This new, not remanufactured, assembly replaces the OE strut and often problematic adaptive damping and features a new custom-tuned shock absorber calibrated to provide an excellent ride and outstanding performance. The Arnott strut includes a new air bladder from ContiTech protected by an aluminum can along with a CNC-machined top mount made from aircraft-quality aluminum. This new air strut is assembled in the USA with Arnott's long-lasting seals, O-rings, bumpstop, heavy-duty crimping rings, new air fitting and connector valve along with a dust boot to protect the strut.
