Product details
This Airtech Air Suspension kit supplies the struts for a 2002-2005 Audi A4 on FWD or AWD, with two front and two rear air strut assemblies in one box. Air management is not included on purpose. These struts are designed to run with most air systems on the market, so you can match them to a compressor and valve set you already trust.
Every strut offers 36 levels of damping adjustment and an adjustable lower mount, so ride height can be fine-tuned at any pressure. The listed height range is 0-120/200 mm depending on the vehicle. The bags are crafted from high-quality metals and rubber compounds that handle daily driving and track use, with good resistance to road contaminants.
A tool kit with spanner wrenches, damping adjustment knobs and application-specific brake line brackets comes with the owner's manual. Modification to the OEM top mounts may be needed on some applications, so have a shop check that before the install begins. A complete KSport system with management is listed separately for this vehicle if you would rather buy everything together.
