Upgrade the front suspension of your Harley-Davidson with the Race Tech FLEK S3580 RT Fork Suspension/Lowering Kit. Designed for improved ride quality, comfort, and handling, this kit helps tailor fork performance to the rider and motorcycle. It is engineered for Harley-Davidson applications requiring 0.80 kg/mm fork springs and provides a practical foundation for refined front-end suspension performance.
The kit includes a matched set of Race Tech Gold Valve Cartridge Emulators, a pair of high-performance fork springs, and lowering hardware. The Gold Valve Cartridge Emulators improve the control and responsiveness of the fork by allowing suspension characteristics to be adjusted more precisely. The spring and emulator combination can be configured to suit rider preference, riding conditions, and the desired balance between comfort and handling.
Included lowering hardware provides the option to lower the motorcycle’s front end by 1 to 2 inches. Lowering is not required for installation and is recommended for show models only, where appearance may take priority over available suspension travel and ground clearance. Professional installation and setup are recommended to ensure correct fitment, alignment, and suspension adjustment. Verify the motorcycle’s specific year, model, fork configuration, and spring requirement before ordering.
