520115 Transmission sprocket, 22t

This 22-tooth transmission sprocket is designed for the early 5-speed Big Twin models, specifically covering the 1979 to 1985 year range. As a direct replacement for OEM 33336-83, this MCS part ensures your drivetrain remains reliable and efficient. The 22-tooth configuration is a standard setup that balances acceleration and top-end speed for the Shovelhead and early Evolution era 5-speed gearboxes. In the workshop, we always check these for wear whenever the primary is open; a fresh sprocket helps extend the life of your drive chain and prevents unnecessary vibration. It is a straightforward, heavy-duty component built to meet or exceed original factory standards.
