    The Pro Mag 12 is Clock-Wise Rotation. MSD took their original Pro Mag 12 distributors, added some new features to build performance, and subtracted 3 lbs. to help you get down the track faster. The results are the Pro Mag Lites.

    They utilize a magnetic pickup design with 16 rare earth magnets for rock-steady performance without recharging. They deliver 12 amps and 40,000 V worth of spark energy, feature built-in rev control that's good for up to 12,000 rpm, and use an all-billet housing for superior durability. They're compatible with MSD's crank trigger system. 

    Each generator features an adjustable slip collar that provides easy adjustment of the magneto and cam gear alignment. This is critical for engines with varying deck heights, custom heads and modified intakes.
