If you're looking to take your ride to the next level, the KW Height Adjustable Spring (H.A.S) kits are a game changer. Forget about being locked into a fixed lowering height like with those old-school lowering springs. With KW’s H.A.S. system, you get the freedom to tweak your vehicle's ride height even after installation. It’s like having your cake and eating it too—your car looks sharper, and the steering feels way more responsive.

One of the best parts? All those fancy driver assistance features and comfort settings that come with your factory adaptive or electronic suspension? They still work perfectly with these springs. KW knows their stuff, using high-quality chrome-silicon steel springs that are specifically tuned for each vehicle’s OE suspension damper and wheel load. So, you can trust that the spring rates are spot on, matching seamlessly with your factory setup.

These kits also come with vehicle-specific bump stops that have a dust protection system, which is a nice touch. It helps keep your factory suspension safe from the wear and tear of road grime and debris. Think of it as a little insurance policy for your ride. Just like a coilover suspension, the KW H.A.S. kits let you adjust your ride height continuously within a tested range, something conventional lowering springs just can’t do.

And if you’re all about that sporty driving experience, you’re in for a treat. With the right adjustments, you can achieve a driving behavior that feels both agile and harmonious, without sacrificing the performance dynamics you love. Plus, every single KW suspension product is rigorously tested—think Nurburgring Nordschleife and KW's 7-post Driving Dynamic Test Center. They don’t mess around when it comes to quality.
