Arnott Industries Air Suspension Spring P/N:A-2504
Level out the rear ride and restore proper air suspension height with the Arnott Industries Air Suspension Spring A-2735, a rear air spring assembly that drops in as a direct-fit replacement for the 2003-2006 Ford Expedition and 2003-2006 Lincoln Navigator (see the Buyer's Guide tab for engine-level details). It replaces a leaking or sagging original rear air spring so the suspension can hold and adjust ride height as designed.
If a failed rear air spring is the cause of a sagging corner, uneven rear ride height, or an air suspension warning, this assembly replaces it. For best results, Arnott recommends replacing the rear air springs in pairs for balanced ride height.
