Adjustable Height KW (H.A.S) An excellent substitute for traditional lowering springs are spring kits. The predetermined lowering height is no longer a constraint on you. Even after the kit has been installed, KW H.A.S. systems enable you to modify the ride height of the car using the KW height adjuster. Not only does your car have a more dynamic appearance, the conventional dampers' responsiveness and steering characteristics also improve. With our vehicle-specific spring setup, all driver aid systems and comfort features of a factory adaptive or electronic suspension continue to function and function well. KW uses premium springs composed of chrome-silicon steel, with spring rates tailored to match the unique wheel load and OE suspension damper.

The engineering and experience of KW guarantee that the spring rates will work flawlessly with the various damper features of your factory adaptive electronic suspension. Not only do our KW H.A.S. kits employ premium materials and come with KW ride height adjustment mechanisms, but they also always feature vehicle-specific bump stops with dust protection systems to shield your factory suspension from road filth and debris-induced wear and tear. The KW H.A.S kit, like a coilover suspension, allows for continuous ride height adjustment within a tested range, which is not achievable with traditional lowering springs. When applicable, the spring perches and dust protection elements that come with the delivery are always lowered to the lowest permissible level technically, which is usually restricted by the factory dampers.
