The Hallman Pro Boost Controller is one of our favorites to use! Up to 60+ psi, it's been proven again and again to work! The valve is machined out of billet aluminum and stainless steel pieces, available in 6 anodized body colors.

• The Hallman Pro was designed to not require the use of a lock nut or any type or allen wrench to be able to adjust your boost.
• Simply turn the adjustment knob and it stays.
• The adjustment knob cannot be lost or come out of the valve.
• There is not a potential for overboosting since the adjustment knob cannot vibrate loose and come out.
