Crank Triggers

Crank Triggers & Ignition Trigger Systems

Crank triggers provide a precise, reliable ignition timing signal by reading a trigger wheel mounted on the crankshaft balancer. Unlike distributor-based systems that rely on gears and chains with inherent timing variation, a crank trigger eliminates timing scatter for more consistent spark timing — critical for high-RPM, high-boost, and competition engine builds.

OneFastShop carries crank trigger systems including crank trigger kits, trigger wheels, magnetic pickups, crank trigger brackets, replacement sensors, and direct-fit systems for popular engine platforms running aftermarket engine management and standalone ECU systems.

Every crank trigger at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you're setting up ignition on a standalone ECU, replacing a distributor with a crank-fired system, or upgrading timing accuracy on a high-RPM build, OneFastShop has the trigger system.
