KW H.A.S. Coilovers Mercedes C43 AMG


For improved looks and more driving dynamics – in OEM quality.

KW height adjustable spring kits are a great alternative to conventional springs. You do not have to be satisfied with a fixed lowering as you can adjust the height with the KW height adjuster even after the kit has been installed.

Your vehicle not only gets a more dynamic look with the KW height adjustable spring kit, but the steering behavior and response of the standard dampers becomes more agile. All driver assistance systems and comfort features of an adaptive series suspension remain with our vehicle specific developed spring set up.



KW H.A.S.: Height Adjustable Spring Systems

KW H.A.S. Coilovers Mercedes C43 AMG Convertible AWD with electronic dampers


With conventional lowering springs you have to decide on the lowering from the beginning, but not with the KW height adjustable spring kits. Depending on the vehicle specific application, you can change the lowering within the adjustment range with the threaded spring perch even when the springs are already installed.

The height adjustable spring or H.A.S. kits from KW use high-quality springs made of chrome-silicon steel that are vehicle specific and adjusted to the respective standard suspension dampers and wheel loads. At the development of the respective spring kits we consider that the spring rates will perfectly harmonize with the different damper characteristics of your adaptive series suspension.

With their high quality (surface) finish and the KW height adjuster, our KW height adjustable spring kits delivery always includes the vehicle-specific bump stops with a dust protection system to protect your standard suspension against wear & tear caused by spray and salt.
