Wilwood Bias Proportioning Valve — Knob Style, M10 x 1

The Wilwood adjustable brake bias proportioning valve allows precise in-cabin adjustment of front-to-rear brake balance by reducing rear brake line pressure. An essential component for track day, motorsport, and competition vehicles where brake bias needs to be tuned to suit different circuits, tyre compounds, or driving conditions. The latest generation forged billet design delivers precise pressure metering in a compact, lightweight package.

Pressure adjustments range from 100–1,000 PSI with a maximum rear line pressure reduction of 57% — the highest reduction available from any proportioning valve. The fine-thread adjuster knob provides smooth, precise tuning without coarse steps.
