MSD 84335 Details

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.

  • DuPont Rynite material
  • Spark plug-style terminals with improved locking connection
  • Optional wire retainer with caps to lock the wires in place

  • 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

Purchased this cap and rotor to replace the existing MSD parts that have been on the car for 20 years. Still worked fine, just decided to replace during the rebuild. I have been using Speedway for much longer with no complaints.

I just installed this on my Drag car, The only thing that I noticed is you will have to rotate your firing order but other than that it fits. Have not tried it down the track yet!
