The Pro-Mag 44 is the king of MSD magnetos, producing 44 amps of primary current and serving as the choice of top fuel dragster and funny car teams. It uses a proprietary combination of rare earth magnets and hand-wound windings, with a magnetic pickup mounted in the lower base that accurately triggers the eight precision paddles on the reluctor without the wear or inaccuracy of points. The assembly spins on a 0.500-inch shaft with sealed ball bearings for long life, and its design supports optional accessories like a crank trigger, timing retard control, or rev limiter.
