Detailed Description

The FCS KY020 is an air suspension compressor for select 2007-2014 Mercedes-Benz CL-Class and S-Class vehicles. It serves as the system’s air source, supplying compressed air to the suspension so the vehicle can maintain proper ride height and consistent operation of the AIRMATIC and ADS system. If your Mercedes-Benz CL550, S550, or related model is experiencing air suspension performance issues, this compressor is the replacement component to verify against the listed fitment.

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