Holley Ignition Crank Trigger Billet Aluminium Black Anodised Chevy Sm
Holley's EFI crank trigger kits are engineered to provide an accurate crank speed and 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 standard 4-magnet crank trigger systems. Features include: * 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 * 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
