    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.

    8561 is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Works fine, I bought a new distributor from jegs to power up my 383ci SBC and found out that I needed this gear to put on a new distributor to work with my roller camshaft. Wished I had researched a little better, that was an extra expenditure that I was unaware of. Melonized gear should be used on roller cams due to material differences.
