HLS stands for Hydraulic Lift System. KW HLS provides additional road clearance for lowered vehicles. When expanded, a range of up to 45mm of lift is produced, thereby helping sport cars avoid road clearance difficulties such as speed bumps, road construction, etc.

The hydraulic cylinder unit is located on the coilover body between the spring seat and the spring. The advantage of a hydraulic system is that there is no compression of the extended cylinder unit, resulting in no unwanted additional suspension movement while driving.

KW HLS can be activated from inside the vehicle via an LED control switch or by a remote control (optional extra) which eliminates any need for interior wiring. HLS can be activated while driving at up to 80km/h, and maximum lift occurs within 4-5 seconds. KW HLS uses a high quality cylinder unit with durable aluminium construction, and is sealed against corrosion and dirt resistance.

Please Note: This particular kit is an HLS4 kit which can be attached to the front and rear axles, allowing you to lift the entire vehicle. It is a conversion kit specifically for use with existing KW coilovers. It consists of springs, adaptions, hydraulic cylinder and control unit.
