Aluminum Brake Proportioning Valve

The labwork 172-2069 is a brake proportioning valve, serving as a replacement for OEM part numbers 15606198 and 172-2069. Constructed from aluminum, it offers mechanical stability and corrosion protection, ensuring long-lasting durability. This component is crucial for vehicle safety, as its function is to balance the pressure transmitted to the front and rear brakes, thereby preventing the rear wheels from locking up during braking. The proportioning valve is installed within the brake system, positioned between the master cylinder and the rest of the brake components, specifically on each axle set. It is designed for compatibility with a range of Chevrolet and GMC C/K series trucks, including 1500, 2500, and 3500 models, with specific fitment years ranging from 1989 to 1996 for various engine configurations. It is important to note that during installation, the air in the valve body and piping must be purged before operation. The product meets or exceeds original equipment manufacturer specifications, and all items are tested for reliability, durability, and performance.
