Features to know about

Black Powder Coating vs. Galvanized Steel

When choosing the finish of your trailer parts, it's not a matter of which is better, but rather which is better for your application. You want protection, but you also want it to look good and hold up in the environments you're boating in. If you have a freshwater setup, black powder coating will give you a nice finish that will protect the parts from everyday wear, scratches, and chipping. If you have a saltwater setup or plan to boat in brackish water, you'll want to go with the galvanized steel. Galvanized steel is hot-dipped in zinc. The process bonds the zinc to the steel and gives it a layer of protection that guards against rust, even if it gets scratched.

Video Transcript for Review of Swing King Folding Trailer Tongue - Coupler Hinge Kit - TD33FR

Hi everyone. Steve here with etrailer.com. Let's take a look at our swing king bolt-on swing tongue kit. It's gonna fit a three by four inch straight tongue trailer and it has a nice black powder coat finish. So folks, the swing tongue kit will allow you to convert any regular straight tongue into a swing tongue, giving you extra convenience of space and versatility. So by simply pulling a pin once it's installed, you'll be able to pivot this at least 90 degrees, if not farther, all the way around as tight as you can next to itself, giving you maximized storage space in your area.

Maybe it's parking it inside of a garage and fitting it in there and those kind of things. But again, most small trailers, boat trailers, maybe Ski-Doo trailers, those kind of things, jet skis, rather, and those kind of trailers that have those straight tongues or even a small yard trailer and those kind of things, this will work great on. And you do get all the necessary bolts hardware for installation. Overall, I got 20 and one quarter inches long, four and five eighth inches tall. And the widest part was right here in the center at six inches.

Now this is just loosely pushed together right now as you can see, you have the open channel on the bottom, that's where that three by four inch measurement comes into place as far as your trailer tongue. And then once you would have this installed and you pulled the pin, you'd be able to then pivot this left or right. Now, obviously because it's brand new and I got it jammed in here without the pins, it's not gonna cooperate with me. There we go. So, okay, so like I said, once you get this installed and you have the pin in there, it's gonna pivot just fine.

And like I said before, it can pivot all the way back pretty much right upon itself once you get everything installed. So again, two pieces, it's gonna come like that. And then of course you have that open end for your trailer tongue to slide into, giving you maximum strength and durability once you've installed the bolts and stuff. Folks, that will wrap it up for our quick look together. I'm Steven, thanks for watching and if you have any questions, reach out to us.

We're here to help you.

These are great for tight garage space, make shure you have really good drill bits, 181/2” holes , you also need a decent sayzall with metal tooth blade. I used a t square to make my cut lines with a paint pen .
Very carefully cut top corners, then across top, cut each side with minimal penetration, you have wires inside, bend tongue downward lift wires with coat hanger etc , make Final Cut under wires. Paint for rust protection

I love when our neighbors (customers) think outside the box Todd! Great way to get it extended without the need of adapters that can cut the towing weight down, I'm going to keep this idea in my back pocket. Thanks for including the picture as well, install looks fantastic!

I have been trying to order a swing hitch through companies in canada to no sucsess either they are discontinued or they send the wrong product saying thats what i ordered.
I then reached out to etrailer and they had what i was looking for and processed my order , i recieved my order on time as said i would. Yes its what i wanted and ordered, i wont install till fall but i am happy with the product and the service i recieved. Would i recomend etrailer, most definitely.

Thanks Ian!

Heavy duty, nice quality. Good customer service, communication and tracking of shipment.

Install was pretty straight forward. There is some vertical play when the bolt and pin is installed. Is this normal or does a washer need to be added?

A little bit of play is normal, but you can certainly install a washer to take some of that up if you wish.

Part is as depicted, actually better than I was expecting. Shipping was fast. Price was good.

Excellent WEB-SITE.

Great product. I had to grind out and chisel a few welds and weld slag that did not allow the tung to fit into the collar properly, but it was not a big deal - only because I had to tools to clean it up. Is 50 pounds of torque proper for the bolts? Seams like it keeps bending the tube.

  • Replacing TDE 70LP On Swing Away Tongue
    Hi Jeong-Won; the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX89FR fits a 3" wide trailer tongue without a specific height requirement. To add a hinge back onto the tongue you simply have to measure the height. If you have a 3" x 4" trailer tongue you can use the SwingKing # TD53FR (galvanized) or # TD33FR (black powder coat). If you have a 3" x 5" tongue then # TD93FR (galvanized) or # TD43FR (black). If that was the old integrated design I would expect to have to buy some...
