Crank Trigger Kit SBC w/Hall Effect Sensor

The MSD Ignition Crank Trigger Kit with Hall Effect Sensor for small-block Chevrolet engines is a precision ignition trigger system designed for engine builders and tuners who demand accurate spark timing control. This kit replaces traditional mechanical distributor pickups with modern Hall Effect sensor technology, providing reliable RPM signal generation regardless of engine speed, fuel octane, or atmospheric conditions.

The Hall Effect sensor technology offers superior reliability over mechanical point-based ignition by using a solid-state switch triggered by a rotating magnet on the crankshaft. This design eliminates point erosion, pitting, and the contact bounce that degrades spark quality in traditional systems. The MSD Crank Trigger Kit mounts directly to your small-block Chevrolet crank and interfaces with MSD's proven ignition controllers, providing instantaneous RPM sensing and allowing programmable timing curves tailored to your engine's fuel type, compression ratio, and intended use.

This trigger system is ideal for engine builders upgrading carbureted small-block Chevrolets to electronic spark control, whether for street engines, bracket racers, or high-horsepower cruisers. The compact footprint and verified weight of 2.9 lbs minimize installation complexity while maintaining maximum reliability in high-vibration environments.
