The KW Height Adjustable Spring (H.A.S.) kit offers a precise way to lower your vehicle while retaining full factory Electronic Damper Control (EDC). Unlike conventional lowering springs, ride height remains adjustable after installation, allowing you to fine-tune stance and clearance without compromising OEM functionality.
This system is engineered specifically around the factory dampers to improve steering response and overall driving dynamics while maintaining comfort and all driver assistance systems.
