Part Details Vehicle Fitment Reviews
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.
Features:
  • CNC machined billet aluminum housing and billet aluminum base
  • Will not accept a vacuum advance canister
  • Must be used with an MSD Ignition Control
  • Supplied with an HEI style distributor cap and rotor (accepts Cap-A-Dapts)
  • O-ring seals can be added to modified blocks to improve oil pressure control
  • Special oil tract improves lubrication to the distributor and cam gear
  • Nylon pads ensure smooth operation of the advance weights
  • Advance weight pins are staked and tig welded to the plate
  • Mechanical advance assembly can be locked out for crank trigger systems
  • Advance plate and weights are fine blanked from chrome moly steel and QPQ coated for friction reduction
  • Polished steel shaft is QPQ coated and guided by a sealed ball bearing and extra long sintered bushing
