This new coil spring conversion kit was exclusively designed for the Ford Expedition and Lincoln Navigator. The conversion kit converts the rear air suspension to a more reliable coil spring/strut combination. These aftermarket springs are designed to maintain the factory-intended trim height of your vehicle. This kit features superior quality replacement components including powder-coated US-made steel coil springs and custom-tuned shocks.
To maximize efficiency and safety, Arnott's coil spring kit is pre-assembled and ready for seamless installation, eliminating the need for the use of a dangerous spring compressor. No special tools are required.
This air-to-steel spring suspension kit also includes Arnott's new patented Electronic Bypass Module (EBM) (U.S. Pat. No. 9,329,917) technology to reliably eliminate dash panel suspension related fault codes. This pioneering technology, exclusively from Arnott, easily connects directly to your Ford Expedition electronics in a matter of minutes. This conversion kit fits both short and long wheelbase models with load leveling.
