LEVER STYLE PROPORTIONING VALVES. This proportioning valve has six preset adjustment points actuated by moving a lever allowing racers to adjust brake bias during a race without having to "look" where the knob position is. The lever "clicks" into the six positions for positive adjustment and the bright red lever is easily seen in a busy racing cockpit. Lever can be rotated 180° for easy installation and mounting location. Ideal for oval track, road race, and off road racing where car and racing conditions change throughout the race.
Compact and lightweight forged billet aluminum construction has made Wilwood's proportioning valves the best available. Pressure adjustments range from 100-1000 PSI and provide for a maximum decrease of 57% in line pressure. This adjustment lets you fine tune the front to rear braking balance by proportionately decreasing the rear (or in some cases the front) brake line pressure. Can also be used to adjust individual front wheel braking in dirt track applications.
