55-1343 SuperStock ignition module. 103" S&S Shovel

This S&S SuperStock ignition module is engineered for the massive 103 inch S&S Shovelhead engine. As a single-fire unit, it provides a dedicated spark for each cylinder, improving combustion efficiency. It is factory-configured for kick-start use, sparking on the first revolution for reliable starting. The module is pre-programmed with ignition curves specific to the 103 inch displacement, requiring only basic timing setup. For those who prefer electric start, the module can be adjusted by an S&S dealer to include a three-revolution delay, which protects your starter components from kick-back. It is a professional-grade ignition solution for high-displacement Shovelheads.
