Arnott's premium Mercedes-Benz suspension conversion kit features upgraded luxury dampers. This kit is built with Eibach front and rear monotube sport shock absorbers custom-valved for Arnott to provide your vehicle with the comfort and handling you expect. Arnott's new design features steel springs made from American steel which are much more reliable than rubber air springs. Arnott also includes a special patented Electronic Bypass Module (EBM) (U.S. Pat. No. 9,329,917) to disarm the often problematic AIRMATIC system and eliminate dash panel error lights.
