Ford 7 1/4" Small Block EFI Crank Trigger Kit 556-115

Holley's EFI Crank Trigger Kit is engineered to provide an accurate crank speed & position signal to Holley EFI systems in the most-demanding, high horsepower, racing applications. Crank position is measured every 10 degrees as opposed to every 45 degrees for a standard 4-Magnet, MSD "style" Crank trigger. It is designed for use on SBF applications using a standard ATI or Fluidamper "style" balancer up to 7-1/4" in diameter.

• 7.25€ diameter, 1/4€ thick, billet steel, 36-1 tooth, crank wheel with Black Zinc Oxide finish for superior corrosion resistance & striking good looks.
• Crank wheel centers off of the balancer€™s hub, eliminating the need for a centering ring
• All billet, 6061-T6 aluminum sensor mounting brackets with €œbright-dipped€ black anodized finish & Laser etched Holley EFI logo
• Custom 3-wire, ferrous-target, Hall-effect sensor with M12X1mm threads for finer gap adjustment
• All Grade 8 & Mil. Spec mounting hardware

Will not work on balancers which do not have a center-hub extrusion (i.e.: Innovators West, etc.).
