A customer came into Megatyre Towbars today to inquire about buying a 1 7/8 ths goose neck towball for his European vehicle. I explained to him that all goose neck towballs are available in the 50 mm size only and that the 1 7/8 ths size is not made; that the easiest course of action would be to put a 50 ml coupling on his trailer.
Our customer advised he needed to be able to tow a wide range of borrowed trailers, all of which were 1 7/8 ths. So I advised him I could get his towball reduced to 1 7/8 ths. This process is not cheap.
The price of this service does vary slightly according to the model of vehicle so please contact us directly at Megatyre Towbars, Browns Bay, North Shore, Auckland, for a quote, if you are interested in this service.
