8.425″ LSx Overdrive 12-Magnet Crank Trigger Wheel #1121-12


Billet Aluminum 12-Magnet Crank Trigger Wheel for LSx Chevy.

This large diameter trigger wheel is designed to be bolted onto the front of an Overdrive diameter Innovators West harmonic damper. To be compatible with any other damper, the damper must have a BBC bolt pattern, BBC pulley register and must also be smaller than 8.425″ in order for the wheel to bolt up and the sensor to be able to reach the magnets.

  • Works with Standard 3/4-16 Crank Trigger Sensors
  • 12-Magnet Version
  • Uses High Quality Neodymium Magnets
  • NOTE: This trigger wheel can be converted to a 12-1 (Missing magnet) style trigger wheel by removing one of the magnets. Magnets can be removed with a small press or by using a sharp punch to fracture the magnet and remove the pieces.
