Arnott's new rear air spring for the Ford Expedition and Lincoln Navigator is manufactured with a new heavy-duty air spring bladder from Continental ContiTech. Each replacement air spring is assembled and tested in the USA to ensure the highest standard of quality. Arnott's new air spring is so heavy duty it is backed by Arnott's Limited Lifetime Warranty. Each Lincoln air spring includes a new seal kit. These air springs should be replaced in pairs.
