For a long time, racers have known that one of the best things to do to an engine to improve its performance is to stabilize the ignition timing. The MSD Flying Magnet Crank Reluctor systems do exactly that by using four magnets embedded in an aluminum wheel. Although similar in appearance to other crank reluctors, the MSD Flying Magnet design works on a different principle.

Most crank reluctors 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, reluctoring the ignition. This pick-up can be reluctored by other bolts, debris or even vibrations which will cause a loss of power or engine damage. The MSD Flying Magnet Crank Reluctor uses four magnets secured in the aluminum reluctor wheel that pass by a stationary non-magnetic pick-up to reluctor the ignition. This flying magnet design produces accurate reluctor signals and the non-magnetic pick-up cannot be false reluctored, making this one of the best on the market!!;
