Expedition Fitment: this kit will only fit 2003-2017 Ford Expeditions that do not have Ford's optional rear air suspension system.
Mechanical Load-Leveling Suspension: ReadyLift has not tested their kit on an Expedition with Ford's Optional Mechanical Load Leveling System, and can't guarantee proper fitment of their kit or function of the Load-Leveling system after installation.
ReadyLift's ReadyGuard 5-Year/60,000 Mile Powertrain Warranty! If you're concerned about aggressive suspension or lift systems voiding your factory Powertrain Warranty, then ReadyLift has you and your truck covered. ReadyLift's ReadyGuard Powertrain Warranty covers your truck in case of a powertrain or driveline failure that's blamed on your professionally installed ReadyLift suspension or lift components of choice. The warranty covers your truck until it's five years old or hits 60,000 miles on its odometer, basically taking the place of your truck's factory warranty. The warranty covers ReadyLift suspension parts and lift kits that have been professionally installed, letting you mod out your truck without needing to worry about your warranty.
