Speaker 1: Today we're taking a look at a repair kit for Fulton A-Frame Couplers. Now this repair kit has any replacement part you may need to repair your coupler, excluding the coupler housing. Repair kits are great because it saves you from having to replace the entire coupler. You can use all the new pieces, or just pick out what needs to be replaced. It works with coupler part numbers F44305R0317 and F44305R0500. This kit is designed for couplers that use a two and five-sixteenth inch ball and have a capacity of 10,000 pounds.

It comes with detailed installation instructions to help walk you through your whole repair step-by-step. And this repair kit includes a brand new lever.And I do want to point out that all the components are made from steel. And they do feature protective finishing to keep them safe from rust and corrosion. But you do get a new lever with the trigger style latch. Also, you get the new groove pin and link pin.

You also get the new spring and the new ball clamp, which threads onto the end of the link pin. And then with the kit, you also get a new cap screw and nylon locknut.That's going to do it for today's look at the repair kit for Fulton A-Frame Couplers.

Great customer service. Above and beyond. Thank you.


E-trailer had the part that no one else had in stock ! I needed the part for my customers trailer so his go-kart team could make the race this weekend. I got the part on time, when I needed it.

Superb customer service from Andrea. Very pleased !!!



Great, still working fine. Quality product!!


The coupler broke on my 20' 2007 Pace enclosed car trailer and when I called Pace I was told they went bankrupt in 2011 and were recently bought out. The new owners didn't know what brand the A-frame hitch was and it didn't have any markings/labels. I bought this kit after researching for hours online and it is the EXACT kit I needed! Great quality and price, thanks!


Trailer locking hitch broke, making it unable to be towed. I called and was able to get the Fulton lock hitch over nighted. I was able to repair hitch in about 20 minutes . great product and service. This is the second time I have used etrailer with great success.


Why did I wait so long.... I do not know how many juryrigged bearings I made to temporarily fix the hitch. I changed all the parts. It was easy and I can rest assured that it has been done right, this time!


Installed it right away and have used the trailer many times over the past year and the part I put on works great . The order was shipped fast and well packaged .
I will order from Etrailer again if I need more trailer parts .


The latch in this kit did not work with the coupler on my trailer. I was able to use the old latch with this new kit and get the trailer hitched again.


Great company. I always receive my orders on time. The quality of the products are great. Everything I've received including this hitch latch fit perfectly. Great purchase experience and excellent customer service.


I still use the products I purchased and will be ordering from you again in the future. I am in the process of building another trailer so I will need supplies for it.


Customer service was awesome, we were able to get our trailer back in action quickly! Very happy with this transaction and all the help!


Thanks for the clean and fast transaction; It didnt take long after identifying what hitch I was trying to repair, to match up to your catalog listings.
Good service and fast delivery

Thanks again


Trailer couplerExactly what I was looking for at the best price and shipping cost. Shipped faster than expected.

  • Fulton Repair Kit Recommendation for an A-Frame Fulton Coupler
    Just the handle of the # F640801 isn't available. The good news is that if you order this repair kit you will have plenty of spare parts left over for your coupler. This repair kit fits Fulton 44305R and 44314R series couplers.

  • Replacement A-Frame Coupler Latch Differences
    The difference in the Repair Kit for Fulton A-Frame Coupler 2-5/16" Ball with Wedge-Latch part # F640801 and the Repair Kit Fulton Wedge-Latch Cast Head Coupler part # F670801 is what couplers they fit. Part number F640801 is designed for use with the standard F44305R0317 and F44305R0500 couplers and the F670801 is for use with the cast iron 44125W and 44150W series couplers

  • Replacement Coupler for an Older Gooseneck Trailer Latch System
    Thanks for the photos, Rickey! That is definitely an older style of gooseneck coupler and while I do have a solution for you to get your gooseneck trailer back in working order, we unfortunately don't have any repair latch kit for the style you have on your trailer. What I recommend doing is having an experienced welder cut off your current coupler and weld on the 20K capacity Bulldog Coupler Repair Kit for 2-5/16" Ball # BD0287740300. This gives you a lockable coupler with a newer style...

