Description:

A distributors 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. Model # 8531 Features: Increased outer hardened layer thickness (RC 55-60) Micro polished surffor smooth contact Proprietary formulated ductile iron Melonite QPQ coated reduces friction and initial wear Interstitial carbide concentration improves wear resistance and running properties.
