Retire a costly, leak-prone air suspension and switch to dependable coil springs with the Arnott Industries Air Spring to Coil Spring Conversion Kit (P/N: C-3698, also written C3698). This complete kit is engineered as a direct-fit conversion for the 2004-2005 Mercedes-Benz E320, 2004-2006 E500, 2006-2009 E350, 2007 E280, 2007-2009 E550, and 2008-2009 E300, and it addresses both the front and rear of the vehicle. It converts the active Airmatic setup to a passive coil-spring suspension.

Key features:

  • Powder-coated steel coil springs paired with custom-valved shock absorbers tuned by Arnott.
  • CNC-machined aluminum seats for a precise, pre-assembled fit.
  • Patented Electronic Bypass Module (EBM) (U.S. Pat. No. 9,329,917) designed to disarm the Airmatic system and help suppress dash-panel error lights.
  • Converts active to passive and is engineered in the USA.

If failed or leaking air springs are the cause of a sagging ride, this kit replaces the air components with a passive coil-spring system. Pre-assembled units help simplify installation. Confirm fitment for your specific vehicle before ordering.
