Description

For Small Block Chevrolet3-wire Hall Effect SensorScrew in type for easier installationLess susceptible to EMI/RFI interference/noiseIncluded are bracket, mounting hardware, and hall-effect sensorThese systems are designed to provide an engine speed and position signal to most EFI systems, with control being enabled by the ECU (not included). The kitâ??s 3/8â?, 11, or 12 magnet wheel will provide an accurate crankshaft speed and position signal to the ECU in the most-demanding of racing applications. These kits were designed specifically for use on early model Small Block Chevy applications equipped with a standard, aftermarket ATI Super Damper or Fluidampr â??styleâ? harmonic balancer. The 7â? trigger wheel included with these kits was designed to center off of the hub of the balancer and therefore, does not require a centering ring for wheel centering. Consequently, these kits will not work on balancers which do not have a center-hub extrusion (i.e.: Innovators West, etc.). In addition, these wheels will only work with balancers having a 3-hole, wheel mounting bolt-pattern. On some vehicles the Crank Trigger Kit May require slight modifications to accommodate special engine plates, pulley system, etc.
