Product Description

The H&R 28811-2 Sport Spring Set delivers the ideal combination of improved handling, enhanced aesthetics, and daily-driver comfort for 2015-2021 Mercedes-Benz C300 4MATIC and 2017-2020 C43 AMG 4MATIC models. As H&R's number one selling product worldwide, these progressive rate lowering springs reduce the C300's ride height by approximately 1.5 inches front and rear, while the C43 AMG lowers approximately 1.2 inches at each corner, effectively eliminating the factory fender gap for a more aggressive, purposeful stance. The lowered center of gravity combined with a slightly stiffer spring rate dramatically reduces body roll during cornering and delivers sharper steering response without sacrificing the refined ride quality Mercedes-Benz owners expect. Engineered and manufactured at H&R's ISO9001 certified facility in Germany, these springs are constructed from proprietary 54SiCr6 spring steel with an exceptional 290,000 PSI tensile strength rating. Each spring is shot-peened to increase service life by 200 percent and finished with a durable powder coat for long-lasting corrosion resistance in all weather conditions. The progressive rate design provides a comfortable ride under normal driving conditions while stiffening under load for enhanced performance when pushing harder through corners. Compatible with both factory OEM shock absorbers and upgraded aftermarket dampers, the H&R Sport Springs offer a cost-effective suspension upgrade that works seamlessly with or without factory Sport Suspension. TUV approved to meet stringent German certification standards.
