Iron Distributor Gear for MSD Chevy Marine Distributors

This gear means long life, an easy break-in period and reliable performance!
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 engineers have built test fixtures and spent hundreds of hours testing and evaluating the metallurgy of our gears. The result is a special iron alloy gear that is treated to a low-friction coating process.Features:Increased outer hardened layer thickness (RC 55-60)Micro polished surface for smooth contactProprietary formulated ductile ironMelonite QPQ coated reduces friction and initial wearInterstitial carbide concentration improves wear resistance and running properties
