The Hallman Pro kit includes the Hallman Pro valve, which is machined out of billet aluminum and stainless steel pieces. The design of the valve incorporates features not currently available on any other manual boost controller.
Hallman has designed the Pro valve to not require the use of a lock nut or any type or allen wrench(s) to be able to adjust your boost. Simply turn the adjustment knob and it stays. Another great feature is the fact that the adjustment knob cannot be lost or come out of the valve. Simply put there is not a potential for overboosting since the adjustment knob cannot vibrate loose and come out.
The Pro kit also includes: 3 feet of vacuum line, mounting bracket, hardware packet and complete installation instructions all in one kit. This kit has all the installation hardware that is needed for most all turbo installs. Plus, it comes with a mounting clamp to hold the valve.
