Wilwood Proportioning Valve - GM Style Fixed w/ Delay (Metering Valve)

This Wilwood proportioning valve features a 30 PSI delay in the rear-to-front circuit, meaning rear brake pressure builds momentarily before the front brakes engage. This is a direct replacement for 1978 and newer General Motors vehicles that use front disc and rear drum brakes. The valve is manufactured from aluminum and finished with a black anodized coating for durability. If you're mounting it in the original equipment location, your factory brake lines should connect directly. If you choose a different spot, you might need to modify the lines.

This valve offers a fixed 63% pressure reduction to the rear brakes after a 350 PSI knee point, and it activates a circuit failure sender at 50 ± 10 PSI. The maximum operating pressure is 2000 PSI. It's designed to provide a specific pressure curve without adjustability for the front-to-rear proportioning, knee point, or rate, acting as a metering valve to help balance your braking system.
