PerTronix Second Strike Box

PerTronix Second Strike Box

Second Strike is the only ignition system to provide a powerful second spark throughout the entire RPM range.

Other multiple spark discharge systems typically drop off to one spark at about 3000 RPM. Second Strike’s unique crank angle offset (CAO) feature gives you tunability that no other box has.

Simply turn the dial and change the time, in crank angle degrees, that the second spark occurs. A wide range of adjustment (2° to 18°) gives you the flexibility to find the CAO that works best for your engine’s performance and your driving type.

An integrated digital rev limiter protects the engine from over rev conditions.
