D2 Racing RS Series Coilovers for 2010-2013 Mercedes-Benz S400 RWD (W221)

Product Details

Lower and sharpen your 2010-2013 Mercedes-Benz S400 RWD (W221) with D2 Racing RS Series Coilovers, a full-length adjustable monotube kit designed for the Mercedes-Benz S400. Set the height where you want it, dial the damping to match how you drive, and enjoy a Mercedes-Benz S400 that corners flatter and responds faster without a punishing ride.

Each RS Series kit is built around monotube dampers with separate ride height and spring preload adjustment, so you keep full shock stroke at any height. Bodies and mounts are machined from 6061 aluminum, anodized, and Teflon coated on the threads to resist corrosion, with SAE9254 springs matched to the dampers. D2 Racing backs the kit with a one year manufacturer warranty and services it in the USA, and we carry every current D2 Racing application.
