Wilwood brake proportioning valves are adjustable between 100 and 1,000 psi with a twist of a knob or the flip of a lever, and can reduce pressure up to 57 percent. They let you adjust brake bias quickly and easily to compensate for changing track conditions, or for big and little tire combinations.
Wilwood machines each proportioning valve from billet aluminum and gives it a durable anodized finish.
1/8 in. NPT single inlet with 3 x outlet plus brake light pressure switch.
