TC Bros. 48T Rear Sprocket for Chain Driven Harley-Davidson (Converted) 2000-Up

This TC Bros. rear sprocket is designed for Harley-Davidson motorcycles that have been converted from belt to 530 chain at the final drive.

Accepts 530 chain (available separately)
Choice of finish
Durable steel construction
Zero offset
48T sprocket
Used when replacing worn sprocket or a different final drive ratio is desired
Sprocket locks (available separately) recommended for all applications

This sprocket is designed expressly for 2000-and-later wheels with a 2.208" hub hole fitted to Harley-Davidson motorcycles. The 48-tooth sprocket yields a reasonable gear ratio when used at the rear of most Harley-Davidson Big Twin and Sportster when used in conjunction with a suitable sprocket at the transmission. This sprocket's durable steel construction ensures long life and dependable performance. We recommend replacing the front sprocket and drive chain (available separately) at the same time as this rear sprocket to help prevent premature wear.
