KW's H.A.S. or height adjustable coilover system is designed to lower your vehicle while working seamlessly with the original dampers; even when electronic damper control is equipped. The H.A.S. optimizes the performance and steering behavior when electronic damping control is inactive.
Each H.A.S. system is designed specifically for each application with specific spring perches and spring rates. This kit allows for an adjustable lowering solution without the need to purchase a complete coilover kit.
