Within the compact layout of a Sprint car, minimizing weight and maximizing clearance are critical to overall performance. Ignition components must provide strong, consistent output while fitting into tightly packaged engine bays often shared with mechanical fuel injection hardware. The MSD Pro Mag 12LT Generator was developed specifically to meet these space and weight requirements without compromising spark performance.
This model is approximately 30 percent lighter than the original Pro Mag yet maintains comparable output capability. Its redesigned housing positions the unit one inch lower, improving clearance around intake and injection components. A band-clamp mounting system allows for quicker installation and more precise timing adjustments at the track.
For the 12LT series, MSD created a dedicated cap and rotor assembly. The distributor cap is injection molded from DuPont Rynite material, chosen for its high dielectric strength and durability under racing conditions. The matching rotor, also constructed from Rynite, is secured to the shaft with a bolt-retained assembly to enhance reliability at high engine speeds. This 12LT Generator is not convertible to a 20 Amp Pro Mag configuration. Offered in black or red finishes.
Designed for competitive motorsports use, the Pro Mag 12LT Generator combines reduced weight, compact packaging, and dependable spark energy for demanding race environments. Backed by a 1-Year Warranty.
