however, modern fuel injection systems and sophisticated testing equipment have exposed inadequacies in traditional crank trigger designs. To correct for timing fluctuations in high-RPM racing applications, FAST engineers replaced the fluctuation prone 2-Wire Inductive Pick-Up with a modern digital Hall-Effect design. This digital Hall-Effect Pickup, coupled with Samarium cobalt magnets installed in the trigger wheel, result in crank rotation measurements that are accurate to of a degree from 0 to 13,000 engine RPM. The FAST Magnet Crank Trigger Kit's digital Hall-Effect Pickup is far less susceptible to electromagnetic noise interference than competitors' antiquated 2-wire designs. Additionally, the Digital Hall-Effect Pick-Up's accuracy is unaffected by electrical system voltage variations: maintaining -degree timing accuracy from 7 Volts to 30 Volts DC. Despite its advanced design, the FAST Magnet Crank Trigger maintains compatibility with other brands' ignition systems. Outputting a clean square-wave signal, the Magnet Crank Trigger can trigger ignition boxes directly or integrate with EFI systems such as the FAST EZ-EFI 2.0, XFI Sportsman and XFI 2.0. An integral LED eases timing calibration and diagnostics. The FAST Magnet Crank Trigger Kit does not sacrifice durability for technological innovation. Crafted from billet aluminum then black anodized, the trigger wheel and pickup brackets will withstand harsh racing environments. OEM quality braided wire wrap protects the pick-up pigtail, while a weatherproof Deutsch connector terminates the harness.

Crank Trigger, Magnetic, for use with 8 in. Balancer, Chevy, Big Block, Kit
FAST magnetic crank trigger kits are setting the new industry standard for timing accuracy while preserving compatibility with other brands' ignition systems. Crank triggers are known to provide the most accurate crankshaft rotation measurement; however, modern fuel injection systems and sophisticated testing equipment have exposed inadequacies in traditional crank trigger designs.
To correct for timing fluctuations in high-rpm racing applications, FAST engineers replaced the fluctuation prone 2-wire inductive pick-up with a modern digital hall-effect design. This digital hall-effect pick-up, coupled with samarium cobalt magnets installed in the trigger wheel, result in crank rotation measurements that are accurate to a quarter of a degree from zero to 13,000 engine rpm.
These pickups are far less susceptible to electromagnetic noise interference than 2-wire designs. Additionally, the pick-up accuracy is unaffected by electrical system voltage variations—maintaining quarter-degree timing accuracy from 7 V to 30 V DC. Outputting a clean square-wave signal, FAST magnetic crank trigger kits can trigger ignition boxes directly or integrate with EFI systems such as the FAST EZ-EFI 2.0, XFI Sportsman, and XFI 2.0. An integral LED eases timing calibration and diagnostics.
These kits don't sacrifice durability for technological innovation. Crafted from billet aluminum then black anodized, the trigger wheels and pick-up brackets will withstand harsh racing environments. OEM-quality braided wire wrap protects the pick-up pigtail, while a weatherproof Deutsch connector terminates the harness. Order the kit recommended for your year, make, and engine application.
