      Warranty Details (90 DAY REPLACEMENT IF DEFECTIVE)

      This is our most popular performance distributor! The 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 In. 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.

      • CNC machined billet aluminum housing and DuPont Rynite base
      • Easy-to-adjust mechanical advance with supplied springs and stop bushings
