Arnott C-3697 Air Spring to Coil Spring Conversion Kit - Rear

Rear Air Suspension Conversion for BMW X5 and X6

Arnott C-3697 converts the rear air suspension on select BMW X5 and BMW X6 models to a coil spring setup. This conversion kit uses powder-coated steel springs and top mounts to replace the air suspension components with a standard replacement solution for the rear of the vehicle.

Compatible with 2007-2013 BMW X5 and 2008-2014 BMW X6 rear applications, Arnott C-3697 is built for drivers who want to move away from rear air suspension components while keeping a smooth ride. The kit also includes Arnott’s Electronic Bypass Module to disable suspension warning messages after the conversion.

Product Details

Arnott’s NEW line C-3697 is engineered for rear suspension conversion on BMW X5 E70 and BMW X6 E71 platforms. The steel compression springs use open ends and a standard replacement grade to restore rear ride support without welding or modifying the original suspension. Arnott C-3697 is a direct-fit conversion solution for owners seeking a coil spring rear suspension on these BMW applications, and the bypass module addresses the electronic side of the conversion by turning off suspension warning messages.

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

What It Helps Solve

• Rear air suspension failure on BMW X5 and BMW X6 models
• Suspension warning messages after converting away from air suspension
• Need for a standard coil spring rear suspension setup
• Issues caused by aging rear air springs or related air suspension components
• Requirement for a conversion that does not involve welding or suspension modification

Installation Notes and Tips

Install C-3697 on the rear of the vehicle only. Verify the vehicle year and platform before ordering: 2007-2013 BMW X5 and 2008-2014 BMW X6. Follow the vehicle service procedure for rear air suspension removal and coil spring conversion, and confirm the Electronic Bypass Module is connected as directed so the suspension warning system is disabled after installation.

Quality Assurance

Arnott manufactures this conversion kit as part of its NEW product line for suspension replacement applications. The powder-coated steel construction, standard replacement spring design, and integrated bypass module reflect a purpose-built solution for BMW rear suspension conversion service.
