MSD Bronze Distributor gears are machined from quality AMPCO 45 aluminum bronze containing 5 percent nickel. This special combination creates high-strength gear teeth that are less prone to wear even with high volume oil pumps. 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 concentration improves wear resistance and running properties.
