Hallman Replacement Ceramic Ball for Pro RX MBC

This is a replacement ceramic ball only for a Hallman Boost Controller Pro RX.    This is the ceramic ball that the Pro RX model comes with pre-installed.  [This is not the ball used in the Pro model.]

If you have a functioning Pro RX Hallman MBC, you do not need this.  This is a replacement if for some reason you opened up your Pro RX MBC and the ceramic ball fell out and rolled across the garage and you can not find it.
