The Arnott designed new rear air strut AS-3234 for the 2011-2018 Jaguar XJ (X351 Chassis) fits both standard and long wheel base models equipped with rear or all-wheel drive. Arnott's struts which are completely new, and not remanufactured, bypass Jaguar's active damping and feature a custom-made and tuned premium Eibach® monotube damper 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 sleeve, heavy duty crimping rings, polyurethane bump stop, O-Rings and new, OE-inspired, dampening coil.
