Swap out troublesome, leak-prone air suspension for a passive coil-spring setup with the Arnott Air Spring to Coil Spring Conversion Kit C-3271 (also written C3271). This complete front and rear kit converts an active air system to reliable coil springs, and it's a direct-fit replacement for the 2011-2013 Mercedes-Benz S350, 2010-2013 S400, 2007-2011 and 2013 S500, 2007-2013 S550, 2007-2013 S600, 2008-2013 S63 AMG, and 2007-2013 S65 AMG — see the Buyer's Guide tab for engine-level details.

  • Custom-valved dampers: Eibach monotube sport shock absorbers custom valved for Arnott, built to deliver the comfort and handling these owners expect.
  • Electronic Bypass Module: A patented EBM (U.S. Pat. No. 9,329,917) is included to disarm the Airmatic system and help suppress dash panel error lights tied to the removed air suspension.
  • Ready to install: CNC-machined aluminum seats, engineered in the USA, and pre-assembled for easier installation. Converts active to passive.
