This Hallman Pro RX MBC kit was specifically designed for those that only wish to add a few pounds of boost over stock and have a great amount of control over those few pounds. The kit includes a ceramic ball instead of the 316 stainless ball that comes in our other valves. The ceramic ball only weighs a fraction of what the stainless steel balls weighs. This weight difference allows the ceramic ball to act very quickly as it is constantly changing directions during operation. The ceramic ball in conjunction with the use of the spring will allow very fine adjustment of boost over stock. Boost has been able to be adjusted in half pound increments very consistently with this valve.

This kit includes the ceramic ball, heavy spring, 3 feet of vacuum line, mounting bracket, hardware packet and complete installation instructions all in one kit.

**Available in red, blue, black, gunmetal (not shown), silver, and purple.
