Arnott's replacement Lincoln rear air spring for the Ford Expedition and Lincoln Navigator is manufactured with a new heavy-duty air spring bladder from Continental ContiTech. Each air spring is assembled and tested in the USA to ensure the highest standard of quality. Arnott's new aftermarket air spring is so heavy duty, it is backed by a Limited Lifetime Warranty. Each air spring includes a new seal kit. Arnott recommends replacing both rear air springs at the same time.
