6425 MSD 6AL Box Features : The MSD 6AL Ignition Control set the standards that other ignitions strive to reach. In fact, you’ll find ignitions from other companies that carry the 6AL name (and in some cases, the same part number). For 2011, the bar has been raised even higher as we introduce the all new Digital 6AL Ignition Control!
Features

  • With Soft Touch Rev Control
  • Higher output with 530 primary volts and 135mJ of spark energy
  • Efficient components use less current to produce more power
  • Set an rpm limit on the 6AL with two rotary dials
  • Same bolt pattern as the original 6AL with a lower profile housing
  • Built-in LED for system checks
  • All wires exit the same side through a locked, sealed connector
  • Compatible for 4, 6 or 8-cylinder engines

MSD started with a clean slate and drew up plans for an all new housing. We kept the same footprint as the traditional 6AL but lowered the profile for a sleek look. The wiring is all routed out one end of the unit through a sealed and locking connector. This eases installation and keeps your wiring looking neat and clean. The rev limiter was moved right on top of the housing for easy access to the two rotary dials to set the limit in 100 rpm increments.

Inside the Digital 6AL you’ll find a microprocessor that monitors and controls every firing and rev limit. The circuits are updated with efficient components that help the ignition produce more power while drawing less current! In fact, the new Digital 6AL delivers over 530 volts to the coil with up to 135mJ of spark energy for every firing! Increased output combined with MSD’s proven multiple spark series is a win-win situation!

85551 MSD PRO Billet Distributor features:  Chevy V8, Non-Vacuum Advance Pro-Billet Chevrolet V8 This is MSD's most popular performance distributor! The MSD Ignition 85551 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 MSD Ignition 85551shaft 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 MSD Ignition 85551 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.

NOTE: MSD Ignition 85551 Must be used with an MSD 6, 7, 8 or 10 Series Ignition. Supplied with a Cap and Rotor.

31239 MSD 8.5MM Superconductor wire set features: Set includes terminals for engines with early type (socket) and late type (HEI “spark plug top”) distributor caps. 90° boots and terminals factory installed on one end.

Universal Kits
MSD Universal Kits have the spark plug terminal and boot installed with the other end of the wire open. This way, you can route the wires the way you like and cut them for a custom fit! A special Mini-Stripper-Crimper Tool is supplied to strip and crimp the wire together.

The MSD 8.5mm Super Conductor Wire is "The" Performance Wire.
