Wilbert Pogressive front spring set Buell XB12SS 06-08

Wilbers progressive fork springs friction" Friction reduction through fine grinding, resulting in »ZERO friction«.
 

In vibratory finishing, the components to be machined, e.g. components, e.g. our fork springs, together with a specially together with a grinding wheel specially adapted for this in a vibrating container, the so-called trough vibrator.

The vibrations of the container generate a relative movement between the workpiece and the grinding wheel and, due to the constant rubbing against each other, lead to a smoothing of the component surface.
At the end of the processing there is a fine, shiny surface. Particularly with our fork springs, this reduction of the surface roughness means a minimization friction = ZERO friction.

Important is the combination with our specially developed Wilbers fork oil and the observance of the correct air chamber for the corresponding vehicle.

Recommended viscosity and air chamber:

Note:
Fork Oil SAE 7,5 (1 L)
Air Chamber: 120
