The Ford Expedition and Lincoln Navigator are built on the same platform. They use the same seats, however the features, colors, stitch patterns, and wiring may differ between vehicles.
The 1997 - 2002 Expeditions use the same front seats as the 1997-2003 F150. The 2003 - 2006 Expedition utilizes seats that do not come apart well for shipping, so we leave them whole. No reassembly required! Simply un-box them and bolt them in. We are currently working on a way to use the new expedition seats in the 1997-2003 F150.
