Distributor Gear – Iron – .500 I.D.

Distributor Gear – Iron – .500 I.D.

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 a 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 and life span
