Twisted Choppers Black Aluminum Rear Sprocket and Pulley Spacers for 1984-1999 Harley-Davidson

Twisted Choppers Black Aluminum Rear Sprocket and Pulley Spacers for 1984-1999 Harley-Davidson

Achieve precision driveline alignment with these American-made rear sprocket and pulley spacers. Specifically engineered for Harley-Davidson models running Timken-style tapered roller bearings, these spacers are essential for wide tire conversions or custom wheel offsets. By shifting the sprocket or pulley outward, you ensure proper chain or belt clearance against the tire and frame, preventing premature wear and mechanical interference.

Each spacer is CNC machined with a self-centering registration step. This design ensures the spacer remains perfectly concentric with the wheel hub while providing a matching pilot for the sprocket or pulley to seat against. This dual-sided centering eliminates the vibrations and bolt shearing risks associated with generic, flat spacers. The black anodized finish offers a durable, stealthy appearance that complements any custom build.
