Arnott's completely new, not remanufactured, air strut for the rear of the Jaguar XJ series with Comfort Suspension, AS-2889, features a custom-made and tuned premium monotube shock absorber designed to provide a responsive yet comfortable ride.  The Arnott-designed strut eliminates many of the common high wear weaknesses of the OE strut such as the leaky upper seal, noisy upper mount, and the weak lower rubber seal. The Arnott strut is built with a new ContiTech air bladder, heavy duty crimping rings, O-Rings and new, O.E.-inspired, dampening coil. The Arnott design is not only more efficient, it's also much more affordable. This strut fits Jaguar vehicles with comfort suspension.  Arnott recommends replacing both Jaguar XJ O.E. rear struts at the same time.