  • Latch Repair Kit for Fulton A-Frame Coupler
    Thanks for the picture of your coupler. It definitely looks like you have a Fulton A-Frame coupler # F44305R0500 so yes the repair kit part # F640801 would be the correct repair kit you'd need.

  • Availability of Repair Kit for Older Fulton 1-7/8-Inch Trailer Coupler
    We do offer repair kits for Fulton and other brands of trailer couplers. These repair kits are confirmed based on the original coupler series number, which is usually stamped into the housing or printed on a sticker. For example, the Repair Kit for Fulton A-Frame Couplers with Wedge-Latch, part # F640801, fits their 44305R and 4431R series couplers. Repair Kit # F660801 fits their 43805W series couplers and kit # F670801 fits 44125W series couplers. If you cannot find a part or series...

  • Is There a Trailer Coupler Repair Kit for An Atwood Trailer Coupler
    I do have an option for you but trailer coupler repair kits are model specific and since Atwood has went out of business there are no more trailer coupler repair kits for their couplers. I am afraid the only option for you is to replace the entire couper which I know is not what you want to do but is your only option. I recommend the Demco A-Frame Trailer Coupler part # DM16680-52 because of the foolproof eZ-Latch system and the bolt-on installation which means all you need to do is remove...

  • Is There a Repair Kit for a 2-5/16" Trailer Coupler
    I don't think anyone really wants to replace their coupler when the latching mechanism is bad or worn but, it's unfortunately a must since they don't make universal trailer coupler repair kits. There are trailer coupler repair kits available but, they are for very specific couplers which is not likely one you have. That said, we do have bolt-on options so you don't need to worry about finding a welder, you'll just need to cut/grind the old one off. I recommend the Demco 50-Degree A-Frame...

  • Latch Repair Kit Recommendation for a Fulton A-Frame Coupler F44314R0303
    Since you said you have a 14k Fulton coupler it sounds like you actually have the part # F44314R0303, which then for a latch repair kit you would want the part # F640801. The main product picture for the # F640801 shows it in the right orientation. If you look under your current coupler you will see that your wedge is also like this.

  • How to Choose the Correct Trailer Coupler Repair Kit
    I do have options for you but trailer coupler repair kits are not exactly universal. If I knew the exact trailer coupler you have on your trailer then I could confirm 100% whether or not we have a trailer coupler repair kit for you. However, it looks like you have the Fulton A-Frame Coupler part # F44305R0317 which means the Repair Kit for Fulton A-Frame Coupler 2-5/16" Ball part # F640801 would be correct for you. My advice would be to order both the coupler and coupler repair kit. If...

  • Which Couplers Do Repair Kits # F640801 and # F670801
    No they are not interchangable although they do look similar. The part # F640801 fits coupler part # F44305R0500 and then repair kit part # F670801 fits the part # BD44125W0317. Which coupler does your look like between the two?

  • Replacement Coupler Options for a 1963 Boat Trailer With 1-7/8" Fulton Coupler
    The only Fulton coupler repair kits we carry are the # F670801 and # F640801 which are for much heavier duty couplers. Due to the age of your trailer you will most likely have to replace your coupler unless you can find the parts from a used coupler. I do see we have a few options depending on the width of the pole tongue on your trailer. We have a 2" # CT-2001-Z, 2-1/2" # CT-2002-Z or 3" # CT-2003-Z option. All of these are capable of bolting on to the tongue, have a 1-7/8" ball fitment...

  • Availability of A-Frame Coupler Latch Repair Kit
    If you're referring to the Fulton # F44314R0303 you looked at then you can use the Repair Kit for Fulton A-Frame Coupler # F640801. If you have the Buyers Products # 3370091595, a replacement latch is not available which means you would need to replace the coupler. If you do need to replace the coupler, I recommend the Demco # DM13205-95 instead. This has the eZ-Latch which is similar to the Auto-Latch the Buyers Products coupler has. However, this coupler has a repair kit # DM6008 should...
