This rear air spring kit from Unity is designed for 1997-2002 Ford Expedition and 1998-2002 Lincoln Navigator models, excluding rear-wheel-drive variants. It serves owners and technicians who need to restore the original air suspension ride quality on these specific vehicles.

Fits select Ford and Lincoln SUVs

The kit includes two suspension air spring bags and two replacement solenoid valve units, providing the components required to service the rear air suspension system on the listed applications. Installation returns the system to functional condition without requiring separate parts sourcing.
