Detailed Description
Arnott SK-3628 is a new suspension strut and coil spring assembly built for the rear right side of the 2015-2017 Ford Expedition and 2015-2017 Lincoln Navigator. This assembly uses a twin-tube hydraulic damper with gas charge and a passive design, meaning it does not require external electronic commands from the vehicle.

Installation Notes and Tips
Fits 2015-2017 Ford Expedition, rear right, and 2015-2017 Lincoln Navigator, rear right. Verify the vehicle is equipped with Adaptive Suspension (CCD) before ordering.
