By utilizing a heavy-duty cast iron sleeve and thickened webbing in high-stress areas, it eliminates the flex and catastrophic failures commonly seen in standard clone or Predator blocks.

The built-in front tank mounts also make it versatile for \"stock appearing\" classes.

Producing nearly 10mJ of spark energy—compared to the standard 4–8mJ—this coil guarantees a hotter, more reliable burn for unflinching throttle response.
