KW (H.A.S.) Height Adjustable Spring Kits are a great alternative to conventional lowering springs, as you are no longer limited to a fixed lowering height. KW H.A.S. systems allow you to adjust the vehicle’s ride height with the KW height adjuster even after installation. Your vehicle not only gains a more dynamic appearance, but the steering behavior and response of the standard dampers also become more agile. All driver assistance systems and comfort features of a factory adaptive or electronic suspension remain fully operational and work harmoniously with the vehicle-specific spring setup. KW uses high-quality springs made of chrome-silicon steel with spring rates designed specifically for each respective OE suspension damper and wheel load. KW’s expertise and engineering ensure the spring rates pair perfectly with the different damper characteristics of your factory adaptive electronic suspension. Along with the use of high-quality materials and the included KW ride height adjustment mechanisms, KW H.A.S. kits always include vehicle-specific bump stops with a dust protection system to protect your factory suspension from wear and tear caused by road grime and debris. Similar to a coilover suspension, the KW H.A.S. kit allows continuous adjustable ride height within a tested range, something not possible with conventional lowering springs. The dust protection elements and spring perches included, when applicable, are always adjusted to the maximum technically possible lowering, typically limited by the factory dampers. With KW Height Adjustable Springs, a sporty and harmonious driving behavior can be achieved without compromising the driving dynamics of performance-oriented vehicles. As with all KW suspension products, engineers develop vehicle-specific parameters and spring specifications that undergo comprehensive testing on the Nürburgring Nordschleife.
