700929 Inner Primary to Motor Spacer Ring Available in Chrome Plate

These extended motor sprocket shafts and hardware components are designed for custom Harley-Davidson builders looking to install wider rear tires without offsetting the engine. Available in various lengths including 12mm, 25mm, 35mm, 45mm, and 55mm, these extensions allow for proper primary alignment. To manage the increased leverage and load on the crankshaft, the 45mm and 55mm spacer rings feature an integrated support bearing. The kit includes the sprocket shaft, nut, and spacer rings, providing the necessary depth to clear wide rubber while maintaining structural integrity. These components are vital for achieving a balanced, wide-tire conversion on Big Twin models while ensuring the drivetrain remains robust.
