Detailed Description

Arnott part number C-4029 is a coil spring conversion kit for the 2015-2017 Ford Expedition and 2015-2017 Lincoln Navigator equipped with CCD. It replaces the original adaptive suspension with a steel coil spring arrangement and includes strut assemblies engineered around American steel springs for a direct passive-suspension conversion. This kit is intended for drivers who want to move away from electronic suspension components while maintaining a factory-style ride height and conventional suspension layout.

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

What It Is Used For

• Replacing failed adaptive suspension components with a passive coil spring system
• Eliminating suspension warning lights after conversion
• Addressing electronic suspension faults on CCD-equipped Expedition and Navigator models
• Restoring a conventional spring-and-strut setup on the front and rear suspension
• Reducing dependence on air or electronic suspension hardware

Installation Notes and Tips

Fits 2015-2017 Ford Expedition, front and rear. Fits 2015-2017 Lincoln Navigator, front and rear. Verify that the vehicle is equipped with CCD before ordering. Follow factory service procedures for suspension disassembly, and confirm all electronic suspension functions are bypassed correctly after installation so the dashboard warning light is turned off.
