MSD Distributors

MSD Billet and Pro-Billet are the finest performance and racing distributors available. Every feature is designed to provide the best in performance and endurance to top off your ignition system.

Billet Housing

Like the multiple spark, CD ignition, MSD was the first to introduce a distributor housing machined from a billet of aluminum. MSD uses state-of-the-art Computerized Numerical Controlled (CNC) mills and lathes to create each housing. This procedure produces a flawless, lightweight distributor housing that is accurate to within 0.001".

Shaft and Ball Bearing Guide

The complete line of MSD Distributors uses a polished steel shaft that receives a QPQ, or Tuftride coating. This process produces a durable finish that reduces friction and resists corrosion. To accurately guide this shaft, MSD uses a sealed ball bearing located at the top of the housing. At the bottom of the housing, an extra long sintered bushing controls the shaft. This combination keeps the shaft spinning smooth and accurately throughout 10,000+ rpm.

Magnetic Pickup

All of the MSD Distributors (except crank trigger models) use a high output magnetic pickup to trigger the ignition system . This pickup is completely maintenance-free requiring no adjustment ever. The pickup is mounted to the base of the distributor housing and plugs directly into your MSD Ignition Control. A trigger signal is created as a precision made reluctor (attached to the shaft) passes by. The reluctor has a "paddle" for each cylinder and when the paddle passes the pickup, a signal is created.

Adjustable Mechanical Advance

One of the most important features of the MSD Distributors is the adjustable mechanical advance assembly. The advance assembly allows you to accurately modify the advance curve to match your specific application. To start with, the advance plate is stamped and machined from chrome moly . Weight pins are then staked in and tig welded in place. This assembly, along with the weights, then receive a corrosion resistant QPQ coating. Nylon weight pads are installed under the weights to ensure smooth movement as the weights are pushed out from centrifugal force to advance the timing. The advance assembly is mounted on top of every MSD Distributor making adjustments a breeze. A variety of advance springs and stop bushings are supplied with each distributor giving you the ability to set up to 24 different curves.

CARB Approved Distributors

MSD offers distributors that have been approved by CARB for use in all the

Pro-Billet Chevrolet

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. 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.

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

Digital E-Curve Pro-Billet

The all new Digital E-Curve Distributor will drop right in your engine and fire up with three simple connections! Not only are there no external controls or boxes to mount and connect, but you can set a timing curve with the twist of a rotary dial! That s right, no more springs or stop bushings to fumble with. A new digital module lets you select from 20 different centrifugal curves and five vacuum curves - that s 100 combinations! Simply remove the cap to access the rotary dials and select a curve to match your application. You can also set an rpm limit that will protect your engine from overrev damage caused by a missed shift or driveline failure. This limit is adjustable from 5,000-10,000 rpm. These adjustments are possible due to an advanced digitally controlled ignition module. Not only does this module offer these adjustable options, it also produces a hearty jolt of energy to the coil to produce a powerful spark that will fire up your engine s performance. Also, a magnetic pickup is used for reliable and accurate trigger signals throughout the entire rpm range of your engine. The E-Curve Distributor is topped with MSD s Rynite molded cap and rotor and is supplied with a heavy duty gear and a matching 3-pin Weathertight wiring harness.
