1979 Mercury Zephyr Distributor Gears

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. 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. Features 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.

Product Features:

• 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 improves wear resistance/running properties

The distributor is just one piece of this type of ignition system which is typically driven by the engine’s camshaft. The distributor is the device that delivers the ignition spark to the spark plugs at a precise time, and spark timing is critical. Any wear or component out of place in this type of system will result in failure. Within the distributor and mounted to it are many individual pieces which allow the distributor and system to be maintained and repaired to keep it in top working order.

Product Features:

• Application matched component to ensure the system can be returned to like new condition.
• Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
