Proportioning Valve

The Allstar Performance Proportioning Valve is an essential component for drivers looking to optimize their vehicle's braking performance and safety. Designed primarily for racing applications and high-performance custom builds, this valve allows for the manual adjustment of brake pressure to the rear wheels. By fine-tuning the distribution of hydraulic force, you can prevent dangerous rear-wheel lockup during aggressive deceleration. Whether you are building a dedicated track car or a specialized off-road rig, this component ensures your braking system reacts predictably under various load conditions.

This Allstar Performance Proportioning Valve functions by restricting fluid pressure to the rear brakes, providing a customizable bias that accommodates different tire compounds and track surfaces. The unit features a compact and lightweight design, weighing only 0.42 lbs, which makes it easy to mount in tight engine bays or near the driver’s reach. Its durable construction is engineered to withstand high-pressure hydraulic environments without leaking or losing calibration over time. The intuitive adjustment knob provides tactile feedback, allowing for incremental changes to the braking balance until the desired performance is achieved.

Professional racers and automotive enthusiasts benefit most from the Allstar Performance Proportioning Valve when transitioning between different driving environments or weight distributions. Installation typically involves plumbing the valve into the rear brake line, where it serves as a master control point for the entire system's hydraulic output. This valve is compatible with most standard braking setups and is a staple for those searching to buy professional-grade hardware for their next project. Reviewing your vehicle's specifications will ensure proper fitment within your existing hardline or braided hose configuration.
