The Pro-Mag ignition boxes by MSD are designed to be reliable in delivering full energy sparks throughout the entire rpm range of an engine. This component utilizes Field Effect Transistor or FET technology for better efficiency than traditional magnetos that use points as a trigger source. FETs are more accurate, durable, and capable of handling more current than conventional magnetos that falter at high rpm.

The Pro Mag allows each spark to glow for up to 26 degrees of crankshaft rotation and they also let you plug in an MSD two or three-step module selector to establish multiple rpm limits during warm-up laps or for consistent hole shots. What's more, the Pro-Mag also has a built-in soft touch rev control. The rpm limit is appropriately adjusted with plug-in modules and would reliably safeguard the engine in case of a driveline failure or missed shift.

Established in 1970, MSD is a highly-regarded developer and manufacturers of top-quality ignition controls, distributors, ignition coils, and other essential accessories that aim to optimize the functionality of an ignition system.
