Wilwood adjustable lever-style proportioning valve 100-1000 PSI 1/8-27 NPT WIL260-8420

Brake bias adjustment is critical for extracting maximum performance from your racing setup, and guesswork has no place in your brake system. The Wilwood adjustable proportioning valve gives you six preset positions to dial in the perfect front-to-rear brake balance on the fly, eliminating the need for costly track sessions spent hunting for the right setup. With lever-actuated control and the ability to reduce rear brake pressure up to 57%, this valve lets you optimize stopping power for different track conditions, fuel loads, and tire compounds—all without breaking down your brake lines.
