The Riaction GT1 Coilovers for the 2000-2006 Mercedes-Benz S-Class W220 deliver a premium, adjustable suspension upgrade built for drivers who want more from their S-Class W220 than the factory setup can offer. These Mercedes-Benz S-Class coilovers are engineered to pair street comfort with canyon and track capability, giving you the stance, handling, and adjustability you”ve been chasing without compromising daily driveability. Whether you track your W220 S-Class on weekends or log daily miles, this W220 coilover kit dials in ride height and damping to match how you actually use the car.
Every GT1 set features a monotube damper with 32 levels of damping adjustment, so you can tune ride quality to match the road, the weather, or your driving mood. Full-length ride-height adjustment separates preload from ride height — meaning you can drop the S-Class W220 to the height you want while preserving spring travel and shock stroke. Riaction coilovers for the 2000-2006 Mercedes-Benz S-Class are fully rebuildable and backed by a 2-year warranty, making the GT1 a long-term suspension investment rather than a disposable upgrade.
