Arnott C-2140 Air Spring to Coil Spring Conversion Kit - Front and Rear

Coil Spring Conversion for Expedition and Navigator

Arnott C-2140 is a new air spring to coil spring conversion kit for the 2003-2006 Ford Expedition and 2003-2006 Lincoln Navigator. It replaces the factory air strut setup with a passive coil spring and strut arrangement while maintaining the factory-intended trim height.

Built with steel springs and standard replacement-grade components, this conversion is designed for drivers who want to move away from air suspension service concerns on the Ford Expedition and Lincoln Navigator. Arnott C-2140 arrives preassembled for straightforward installation and does not require a spring compressor.

Detailed Description

Arnott C-2140 converts all four air struts on the vehicle to a coil spring/strut combination engineered for the Ford Expedition and Lincoln Navigator platform. The spring rate and assembly layout are intended to preserve factory ride height, making this a direct suspension conversion for owners replacing aging air suspension components. Arnott C-2140 is a practical option for 2003-2006 Ford Expedition and 2003-2006 Lincoln Navigator applications where a passive suspension setup is preferred.

Arnott’s NEW product line focuses on replacement suspension solutions, and this kit follows that approach with preassembled coil spring struts that reduce installation complexity. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Part Helps Address

• Air strut leaks that cause ride-height loss
• Suspension warning light concerns tied to failing air components
• Repeated compressor cycling from air system faults
• Uneven stance caused by worn air suspension parts
• Costly maintenance associated with aging air struts

Installation Notes and Tips

Arnott C-2140 is preassembled and does not require a spring compressor. No special tools are required for installation. This conversion kit does not include an Arnott electronic bypass module (EBM), so suspension warning light disablement is not part of the kit.

Verify vehicle fitment by year, make, model, and suspension configuration before installation. Fits 2003-2006 Ford Expedition, front and rear. Fits 2003-2006 Lincoln Navigator, front and rear.

Quality Assurance

This Arnott NEW suspension conversion kit is built as a standard replacement solution using steel spring construction and vehicle-specific fitment for the listed Expedition and Navigator applications.
