Correct swivel for 2.5″ tongue
Question: I’m looking for a swivel coupler for the tongue of a trailer I’m making to pull behind my motorcycle. The tongue width is 2-1/2″ and the holes, center to center, are 2-1/2″. Which type swivel coupler on your web page will fit? I didn’t find any name of coupler on the original fixed coupler or tongue.
Answer: Those are the same dimensions as the Piggybacker unit on my site. You didn’t say what brand your trailer was but Harbor Freight trailers also use the same setup when the tongue is 2.5″ wide and the center-to-center is 2.5″.
This unit comes with spacers and a new coupler for the front. It has those extra pieces because the swivel units are designed to fit a 2″ square tongue and use a 2″ coupler on the front. The spacers make it fit snug in the tongue and the new coupler allows you to bolt it onto the front with the proper hardware, eliminating the possibility of binding that comes with trying to fit a 2.5″ coupler on the front.
If you happened to have a trailer with a 2.5″ tongue but the center holes were only 2.25″ center-to-center, then that is the same as a “Shelby” coupler. You also need to have the spacers and the coupler. You can just order the Piggybacker unit but put “Size for Shelby coupler” in the comments section and I’ll have it drilled accordingly.
