Overview MSD 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. To you this means long life, an easy break-in period and reliable performance! A distributor's performance is only as good as its drive gear Features Melonite QPQ coated reduces friction and initial wear Micro polished surface for smooth contact Increased outer hardened layer thickness (RC 55-60) Proprietary formulated ductile iron Interstitial carbide concentration improves wear resistance and running properties
