MSD 84101 Extreme Output Rotor GM HEI Distributor

The MSD 84101 Extreme Output Rotor is a high-performance distributor rotor engineered specifically to handle the demands of MSD's high-output HEI ignition systems. Designed as a direct companion to MSD's 20-amp Extreme HEI Module, this rotor is built from custom-molded materials capable of withstanding significantly greater electrical output than a standard stock rotor.

Key Features:

• Engineered to handle the high output of MSD's 20-amp Extreme HEI ignition systems
• Compatible with the MSD HEI Pro-Billet Distributor (PN 8365) as well as most stock GM HEI applications
• Custom-molded construction for superior durability under extreme ignition loads
• Direct-fit replacement — no modifications required for compatible distributors
• Sold individually; also available as part of the MSD HEI Extreme Cap and Rotor Kit (PN 84023)
• Legal for sale and use on emissions-controlled and non-emissions-controlled vehicles (Emission Code 5)
• Backed by MSD's Manufacturer's Limited 1-Year Warranty

The MSD 84101 pairs perfectly with MSD's Extreme Output HEI cap (PN 84111) and is an ideal upgrade or replacement rotor for anyone running an MSD or factory GM HEI distributor with a performance ignition system.
