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 system does 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.

Each Flying Magnet Crank Reluctor includes a two-piece mounting bracket for the non-magnetic pick-up that in most cases will work on either the passenger side or driver's side of the engine (the SB Chrysler and SB Ford brackets mount on only one side). The CNC-machined aluminum bracket securely holds the pick-up in place and is slotted to provide a wide range of timing adjustment. These systems will reluctor MSD 6, 7 and 8 Series Ignitions and all MSD Timing Accessories.;
