It is listed for 2007-2011 Mercedes-Benz CLS550, 2003-2009 Mercedes-Benz E320, 2006-2009 Mercedes-Benz E350, 2007-2009 Mercedes-Benz E550, 2006 Mercedes-Benz CLS500, and 2003-2006 Mercedes-Benz E500, all in the front left position and for Airmatic-only vehicles without 4Matic.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
