Compact and lightweight forged billet aluminum construction has made 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 brake line pressure.
A proportioning valve is usually required when upgrading to rear disc brakes or larger front brakes
Note! Adjustable brake bias valves are required by traffic authorities to be mounted in such a position as to not be adjusted from the driving position.The above is not applicable to race or registered rally cars.
