Shocker Support:Before you purchase the Shocker Engage board, please check how the stock upper board is connected to the solenoid. In some cases the manufacturer used a solenoid that requires the upper board to be soldered to it, and in such a case you will require specialist tools and equipment for the install.

If you have a CRCB-0045W Humphrey solenoid in your marker, the board is a drop in install.
