Overview 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. To you this means long life, an easy break-in period and reliable performance! For use on Ford 289 and 302 Features Interstitial carbide concentration improves wear resistance and running properties Proprietary formulated ductile iron Melonite QPQ coated reduces friction and initial wear Micro polished surface for smooth contact Increased outer hardened layer thickness (RC 55-60)
