Crank Trigger Kit SBC w/Hall Effect Sensor

The MSD Ignition Crank Trigger Kit with Hall Effect Sensor for small block Chevy engines delivers precision ignition timing control essential for high-performance and race applications. This complete crank trigger kit includes a flying magnet trigger wheel, Hall effect pickup, adjustable bracket, and all necessary hardware to retrofit modern electronic ignition to classic and modified small block Chevy engines. Compatible with 7-inch balancers, this system provides the electromagnetic sensing accuracy required for variable ignition curve management and engine tuning optimization.

Hall effect sensor technology offers superior reliability compared to older points-based or magnetic pickup systems, eliminating issues like arcing, contact wear, and inconsistent signal degradation over time. The trigger wheel attaches directly to the harmonic balancer, creating a non-contact magnetic signal that the engine control module reads for precise crank position. This design allows real-time ignition timing adjustment based on RPM, manifold pressure, and other engine parameters—critical for extracting maximum horsepower while maintaining detonation control. The kit's modular bracket design accommodates various small block Chevy mounting configurations with included fasteners.

Engine builders, street rod fabricators, and performance engine shops rely on MSD crank trigger kits when converting carbureted or older distributor-based systems to programmable electronic ignition. Whether tuning a 355 stroker, vintage race engine, or street performance build, this system provides the foundational sensor input needed for modern ignition controllers and engine management systems. The 7-inch balancer compatibility makes installation straightforward on small block platforms from the 265 through 400-cubic-inch displacement range.
