Wilwood Six-Position Lever Proportioning Valve with M10 x 1 Bubble-Flare Ports

Six positive lever positions let this valve reduce pressure in an appropriately designed rear brake circuit. Both connections use M10 x 1 bubble-flare seats, distinguishing the metric version from a pipe-thread lever valve that may look similar. Wilwood Engineering began in 1977 under founder Bill Wood and is based in Camarillo, California. The company designs and builds disc brake systems for motorsport, street-performance and specialized applications, with a range extending through calipers, rotors, valves, brake lines, fittings and master cylinders. Individual parts must be compatible with the system in which they operate.
