Adjustable Proportioning Valve w/ Distribution Block Option

Adjustable Rear-Brake Bias Proportioning Solutions We offer two layout options so you can choose the assembly that best suits your build and brake-plumbing configuration. Option A – Basic Proportioning Valve Layout An aluminum-bodied, knob-adjustable proportioning valve that allows you to fine-tune rear-brake pressure and optimize front-to-rear braking bias. It accepts both 3⁄16″ and 1⁄4″ brake-line fittings and can be mounted in a convenient location near your master cylinder or under-hood plumbing. Built with brass internals, anodized for corrosion resistance.  Option B – Combined Distribution Block & Proportioning Valve Layout Includes everything from Option A with the added benefit of an integrated distribution block: one unit that mounts near the master cylinder to distribute brake fluid to all four wheel circuits, while the built-in proportioning valve lets you control rear bias. This layout simplifies plumbing, reduces leak points and integrates the brake-light switch provision.
