Features

• All-wheel sizes have a 3/4" axle bore and a 3-1/2" hub length. When the spanner bushing is removed, all-wheel sizes can be used on a 1" axle. Please keep in mind, the hub length is the widest point of the wheel, so it is important to ensure you can accommodate this width before purchasing.
• Bolt size: 1/2" (hardware not included).
