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 early model BBC Chevy applications using a standard ATI or Fluidamper "style" balancer up to 7-1/4" in diameter. Features: 8" 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 "bright-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.
