This new assembly replaces the O.E. strut and features a new custom tuned shock absorber calibrated to restore your vehicle's original ride and 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, bump stop, heavy duty crimping rings, and connector valve along with a dust boot to protect the strut.
