Q & A

What's in the Box

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 these 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!

  • 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
