H&R Sport Springs for 1981–1991 Mercedes‑Benz W126 SEC/SEL six‑ and V8‑cylinder models with self-leveling (non-diesel) lower ride height to tighten fender gap and lower the center of gravity, reducing body roll and improving handling. The progressive spring design balances sportier control with maintained comfort, and H&R cites improved aerodynamics as a secondary benefit. These are shot‑peened, block‑set springs made in Germany.
