Product Details

Wilbers fork fork spring kit, progressive, for Harley Davidson FLHPI Road King Police, Type FL 2, Model Year 09-13 (fork oil must 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. For touring and touring sport, we generally recommend a progressive fork spring to optimise responsiveness and, on the other hand, to increase bottoming-out reserves. Crucially, the combination of the 'Zero Friction' fork springs with the specially developed Wilbers fork oil, as well as observing the correct air chamber for the corresponding vehicle, is very important. If desired, an individual adjustment can be achieved in special cases by changing the air chamber.
For motorsport applications, we recommend the very light linear chrome-silicon fork springs from Wilbers, which were co-developed by the motorsport team.

"ZERO friction" friction reduction through vibratory finishing:
During vibratory finishing, the component to be processed, such as Wilbers fork springs, are located together with a specially adapted abrasive medium in a vibrating container, known as a trough vibrator.
The vibrations of the container generate a relative movement between the workpiece and the abrasive medium, and through constant rubbing against each other, lead to a smoothing of the componentupper. At the end of the process, a fine, glossy surface is achieved.
For Wilbers fork springs, this reduction in surface roughness means a minimisation of friction = ZERO friction.

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

Note: please order the fork oil separately.
