701963 Extended Sprocket Shafts & Nuts, Primary Spacers and Transmission Mounting Plates

Custom builders looking to fit wider rubber without offsetting the engine will find these Zodiac extended motor sprocket shafts and spacers indispensable. Designed to fit most Big Twin models from 1970 to present, including Dyna, Softail, Touring, and Trike models, these components allow for offsets ranging from 12mm to 55mm. To protect the crankshaft from the increased leverage of the wider offsets, the 45mm and 55mm spacer rings feature an integrated support bearing. The kit provides the necessary motor sprocket nuts and spacer rings to move the primary drive outboard, clearing the way for fat tires while maintaining proper drivetrain alignment on your custom project.
