Wilwood 260-11179 Adjustable Combination Proportioning Valve Knob 3/8-24 IF

The Wilwood 260-11179 Combination Proportioning Valve is designed to simplify brake system plumbing and proportioning adjustments in compatible custom brake systems. Its knob-style adjustable proportioning valve allows rear-circuit pressure adjustment while the combination block maintains full isolation between the front and rear fluid circuits.

The valve can be used with compatible tandem outlet or dual-mount master cylinder assemblies. The rear circuit uses one inlet and one outlet through the adjustable proportioning valve, while the front circuit uses one inlet with two outlets for flexible brake-line routing.

Vehicle Fitment
