Sharing the CNC machining techniques with the rest of the MSD Distributor line, the Olds housing is machined from high quality 6061-T6 aluminium Adding to this strength are two sealed ball bearings that guide the 0.500" 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.
