Most crank triggers have a wheel, with steel studs sticking out, bolted to the harmonic balancer. As the crankshaft turns, the studs pass by a stationary magnetic pick-up, triggering the ignition. This pick-up can be triggered by other bolts, debris, or even vibrations which will cause a loss of power or engine damage. The MSD Flying Magnet Crank Trigger uses four magnets secured in the aluminum trigger wheel that pass by a stationary non-magnetic pick-up to trigger the ignition. This "flying magnet" design produces accurate trigger signals and the non-magnetic pick-up cannot be falsely triggered.
Features:
- Powerful magnets are embedded in a billet aluminum trigger wheel.
- Fits 429/460 Big Block Ford.
- The non-magnetic pickup cannot be false triggered.
- Does not fit Cleveland blocks.
- Absolutely the most accurate way to trigger the ignition.
- Kits feature special brackets and mounting hardware for a variety of engines.
