- Wilwood GM OE Style Proportioning Valve
The Wilwood GM OE Style Proportioning is a direct replacement for 1978 and newer General Motors vehicles equipped with front disc/rear drum brakes. Like all Wilwood products it is manufactured using high quality aluminum that is coated with a durable black anodized finish. When mounted in the OE location the line connections are designed to allow the original lines to connect directly to the valve. If mounted in a location other than stock the fluid lines will have to be modified to make connection. This also allows usage in other non-GM vehicles.
