AS-2856 is an Arnott engineered aftermarket air suspension strut for the rear right or left-hand side of the 2007-2012 Lexus LS 460/08-12 LS 600h L with Adaptive Variable Suspension (AVS). This new assembly replaces the O.E. strut and features a new, not remanufactured, custom-tuned shock absorber. The Arnott strut features a new heavy-duty air bladder from ContiTech which is protected by an aluminum can along with a CNC-machined top mount and sealing cap made from aircraft-quality aluminum. This new air strut is assembled in the USA with Arnott's long-lasting seals, O-rings, bump stop, heavy-duty crimping rings, new air fitting and a dust boot to protect the shock.
