MSD Pro-Billet Chevrolet Distributor

MSD 85551 MSD Pro-Billet distributor.

Designed for Chevrolet small block and big block engines.

MSD's most popular performance Chevy 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" 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.

Supplied with cap and rotor.

NOTE: This distributor must be used with an MSD 6A or 6AL Ignition shown below.

Designed for use with the MSD 85551 distributor shown above.

Custom cut for Chevy SMALL BLOCK engines and pre-assembled, ready to install.

The MSD Super Conductor is the ultimate performance wire!

It's extremely low resistance combined with the ability to suppress Electro Magnetic interference is a combination that defies the common laws of physics.

Less resistance means more energy is going to make it to the spark plugs to ignite the air/fuel mixture.

Helically wound copper alloy conductor core features Dupont Kevlar material for increased tensile strength.

Copper alloy conductor has a resistance value of less than 50 ohms per foot of wire! This ensures that the most energy possible makes it to the plugs.

Ferro-magnetic impregnated center core creates and effective EMI choke.

Forty feet of conductor is wound into a single foot of wire to high EMI Suppression.

8.5mm jacket.

Red in color with grey boots.

Extra heavy glass braid.

High dielectric insulator.

MSD Dual Crimp Terminals have large crimp tabs to grip the sleeve with separate crimp tabs for the conductor.

Snap lock spark plug grip.

The best spark plug wire your money can buy!
