Description

Holley's EFI crank trigger kits provide accurate crank speed and position signals to Holley EFI systems in the most demanding, high-horsepower, racing applications. The crank position is measured every 10 degrees instead of every 45 degrees, like standard 4-magnet crank trigger systems. Holley's EFI crank trigger kits feature 1/4 in. thick, billet steel, 36-1 or 60-2 tooth-crank trigger wheels with black zinc oxide finish for superior corrosion resistance and striking good looks

Other notable features include:

* Crank wheels center off of balancer hubs, eliminating the need for centering rings
* All billet, 6061-T6 aluminum sensor mounting brackets with "bright-dipped" black anodized finish and laser-etched Holley EFI logo
* Custom 3-wire, ferrous-target, Hall-effect sensors with M12 x 1.0mm threads for finer gap adjustment
* Grade 8 and mil-spec mounting hardware
