MSD-81392 - MSD PROMAG 20 CW CHEVY ADJ BASE (1pc)

The 81392 is Clock-Wise Rotation. The increased output of the 20 Amp Pro-Mag was born of racers being racers; always asking for more power. This stemmed from drag racers that were using a 12 Amp system, but just didn�t require a 44 Amp system. The engineers at MSD found that with a few changes to the internals of the generator it would deliver the increased current through the same Electronic Points Box, p/n 8106.
