MSD 8410 GM HEI Replacement Distributor Rotor

The MSD 8410 is a stock replacement distributor rotor designed specifically for GM High Energy Ignition (HEI) style distributors. Built with the same performance-focused standards found across MSD's ignition lineup, this rotor is a direct-fit maintenance replacement that keeps your ignition system firing reliably.

Key Features:

• High-dielectric molded construction — injection molded from Rynite or alkyd material for exceptional strength and resistance to carbon tracking
• Low-resistance brass rotor tip — ensures maximum voltage transfer from the distributor cap to the spark plug terminals with minimal energy loss
• Carbon tracking resistance — voltage-insulating material keeps secondary spark voltage on the intended path for consistent ignition performance
• Direct-fit replacement — installs on stock GM HEI distributors as well as MSD Pro-Billet HEI distributors (including MSD PN 8362)
• High-RPM capable — engineered with performance use in mind, this rotor is standard equipment on most MSD Pro-Billet distributors
• Emissions compliant — legal for use on emissions-controlled vehicles, non-emissions-controlled vehicles, and racing applications

The MSD 8410 rotor is a straightforward, high-quality maintenance item for any GM HEI distributor application. Replacing the rotor at regular service intervals helps maintain strong spark delivery and optimal ignition performance. Backed by MSD's manufacturer's limited one-year warranty.
