MSD introduced the first aftermarket distributor crafted from a billet of 6061-T6 aluminum. These Pro-Billet Distributors are now available for most popular domestic V8s and several other popular engines. You'll notice that there are several versions of distributors available. There are similarities across the distributor line, such as the upper ball bearing and seal design to guide the QPQ coated shaft or the non-magnetic pickup, but there are several lines available that fit different applications. What ever your need, from Pro- Billet, to the ease of the Ready-to-Run units, or Crank Trigger for more specific applications, and even OEM Upgrades, MSD has your performance distributor.
