Description

MSD8531 by MSD IGNITION
Distributor Gear, 0.500 in Shaft-Iron

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
