Wilbers Fork Spring - Zero friction - Progressive PD Valve and sliding behavior compared withWilbers progressive fork springs ZERO Friction finishing Our vibratory finishing process (trough vibrator with tailored media) micro polishes the spring surface. The resulting fine, shiny finish reduces surface roughness and friction hence ZERO Friction. Pair with our specially formulated Wilbers fork oil and the specified air chamber for your vehicle to maximize performance. Product may differ from the picture. Recommended viscosity and air chamber:
