AMAZON.CA PRODUCT DESCRIPTION MSD's Pro-Billet distributor feature a housing that is machined form high quality 6061-T6 aluminum for durability and show-quality look. The magnetic style trigger, mechanical advance and iron gear insures reliability. MSD Ignition warrants its products to be free from defects in material and workmanship under normal use, if properly installed, for a period of one year from the date of purchase. 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 MSD's adjustable mechanical advance assembly. Different springs and stop bushings are supplied so you can tune an advance curve to match your application. MSD's 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. FEATURES * for Chevy V-8 * C.A.R.B. Approved: E.O.
