Pro-Billet Small Diameter
This Distributor was designed for racers and street rodders that have space limitations due to firewall interference, large air cleaners or oversize intake manifolds such as tunnel rams.
Like all MSD Pro-Billet Distributors, this housing is constructed on a CNC-machine from 6061-T6 aluminum. Proven performance features include a high output magnetic pickup and precision machined reluctor for accurate ignition triggering. A fully adjustable mechanical advance allows you to tailor the advance curve to your specific application. A full selection of springs and bushings are supplied with each distributor.
For high rpm reliability, the steel shaft is QPQ coated and is supported with a ball bearing at the top and a sintered steel bushing at the bottom. The QPQ coating reduces friction and allows much higher rpm ranges and longevity over conventional bronze bushing/steel shaft combinations.

NOTE: Must be used with an MSD 6, 7, 8 or 10 Ignition. Supplied with a Cap and Rotor.
