagon applications listed below. The C-2663 also includes Arnott’s Electronic Bypass Module to prevent suspension-related dash warning messages after the air system is removed.

Product Details

Arnott’s NEW product line focuses on direct-fit suspension replacement solutions, and C-2663 follows that approach with a conversion package built for the Mercedes-Benz E-Class Wagon platform. The kit replaces the rubber air springs with steel coil springs and pairs them with matched dampers to restore a conventional suspension layout on vehicles equipped with 4MATIC and ADS. The result is a practical solution for owners seeking to remove aging air suspension components while maintaining vehicle-specific fitment.

Part number C-2663 is assembled in the USA and uses machined aluminum and polyurethane components where specified by the manufacturer. For shoppers searching for a Mercedes-Benz E350 air suspension conversion kit, Mercedes-Benz E500 coil spring conversion, or Mercedes-Benz E320 suspension conversion for the W211 wagon, this kit matches the listed applications directly.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Kit Can Address

• Failed air springs on the rear or front suspension
• Dash warning messages related to suspension faults
• Uneven ride height caused by aging air suspension components
• Compressor strain from leaking or deteriorated air springs
• Need for a conventional coil spring setup on a W211 wagon

Installation Notes and Tips

Compatible With 2006-2009 Mercedes-Benz E350, front and rear; 2004-2006 Mercedes-Benz E500, front and rear; and 2004-2005 Mercedes-Benz E320, front and rear. Front air suspension is required for the listed applications. Verify the vehicle’s 4MATIC and ADS configuration before installation and follow the service procedure for suspension system removal and electronic bypass setup.

Because this kit replaces air suspension components, the vehicle should be inspected for related wear in mounts, lines, and control components before installation. Use the included bypass module to address suspension-related warning messages after conversion.
