Innovators West | Small Block Chevy Passenger Side 4-Magnet Crank Trigger Kit
Innovators West Small Block Chevy Passenger Side 4-Magnet Crank Trigger Kit
Part Number: 7006
Add accurate crankshaft position sensing to your Small Block Chevy with the Innovators West Passenger Side 4-Magnet Crank Trigger Kit.
Designed for 6.75" and 7.0" Small Block Chevy harmonic dampers with a flat face and OEM-style 1.245" pulley register, this complete kit provides a clean and reliable way to add crank-trigger ignition control to a performance or race engine.
The system uses the Innovators West #1113 crank trigger wheel fitted with four neodymium magnets, providing precise crankshaft position information for compatible ignition and engine-management systems.
A dedicated #930 passenger-side sensor bracket positions the included Innovators West #964 crank trigger sensor correctly in relation to the trigger wheel. The sensor is supplied with an MSD-compatible wiring plug, making the kit well suited to common motorsport ignition systems.

Why Use a Crank Trigger?
Accurate ignition timing becomes increasingly important as engine speed, cylinder pressure and power increase.
A crank-trigger system reads crankshaft position directly from the harmonic damper rather than relying solely on distributor-driven timing references. This provides a stable and repeatable crank-position signal, helping improve ignition timing accuracy in demanding race applications.
The four-magnet arrangement provides multiple reference points per crankshaft revolution, giving compatible ignition systems a clean and dependable signal.
Important Fitment Notes
The supplied passenger-side bracket is designed around a stock-offset damper configuration.
If the kit is installed with a different Innovators West damper, or with another manufacturer’s damper, the supplied bracket, bolts and/or spacers may require modification to achieve correct sensor positioning and air gap.
Always verify damper diameter, pulley register, pulley pattern and bracket clearance before installation.
Why Choose Innovators West?
Innovators West produces premium harmonic dampers, crank-trigger systems and rotating-assembly components for serious performance and motorsport applications.
Their crank-trigger kits provide an integrated solution using matched trigger wheels, brackets and sensors, reducing the fabrication and setup normally required when building a crank-trigger system from individual components.
