Designed with Sprint cars in mind, the Pro-Mag 12LT is almost 30% lighter than the original Pro-Mag while still producing the same incredible power. Its compact housing sits an inch lower for improved fuel injection clearance and uses a band clamp mount for easier timing adjustments. MSD also designed a dedicated cap and rotor for the 12LT series, injection molded from DuPont Rynite material for high dielectric properties and strength, with a rotor that clamps to the shaft with a retaining bolt assembly.
