Arnott Industries Air Spring to Coil Spring Conversion Kit P/N:C-3552
Refresh worn ride quality with the Arnott Industries Suspension Strut and Coil Spring Kit C-4029, a bolt-in replacement for the 2015-2017 Ford Expedition and 2015-2017 Lincoln Navigator. This kit addresses both the front and rear positions, pairing struts with their matching coil springs to help restore controlled damping and proper ride height on the listed applications.
Signs the original struts or springs may need replacing include excessive bounce over bumps, nose-dive under braking, uneven ride height, or a sagging corner. Because these symptoms can have other causes, diagnose the suspension before ordering. If a worn strut or coil spring is the cause, this kit replaces those components.
