Wilbers Fork Spring - Zero friction - Progressive

Wilbers 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.
