A distributor’s performance is only as good as its drive gear. MSD Ignition has put a great deal of effort into researching and testing a variety of metallurgical compositions, heat treating and coatings to provide you with a durable, accurate and strong distributor gear. MSD Ignition, engineers have built test fixtures and spent hundreds of hours testing and evaluating the metallurgy of MSD Ignition's gears. The result is a special alloy iron gear that is treated to a low friction coating process. To you this means long life, an easy break-in period and reliable performance!
MSD Bronze Distributor gears are machined from quality AMPCO 45 aluminum bronze containing 5% nickel. This special combination creates high strength gear teeth that are less prone to wear even with high volume oil pumps.
