GZP 35mm Extended crankshaft nut # 40392

For the Custom builder that wants extra fat tires without setting the engine off-center, Zodiac offers 12, 25, 35, 45 and 55mm extended motor sprocket shafts, motor sprocket nuts and spacer rings to fit most Big Twin from 1970 to present. To stop the extra load on the crankshaft due to the 45 and 55mm crank extension, the 45 and 55mm spacer rings come with an installed support bearing. There are also offset transmission plates available for Softail thru 1999.
