I’m ordering a rear receiver today and I can get free shipping if my order is over $150. So I also want to get the receiver extension at the same time. I’ll need it in order to fit a hitch mounted bike rack with the spare tire on the jeep. Below are the links for everything I’m about to get. The bike racks are still up in the air but it will be one of those three (must have the swing out feature and I hope to find a used one.) Everyone has told me I need an extension or I will need to take off the spare tire but no one has told me what size I need. It looks like the smallest option is 8” and after that it goes up to 14” or 18”. I’d rather go as short as possible while still clearing the rear tire. Does anyone know what size receiver extension I need?
