KW H.A.S. 2017+ Audi A4/S4 Quattro (B9) AWD w/o Electronic Dampers (50mm)

KW is known for its performance suspension components, and their Height Adjustable Spring (H.A.S.) kits are a smart way to lower your vehicle without sacrificing the ability to fine-tune the ride height. If you're looking to give your 2017-2025 Audi A4 Quattro a more aggressive stance and sharper handling, this H.A.S. kit is designed to work seamlessly with your car's factory suspension, even if it's electronically controlled.

Unlike traditional lowering springs that offer a fixed drop, the KW H.A.S. system uses a special adjustment mechanism that lets you dial in the ride height precisely, corner by corner, even after installation. This means you can achieve the exact look you want and optimize the vehicle's balance. KW uses high-strength chrome-silicon steel for their springs, with rates carefully matched to your Audi's specific damper characteristics and wheel loads. This ensures a sporty yet comfortable ride, maintaining the agility and responsiveness you expect from a performance vehicle. The kit also includes vehicle-specific bump stops and dust protection systems to help keep your factory dampers protected from road debris.

This kit is designed to maintain the full functionality of your Audi's factory electronic suspension systems, so all your driver assistance features and comfort settings will continue to work as intended. It's a well-built solution that offers a significant visual and dynamic improvement over stock, with the added benefit of adjustable ride height.
