The H&R Sport Spring kit for 2006–2011 Mercedes‑Benz M‑Class (ML350/ML500/ML550/ML63 AMG; W164) without air suspension lowers ride height to improve stance and reduce body roll. H&R’s progressive rate design aims to keep ride comfort while sharpening handling. Built from 54SiCr6 spring steel and shot peened in Germany, these springs are a popular single-part suspension upgrade for a more planted feel.
