Belt Drives Ltd 11mm Belt Drive Kit for 1965-1984 Harley-Davidson Shovelhead Electric Start 4-Speed 47-31SE-4

If you're running a carbureted Shovelhead with an electric starter, a belt drive system eliminates the mechanical complexity of traditional chain drives while delivering smoother power delivery and reduced maintenance. The 11mm belt profile on this Belt Drives Ltd kit provides the load capacity you need for reliable starts and consistent operation, whether you're commuting or putting in seat time at the track. Hard anodized aluminum construction ensures this system handles repeated engagement cycles without compromise.

This is a bolt-on upgrade for 1965–1984 Harley-Davidson Shovelhead models equipped with electric start and 4-speed transmissions. The design features a drilled and tapped front pulley for hassle-free removal during service, and the lightweight architecture reduces rotating mass without sacrificing durability. Note that the inner clutch hub and plates are sold separately, allowing you to customize your setup to match your specific riding demands.
