Arnott's new air strut for the 2002-2008 BMW 7-Series E65 & E66 chassis with Electronic Damping Control (EDC) features a heavy-duty Continental ContiTech air spring bladder and a shock designed for the 7-Series to provide ride quality and stability. Arnott assembles these new struts in the USA using the highest quality materials including a CNC-machined top mount and bottom air spring perch made of aircraft-quality aluminum, new crimping rings, O-rings, bump stop, an aluminum can, air fitting, and protective dust boot. This all new strut comes pre-assembled for an OE fit.
