About This Product
This MCS rear sprocket features 49 teeth and a durable black finish, making it an excellent replacement for worn-out drivetrain components. It is engineered to fit 1973 to 1985 4-speed Big Twin models and 1979 to 1981 Sportsters. Stepping up to a 49-tooth count can help with low-end acceleration, depending on your front sprocket setup. As any mechanic knows, a fresh sprocket is the best way to ensure your drive chain tracks straight and lasts as long as possible. This part, identified as number 903243, offers a perfect balance of classic fitment and modern manufacturing standards for your vintage Harley.
Manufacturer part number: 903243.
