The package adds a new electronic rear differential, retuned suspension, all-terrain tires and no less than seven skidplates.

Ford has introduced an FX4 package for the 2018 Expedition, targeting more than 20 percent of owners that use the SUV for off-road adventures.The 2018 model year is up to 300 pounds lighter than the previous generation, introducing an aluminum body and a redesigned high-strength steel frame. The new structure is said to improve off-road and towing abilities.

The FX4 edition adds a long list of upgrades to ruggedize the vehicle and improve traction and handling off the tarmac. Changes include an electronic limited-slip rear differential with a 3.73:1 final drive ratio, off-road-tuned shocks and all-terrain tires with thicker sidewalls.

The SUV boasts no less than seven skidplates including steel panels to protect the steering gear, transmission, engine and transfer case, with a full-length guard for the fuel tank. The gear includes a new sand shield to prevent the turbocharger intercoolers from clogging while driving over dunes, while the chin spoiler has been shortened to improve approach angles.

The package is visually distinguished by unique 18-inch Magnetic Metallic painted wheels, chrome running boards and special badging.

The redesigned Expedition and FX4 package will arrive on the market this fall.
