D2 Racing RS Series Coilovers for 2007-2013 Mercedes-Benz S550 RWD (W221)

Product Details

The D2 Racing RS Series Coilover kit for the 2007-2013 Mercedes-Benz S550 RWD (W221) is built for the Mercedes-Benz S550 owner who wants to set ride height to taste and tune the dampers for the road or the track. It is D2 Racing's most popular coilover for a reason: aggressive looks, controlled body motion, and comfort that holds up on a commute.

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.
