Upgrading to an MSD Flying Magnet Crank Trigger Kit will deliver the precise and reliable signal that a high-performance engine requires. This kit gives you the ability to control timing electronically through a Holley EFI ECU (or other standalone engine management system/ignition controller). At the heart of the kit is the 3-wire Hall-Effect Sensor that is easier to set up, less susceptible to EMI/RFI interference/noise, and less likely to have false signals than other methods (Distributors and VR Magnetic Sensors). In addition, they are less prone to mechanical failure since there are no wear parts. With the included high-quality timing pointer and the use of a direct bolt-on, degreed balancer (ATI 917302 or 918852), you'll be able to adjust timing in the precise increments required for your LS Engine.

On some vehicles, the MSD Crank Trigger Kit may require slight modifications to accommodate special engine plates, pulley systems, etc.

This kit is designed to be used with the ATI Harmonic Balancer 917302 or 918852 but is also compatible with 917264 and 917242. Also compatible with Meziere water pump WP333 and LSX Blocks.

Features:
  • Most accurate way to trigger your electronic fuel injection (EFI)
  • Powerful magnets embedded in a 3/8?? thick billet 6061-T6 aluminum trigger wheel
  • 3-wire Hall-Effect Sensor that is not easily susceptible to EMI/RFI Interference
  • Allows precise indexing by utilizing the 10 degree range on included timing pointer
  • Easy to install much like traditional MSD Crank Trigger Kits (use with ATI Balancer 917302 or 918852 but is also compatible with 917264 and 917242)
  • Rigid mounting that will not flex and cause timing fluctuation

Who is MSD Ignition?

MSD Ignition started back in 1970. Based in El Paso Texas, the company is known for creating quality ignition systems for various automobiles. Today, they are considered the leading company when it comes to the ignition system and has become a brand recognized all over the world.

Changing the Way Vehicles are Made

MSD has helped shape the automotive industry by being the first company in the world to conduct an experiment regarding Multiple Spark Discharge for a vehicle’s ignition system. It has been suggested by Engineers who were working on the White Sands Missile Range in Southern Mexico. They noticed that their quest for power is limited by the amount of spark the ignition system can only generate. Hence, the idea of Multi Spark Discharge.

Racing Application

Soon after the product introduction, racers started applying it to their race cars. Due to its success, other top teams started using MSD which helped paved the way for the brand’s popularity. The majority of the race engines today use MSD and have proven to produce race champions.

The company operates in a 100,000 square feet facility in Texas. They house some of the most state-of-the-art equipment that helps them create products that are superior in quality.
