Current stock: 0

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.


  • Increased outer hardened layer thickness (RC 55-60)

  • Micro polished surface for smooth contact

  • Proprietary formulated ductile iron

  • Melonite QPQ coated reduces friction and initial wear

  • Interstitial carbide concentration improves wear resistance and running properties
