Product Details

Wilbers fork spring kit, progressive, for Harley Davidson FLHP Road King Police, Type FL 2, Model Year 09-13 (fork oil to be ordered separately), with ABE according to the application list

General Description

Depending on the application, Wilbers offers progressive or linear fork springs, manufactured from the best and highest quality chrome-silicon steel. In touring and touring-sport applications, we generally recommend a progressive fork spring to optimise the response and, on the other hand, increase the bottoming reserves. The combination of the "Zero Friction" fork springs with the specially developed Wilbers fork oil and observing the correct air chamber for the respective vehicle is crucial. If desired, an individual setup can be achieved in special cases by changing the air chamber.
For motorsport applications, we recommend the very lightweight linear chrome-silicon fork springs from Wilbers, which were co-developed with the motorsport team.

"ZERO friction" friction reduction through vibratory finishing:
During vibratory finishing, the component to be processed, such as Wilbers fork springs, are placed together with abrasive media specially designed for this purpose in a vibrating container, known as a trough vibrator.
The vibrations of the container create a relative movement between the workpiece and the abrasive media and lead to a smoothing of the component surface through constant rubbing together. At the end of the process, a fine, shiny surface is achieved.
For Wilbers fork springs, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each fork spring kit includes a recommendation for the viscosity of the fork oil and the air chamber height in the fork. These values have been determined by experienced Wilbers technicians and ensure optimal riding comfort and feedback at the front wheel.

Note: please order the fork oil separately.
