These new assemblies replace the OE strut and feature a custom-tuned shock absorber designed to provide a comfortable yet responsive ride. The Arnott strut includes a new multi-ply air bladder from Continental ContiTech protected by an aluminum can along with an anodized 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, bump stop, heavy-duty crimping rings, new air fitting and solenoid along with a dust boot to protect the strut.
