    Holley's Distributorless Ignition System (DIS) components are manufactured from high quality materials for strength & durability. The 58 tooth wheel provides a very accurate crankshaft signal and offers many advantages over a conventional distributor/ignition box including:

  • Improved starting and idle quality
  • More spark energy - especially important when using power adders to maximize horsepower
  • Cleaner Emissions
  • System Longevity - No Moving Parts
  • Tuning Simplicity and Accuracy

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