Rear Coil Spring Conversion for Expedition and Navigator

Arnott C-2529 converts the rear air suspension on select Ford Expedition and Lincoln Navigator models to a coil spring and shock setup. It is built for 2007-2014 Ford Expedition, rear and 2007-2014 Lincoln Navigator, rear applications, with factory ride height retention in mind.

This NEW Arnott line kit is engineered for drivers looking to replace rear air suspension components with a more conventional steel spring arrangement. The C-2529 part number is designed for direct electronic integration through Arnott’s bypass module, helping eliminate suspension-related dash warnings after the conversion.

Product Details

Arnott C-2529 is a rear suspension conversion solution for the Ford Expedition and Lincoln Navigator. It replaces the rear air suspension with a steel coil spring and strut combination while preserving the vehicle’s original ride height targets. The kit uses black steel compression springs and custom-tuned shocks to provide a conventional rear suspension layout for these full-size SUVs. Arnott’s NEW product line focuses on replacement suspension components, and this kit reflects that approach with a preassembled design and an electronic bypass module that connects to the vehicle electronics to turn off suspension warning lights.

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

Common Problems This Kit Addresses

Rear air suspension fault codes on the dash
Failed or aging rear air springs
Compressor-related suspension concerns tied to air suspension systems
Uneven rear ride height caused by worn air components
Need for a simpler rear suspension setup on Expedition and Navigator models

Installation Notes

Arnott C-2529 is preassembled to reduce installation time and eliminate the need for a spring compressor. No special tools are required. A detailed installation manual is available, and the included bypass module connects directly to the vehicle electronics to address suspension warning messages after conversion.

Verify rear fitment before ordering: this kit is not for Navigator L or Expedition EL models.

Quality Assurance

This Arnott conversion kit uses powder-coated U.S.-made steel coil springs and custom-tuned shocks for the listed applications. The NEW product line designation identifies it as a new replacement suspension solution from Arnott.
