Sharing the CNC machining techniques with the rest of the MSD distributor line, the Oldsmobile housing is machined from high quality 6061-t6 aluminum. Adding to this strength are two sealed ball bearings that guide the 0.500 inch Shaft accurately through 10,000+ rpm. 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.
