Review on 🚚 CURT 45408 Trailer Hitch Receiver Adapter Reducer Sleeve Set, 3 to 2-1/2 or 2-Inch, 2-Piece: Efficient Hitch Receiver Sleeve for Versatile Towing by Joseph Stone

I was confused by what other reviews were saying about this Super Duty fitting. Since the new F250s are fitted with a 3" hitch, the more common 2.5" hitch requires a female hitch. You only need the inside of this adapter. The exterior is the same as on the truck (so not good). This will allow the inner sleeve to snugly fit the flush insert and align with the coupling pin hole. And it's cheaper than buying a Ford OEM.
