MSD Pro-Billet Distributor

MSD Pro-Billet distributors share the same CNC machining techniques as
the rest of the MSD distributor line. They feature a housing that's
machined from high-quality 6061-T6 aluminum for durability and
show-quality looks. Their oversized shaft receives a QPQ coating for
friction reduction and corrosion resistance, with the added strength of
two sealed ball bearings that guide the shaft accurately at well over
10,000 rpm. An extra-long sintered bushing replaces the ball bearing at
the bottom of Chevrolet models. TIG-welded on top of the polished steel
shaft is MSD's accurate mechanical advance assembly. The weights are
supported by nylon pads that allow the advance to operate smoothly
throughout the rpm range.

For all-out racing, the advance mechanism can also be easily locked
out. To accurately trigger the ignition, a high-output magnetic pickup
is bolted to the base. This pickup produces a precise trigger signal
that will never vary more than one degree at any rpm. A durable gear is
installed for performance applications, and an MSD red cap with brass
terminals and race rotor is supplied.
