TIG-welded on top of the polished steel shaft is MSD's adjustable mechanical advance assembly. To accurately trigger the ignition, a high-output magnetic pick-up is bolted to the base. This trigger pick-up produces a precise trigger signal. An MSD red cap with brass terminals and Race Rotor are supplied.
