OVERSEAS CUSTOMERS PLEASE NOTE.:  When ordering bogies you need to order them individually so as Australia post can calculate the the correct amount. This is  as a pair ( 2 off)  exceeds their boxed weight restrictions of 20kg  So if you need 2 bogies please make 2 singular transactions.  Freight costs remain the same as it is all determined by shipment weight. For AUSTRALIAN ORDERS multiple bogies of any number can be selected but using ( pick up at factory ) option and we will send a quote for the freight to either your door or local depot . Thank you for your understanding.
