Wilbers fork springs for HD Dyna Superglide Custom FXDC

Product details

Wilbers fork spring kit, progressive, for Harley-Davidson Dyna Superglide Custom FXDC, Type FD 2, model year 06-14 (please order fork oil separately), with ABE according to application list

General description

Depending on the application, Wilbers offers you progressive or linear fork springs, made from the best and highest quality chrome-silicon steel. For touring and touring sport, we generally recommend a progressive fork spring to optimise the response characteristics and, on the other hand, to increase the bottoming resistance. 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 respective vehicle, is very important. If desired, in special cases, individual tuning can be achieved 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 workpieces to be processed, such as Wilbers fork springs, are located together with abrasive media specifically tailored for this purpose in a vibrating container, the so-called trough vibrator.
The vibrations of the container create a relative movement between the workpiece and the abrasive media and, through constant rubbing against each other, lead to a smoothing of the component surface. 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 set includes a recommendation regarding 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 optimum riding comfort and feedback at the handlebar.

Note: please order the fork oil separately.
