The Hallman Pro RX Boost Controller is one of our favorites to use! The RX comes with the lightweight ceramic ball and spring installed for precise boost adjustments in increments of .5 psi and also includes the heavy spring if you are on the higher side of 10-15 psi. Recommended for cars at or just above stock boost levels up to 15 psi. If you decide to upgrade later and want the heavier, steel ball, it is available for purchase separately. The valve is machined out of billet aluminum and stainless steel pieces, available in 6 anodized body colors. The Hallman Pro RX was designed 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. 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.
