The Hallman Pro Cockpit Controller Add-On Kit contains the cable system that will adapt the Pro and Pro RX Hallman boost controller valves for inside-the-cockpit adjustability. The cable is 72 inches in length. This kit does not contain a boost control valve, that is sold separately. This Add-On Kit is for upgrading your current Hallman Pro or Hallman Pro RX to inside-the-cockpit adjustability.
This system makes it very easy to set initial desired boost level... there is no need to stop the car, pop the hood, adjust the valve, then drive to see what boost level it is set at (and possibly repeating this process several times).
Made in the USA.
