Get your Mopar fired up with billet accuracy and performance. Remove the MSD cap and Race Rotor and you'll find easy access to the adjustable mechanical advance assembly for easy adjustments. This advance is designed for accuracy and strength with TIG-welded weight pins, nylon pads for smooth movement of the weights and a QPQ coating for friction reduction. Different advance springs and stop bushings are supplied so you can custom tailor a timing curve to fit your Chrysler's needs.
Supporting the advance assembly is a hardened, polished steel shaft. Two ball
bearing guides are used to support the shaft producing incredible stability. Precision paddles of a zinc-plated reluctor pass a maintenance-free magnetic
pickup creating a trigger signal that tells the MSD to fire.
