Arnott Industries Air Spring to Coil Spring Conversion Kit P/N:C-2667
Convert failure-prone air suspension to dependable coil springs with the Arnott Industries Air Spring to Coil Spring Conversion Kit (C-2271, also written C2271). This complete front and rear kit drops in as a direct-fit replacement for the 2003-2006 Mercedes-Benz S430 and 2003-2006 Mercedes-Benz S500 (see the Buyer's Guide tab for engine-level details), swapping the active AIRMATIC setup for a passive coil-spring system so you can drive without recurring air-strut repairs.
Engineered in the USA, the kit converts the active suspension to a passive coil design and, per Arnott, costs less than a single air strut at the dealership. If failing air-suspension components are the cause of your ride-height or leveling problems, this kit replaces them with a simpler coil-spring system for the listed applications.
What does this kit do?
It converts the vehicle's active air suspension to a passive coil-spring system, replacing the air struts with powder-coated coil springs and custom-tuned shock absorbers on both the front and rear.
Which vehicles does it fit?
It is a direct-fit conversion for the 2003-2006 Mercedes-Benz S430 and 2003-2006 Mercedes-Benz S500. See the Buyer's Guide tab to confirm fitment for your vehicle.
Will it turn off the AIRMATIC dash warning light?
The kit includes a patented electronic bypass module designed to disarm the AIRMATIC system and help prevent the associated dash suspension warning lights.
Is this a front, rear, or full kit?
It is a complete front and rear conversion kit, so it replaces the air suspension at both axles.
Does it come assembled?
Yes. The kit is pre-assembled for easier installation and uses CNC-machined aluminum seats with powder-coated coil springs engineered to ride like the original air suspension.
