Product Description

MSD 85551 Pro-Billet Distributor

From the Manufacturer

The housing is machined from a billet of 6061-T6 aluminum on a state-of-the-art CNC machine producing exact tolerances. Modified blocks can also take advantage of the O-ring seals to help maintain proper pressure. 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 pickup mounted in the housing. This high output magnetic pickup is the most accurate way to trigger your ignition. Plus, with no moving parts to wear or adjust, the pickup is maintenance-free. Just above the pickup is MSDs adjustable mechanical advance assembly. Different springs and stop bushings are supplied so you can tune an advance curve to match your application.

MSDs Billet Distributors have been redesigned with many new features, including a race rotor and alkyd cap and a new billet base with full CNC Pro Billet design. The advance assembly is QPQ coated for corrosion resistance.
