Info

These proportioning valves are similar to what GM used on many cars in the 70s. They are non-adjustable and may require an adjustable valve in the rear brakes (if needed). Block incorporates metering (for front brakes) and proportioning (for rear brakes) into one unit. For use with four-wheel disc brake systems.

Includes hard lines to connect to a master cylinder with 3/8"-24 outlets.
