Wilwood GM Style Fixed Proportioning Valve with Delay - Part No. 260-11322

Wilwood's GM style proportioning valve is a direct replacement for 1978 and newer General Motors vehicles equipped with front disc / rear drum brakes. Manufactured from high quality aluminum and coated with a durable black anodized finish. Line connections for the valve, if mounted in the OE location, Will allow the original lines to connect directly to the valve. If mounted in a non-OE location, fluid lines may have to be modified. This also does allow usage in other non-GM vehicles. This proportioning valve offers: 63% pressure reduction (rear) after 350 PSI knee point. A 30 PSI delay rear-to-front circuit and circuit failure sender activation at 50 ± 10 PSI. A Recommended maximum operating pressure: 2000 PSI. Non-adjustable front-to-rear proportioning (knee point, rate, etc.) and Anti-dive or metering delay valve: Enables rear brake pressure to build momentarily before front brake pressure builds.

The Wilwood GM Style Fixed Proportioning Valve with Delay (Part No. 260-11322) is designed as a direct replacement for 1978 and newer General Motors vehicles equipped with front disc and rear drum brakes. Crafted from high-quality aluminum and coated with a durable black anodized finish, this valve offers reliable performance and corrosion resistance. The valve’s line connections are compatible with the original equipment (OE) location, allowing for seamless integration with existing brake lines, although modifications may be necessary when installed in non-OE locations. Its versatile design also permits use in other non-GM vehicles, making it a flexible choice for custom applications. This proportioning valve features a 63% pressure reduction after a 350 PSI knee point, helping to optimize brake balance and control during heavy braking scenarios. It includes a 30 PSI delay in the rear-to-front circuit, ensuring rear brakes build pressure slightly before the front, which improves stability and reduces brake lock-up. Additionally, the valve is equipped with a circuit failure sender that activates at approximately 50 PSI, providing an alert system in case of fluid pressure loss. The system is rated for a maximum operating pressure of 2000 PSI, ensuring safety and durability under demanding conditions. This non-adjustable valve maintains consistent front-to-rear proportioning without the need for calibration, offering a simple yet effective solution for brake system enhancement. Its anti-dive or metering delay feature allows the rear brakes to develop pressure first, contributing to vehicle stability during deceleration. Overall, the Wilwood GM Style Fixed Proportioning Valve with Delay enhances brake performance, reliability, and safety for a wide range of automotive applications.
