Crank Trigger Kit SBF w/Hall Effect Sensor

The MSD IGNITION Crank Trigger Kit SBF with Hall Effect Sensor (Part #86401) is a complete ignition trigger system engineered for small block Ford engines requiring modern spark timing control. This kit combines a flying magnet trigger wheel, Hall effect pickup, mounting bracket, and all necessary hardware to convert mechanical ignition into a reliable, adjustable electronic system optimized for carbureted and EFI applications.

The 6.562-inch balancer-compatible trigger wheel integrates directly with SBF crankshaft balancers, eliminating the need for costly custom fabrication. Hall effect sensor technology provides precise crank position sensing without wear-inducing magnetic drift, delivering consistent trigger signals across a wide RPM range. MSD IGNITION's engineering ensures accurate signal acquisition for use with modern ignition controllers, allowing fine-tuned spark advance curves impossible with points-and-condenser systems. The complete kit includes pickup assembly, trigger wheel, mounting hardware, and bracket for straightforward bolt-on installation.

This system addresses the needs of engine builders, hot rod enthusiasts, and restomod fabricators who require electronic spark timing without replacing factory balancers or machine work. Whether upgrading a vintage carbureted small block for reliable cold-weather starting or preparing a fuel-injected build for precision engine management, the Hall effect trigger kit delivers the foundation for advanced ignition control. Weighing 2.8 pounds and compact enough for tight engine compartments, this kit integrates seamlessly into existing SBF installations.
