Arnott Industries Air Spring to Coil Spring Conversion Kit P/N:C-3552
Swap troublesome rear air springs for dependable steel coils with the Arnott Air Spring to Coil Spring Conversion Kit C-2529 (also written C2529). This complete rear conversion kit transforms the factory air suspension on the 2007-2014 Ford Expedition and 2007-2014 Lincoln Navigator into a coil spring/strut combination, and it covers both short- and long-wheelbase models. See the Buyer's Guide tab for engine and application details.
If failing rear air springs are the cause of a sagging or uneven rear ride height, this kit replaces the air system with a reliable coil-over setup. Because it converts both sides of the rear axle, install the complete kit as supplied for balanced ride height.
What does this kit do?
It converts the rear air suspension on the listed Expedition and Navigator to a coil spring/strut setup, using powder-coated US-made steel coil springs and custom-tuned shocks.
Which vehicles does the C-2529 fit?
It is a direct-fit rear conversion for the 2007-2014 Ford Expedition and 2007-2014 Lincoln Navigator, including both short- and long-wheelbase models. Confirm your application in the Buyer's Guide.
Will it prevent suspension warning lights?
The kit includes Arnott's patents-pending Electronic Bypass Module (EBM), which connects to the vehicle's electronics and is designed to turn off dash suspension-related warning lights and fault codes.
Do I need a spring compressor or special tools?
No. The kit is pre-assembled to eliminate the need for a dangerous spring compressor, and no special tools are required. Detailed installation instructions are available.
Is hardware included?
