This part converts your 2 inch receiver down to a 1 1/4 inch receiver. It adapts for bicycle racks, cargo carriers and possibly ball mounts. Well install this on our two inch receiver hitch and show you how it sits in there. As you can see it sticks out from the hitch which may be an advantage to you have a hitch assist bar back underneath the bumper to give you enough clearance for additional accessories such as a bike rack, cargo carrier or ballmount. Well show you a couple of measurements on this which may be help you determine if you can use to your advantage. Our first measurement will be from pin hole to pin hole which looks like 6 3/4 inches. From this edge of the hitch to the adapter is also 6 3/4 inches. There you have it for part number 80300, the hitch adapter from Hidden Hitch.
