55-82 MSD Pro Billet Distributor (Black)
MSD Pro Billet Distributor housing is machined from a billet of 6061-T6 aluminum on a state-of-the-art CNC machine producing exact tolerances. For high rpm stability, a .500" steel shaft is supported by a sealed ball bearing and a long sintered bushing. This shaft also receives a QPQ coating for friction reduction and resistance to corrosion. A precision machined reluctor is attached to the shaft which triggers the magnetic pick-up mounted in the housing. This high output magnetic pick-up is the most accurate way to trigger your ignition. Plus, with no moving parts to wear or adjust, the pick-up is maintenance free! Just above the pick-up is MSD's adjustable mechanical advance assembly. Different springs and stop bushings are supplied so you can tune an advance curve to match your application. Must be used with an MSD 6, 7 or 8-series ignition.

MSD
What do a couple of missile engineers have in common with Corvettes? Well, it was a team of engineers from the White Sands Missile Range who founded MSD in 1970. As they were creating a lean-burn fuel system, they stumbled upon a new type of ignition system which could spark multiple times. Combined with the then-new technology of Capacitive Discharge, MSD found a potent new ignition system for cars. Most efficient when coupled with lean fuels, racers quickly picked up the technology and the legend of MSD was born. No matter whether your Corvette lives on the street or the track, Zip’s collection of MSD Ignition products can help your Corvette perform better and run smoother.
