    The cap and rotor of any ignition system must be considered mainte­nance items. Just as you change the oil and filter of your car, you should always replace the cap and rotor as a set. To make things easy, we now offer these Cap and Rotor Replacement Kits.

    This MSD Cap (MSD #84335) fits all of the MSD Distributors that use the GM Socket sytle cap (MSD #8437). It will also fit GM Distributors that use a "window" style cap. 

    Cap MSD# 8433:

    • DuPont Rynite material
    • Spark plug-style terminals with improved locking connection
    • Optional wire retainer with caps to lock the wires in place
    • HEI-Type terminals, rather than socket-type
    • Can be used in place of the older design

    Rotor MSD# 8467:

    • Standard on most MSD Pro-Billet Distributors
    • Injection molded from Rynite material for incredible strength and high dielectric properties
    • Stainless steel/brass rotor trip - screwed in place to handle extreme rpm and high heat conditions
    • Deep molded vanes to stir up the air inside the cap to prevent spark ionization
    • Screws are set deep in the housing to prevent spark scatter

            • Built-in stop prevents the adjustment screw from "backing out" like other designs
            • Easy to install
            • Includes 3/32" Allen wrench and easy-to-follow instructions
