What does this kit do?
It converts the vehicle's active air suspension to a passive coil-spring setup, replacing the air springs with powder-coated steel coil springs and custom-valved dampers, front and rear.
Will it fit my Mercedes-Benz?
It's designed for the listed S-Class applications with AIRMATIC and ADS and without 4MATIC. It is NOT for ABC Suspension. Check the Buyer's Guide tab against your vehicle before ordering.
What is the Electronic Bypass Module?
The kit includes a patented EBM (U.S. Pat. No. 9,329,917) that disarms the Airmatic system and helps suppress dash panel error lights related to the removed air suspension.
What shocks and springs are included?
It uses Eibach monotube sport shock absorbers custom valved for Arnott, powder-coated steel coil springs made by Eibach in Germany, and CNC-machined aluminum seats.
Is it hard to install?
The kit is pre-assembled for easier installation. Follow the vehicle service information for the correct procedure and any required fasteners on your model.
