MSD Ignition 8581 - MSD Distributor Gears

Iron Gears
High grade iron and steel replacement gears for MSD distributors. Burnished for a smooth scuff-free finish and are machined from a proprietary, high density material.

Bronze Gears
Machined from quality AMPCO-45 aluminum bronze containing 5% nickel. This special material creates high strength gear teeth that are less prone to wear when used with high volume oil pumps.
