This front pulley offset spacer is ideal for V-Rod wide tire conversions and will allow you to mount a 330 tire on a 12.5 wide rim on the back of your custom V-Rod . We recommend using a support bearing. It provides additional support to the drive shaft with large-sized bearings, so that the shaft is not damaged. Please note with this kit the OEM front pulley must be re-used. Available for all V-Rod and Street Rod models.
