HardDrive Black Carbon Tooth 530 Chain Drive Rear Sprocket for 1984-Up Harley-Davidson
The HardDrive Black Carbon Tooth Rear Sprocket is a high-performance hybrid component designed to bridge the gap between lightweight racing gear and heavy-duty street durability. Engineered by Supersprox, this sprocket utilizes a unique dual-material construction: a 7075-T6 aluminum carrier bonded to a high-carbon steel tooth ring. This combination delivers a drivetrain component that is 70% lighter than solid steel while offering a service life up to four times longer than standard aluminum sprockets.
This sprocket is the ideal solution for Harley-Davidson riders performing a 530 chain conversion. By reducing rotating mass and unsprung weight, it allows for faster acceleration and improved suspension response. The black anodized finish on the carrier and black zinc coating on the teeth provide a custom, aggressive look that stands up to the harshest road conditions and high-torque demands of performance V-Twin engines.

Installation and Fitment Notes
For 2000-Present Harley-Davidson models (non-cush drive), this sprocket is a direct fit to the 2.214-inch (2.22) hub center. For 1984-1999 models, the included 1.985-inch (1.9) adapter ring must be used for proper centering. Always install with new Grade 8 hardware and blue thread-locking compound. Verify chain alignment post-installation to ensure maximum component longevity.
