KW H.A.S. Height Adjustable Spring Kit for 2012-2021 Porsche 911 (991) - 25371043

Fits 2012-2021 Porsche 911 Carrera, Targa, and GTS models (Type 991).

The KW H.A.S. (Height Adjustable Spring) kit provides coilover-style height adjustment while retaining your Porsche's original dampers. Unlike conventional lowering springs that offer a fixed drop, this system allows you to fine-tune the ride height using the KW threaded height adjuster even after installation. This makes it an ideal solution for owners who want a lower center of gravity and a more aggressive stance without sacrificing the functionality of factory electronic suspension systems like PASM.

Every KW H.A.S. kit is engineered specifically for the vehicle’s wheel loads and damper characteristics. The high-strength springs are manufactured from multi-coated chrome-silicon steel to ensure long-term durability and consistent performance. To protect your factory suspension against road debris and bottoming out, the kit includes vehicle-specific elastomer bump stops and a dust protection system.
