Features
Vehicle Compatibility and Return Conditions.
This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.
Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.
Please review the product details and images to ensure it meets your needs. For clarification or assistance, feel free to contact a StreetFX agent. Note: Returns are not accepted for special order or tuning products unless the unit is deemed faulty.
Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase. For assistance or clarification, please contact customer support.

Crank Triggers, Holley EFI, 6.56 in. Diameter, Aluminum, Silver, Adjustable Bracket, Black, 3-wire Pickup, 12-1X, Hall Effect, Ford, Small Block, Kit
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
