This is the Original Boosted 4.0s Crank Trigger designed by @AKAxAuto


36-1 Pattern Trigger Wheel for aftermarket engine management systems, such as the MicroSquirt.

This is a factory replacement damper with the trigger pattern milled directly into it, negating the need to affix and align a bolt on trigger wheel. After machining, the dampers are rebalanced.

Fits AMC/Jeep 4.0L Inline 6 1986-2006

  • 2x 1/4-20 studs
  • 2x 1/4-20 flange nuts

Recommended installation includes relocating two oil pan bolts and studs. Depending on your ECU, a pull-up resistor may be required. This is a resistor that is connected between the sensor power wire and the output signal wire. For installs using a 5V power supply for the sensor, a 1kΩ resistor is required. For a 12V supply, a 2.4kΩ resistor is required. It is important that the sensor ground wire be grounded at the ECU to reduce the risk of interference. An air gap of .060" between the sensor and trigger wheel teeth is recommended.
