This is a standard replacement spring only for a Hallman Boost Controller Pro-body MBC.    This is the spring that the Pro model comes with.  The Pro RX comes with this standard spring, as well as Light spring pre-installed in the Pro RX model.  A replacement Light spring is available separately.

If you have a functioning Pro Hallman MBC, you do not need this.  This is a replacement if for some reason you opened up your MBC and the spring launched across the garage and you can not find it.
