    Trigger an Accurate EFI Signal!

    Holley Crank Trigger components are manufactured from high quality materials for strength & durability. These systems are designed to provide an engine speed signal specifically to Holley EFI systems only. The crank trigger wheel will provide a very accurate crankshaft speed signal to the ECU. These systems come with the hardware, sensor, and wiring necessary for installation.

    NOTE: It will be necessary to move any engine accessories about 1/8" to accommodate the spacing the trigger wheel adds.
