KW H.A.S. 2017+ Audi A4 Quattro / 2018+ Audi A5 Quattro/S5 (B9) AWD w/o Electronic Dampers (48.5mm)

Starting with springs made from high-strength chrome-silicon steel, KW's Height Adjustable Spring (H.A.S.) kit for your 2017-2025 Audi A4 Quattro is designed to work seamlessly with your factory dampers. Unlike conventional lowering springs that lock you into a single ride height, this system allows for precise, millimeter-level adjustments even after installation. This means you can fine-tune the stance of your A4 Quattro to achieve the look you want, while also potentially improving steering response and overall agility.

KW engineers these spring rates specifically for your vehicle's OE suspension dampers and wheel loads, ensuring they pair harmoniously with your factory adaptive or electronic suspension systems. This means all your car's driver assistance systems and comfort features will remain fully operational. The kit also includes vehicle-specific bump stops with dust protection to help guard your factory suspension components against road grime and debris, extending their life. This approach offers a sporty and balanced driving experience without compromising the dynamics that make your performance-oriented Audi so enjoyable.

This kit is a smart alternative to traditional lowering springs, offering the flexibility of a coilover system with the convenience of using your existing shocks. You get a more dynamic appearance and a potentially more responsive feel, all while maintaining the functionality of your car's advanced electronic systems.
