Audi A4 Coilover Suspension Kit – KW Height Adjustable Spring (H.A.S.) ‘17–‘27. This vehicle-specific H.A.S. kit lowers your A4 with precise height control while retaining the factory dampers.

Multi-coated chrome-silicon springs and vehicle-matched rates sharpen steering and stability while keeping daily comfort. On cars with adaptive or electronic suspension, assistance and comfort functions remain operational. Kits include bump stops and dust protection (when applicable) within a tested adjustment range. Backed by a Limited Lifetime Warranty.
