Video Transcript for etrailer Gooseneck and Fifth Wheel Adapters - Adapts Trailer - KPG5-R25 Review

Today we're going to take a look at the round tube to goose to 5th wheel trailer coupler adapter. It has a 25,000 pound weight capacity. Now this gooseneck to 5th adapter lets you tow your gooseneck trailer with the 5th wheel hitch, has the round inner tube right here and the round outer tube which will replace most standard round gooseneck couplers on your trailer. Connects to your 5th wheel hitch with the king pin right down here. This is an adjustable height. You can see two of the holes. It actually has a total of a 4 hold design to fit your application, so you can pull this pin and clip out to adjust the height.

Once you get the height adjusted then you have the two set bolts to tighten down to hold it into place. This is a sturdy steel construction. If you notice on the plate it has the heavy gusseting between the tube and the plate. It is a raw finish. Again the heavy duty load bearing pin and clip is included and I mentioned the two set bolts right here. This does meet the SEAJ2738 compliance standards. I'll give you a few measurements on this.

The inner tube diameter is going to be 4 inches, outside to outside. On the outer tube, if we go outside to outside it's going to be right at 4 and a half inches. Now the range of vertical adjustments, because there's 4 holes, from the set, if we measure from the center of the first hole all the way up to the center of the top hole that will give you an 8 inch vertical adjustment. Basically between each hole it's 2 and 11/16th center to center. The length of this outer tube right here is going to be 20 inches, the pin hole diameter is going to be 7/8th of an inch. Now the plate is going to be right at 10 inches by 10 inches. The king pin on the very bottom here that goes into your 5th wheel hitch, it is the industry standard 2 inch diameter king pin.

The weight capacity on this again is 25,000 pounds. That should do it for the review on the round tube gooseneck to 5th wheel coupler adapter with a 25,000 weight capacity.

Great product, well built and fits all my trailers, it allows me to leave my 5th wheel hitch in place and still pull my stock/flatbed trailers and saves a lot of heaving lifting.

Added a gooseneck 5th wheel to a 14,000# dumpster trailer using boxed 8x8 wfb. Built it to the truck. This product ideal for this project. Welded on with flat plate allowing space for adjustment. Towing made a huge difference with the trailer maxed out most of the time. Turning around is fantastic with the ability to jack it around up to the cab.

This works great. All we needed to do was swap the 4 inch tube in the trailers 41/2 inch pipe so we could tow our 40 ft gooseneck with our 5th wheel receiver for a much softer ride and simpler hook and unhook. Thank you.

I needed a replacement tube and coupler for an old goose neck trailer since the old one had rusted too bad to get apart. I bought this one and installed it. Good quality, fast shipping. I'm happy I bought it!

Review from a similar e GN to 5W Adapter in Gooseneck and Fifth Wheel Adapters


Very good quality. Welds and fit are excellent. I used this to adapt a 5thwheel. The factory pin box was the wrong style to fit my truck and hitch. This coupler adapter allowed me to use vertical adjustment to let my trailer clear the bed of my truck even when turning. As you can see I cut the coupler down to suit my needs and it seems to have worked very well. My only complaint isn’t even really aimed at the part or etrailer but at usps. etrailer shipped the part the next day and I had it within 3days. The box it came in was shredded!!! Again not really the fault of etrailer or the part but y’all might think about using better shipping containers or using a better shipping company. Also wrapping these bigger heavier parts with sharp corners in shipping Cellophane might help keep the boxes in 1 piece. Thanks!!

I ordered this item and within 2 days it had arrived. Installing it didn’t take over 10 minutes! I use my truck to work during the week and pull my 5th wheel on the weekend! Only thing I’d recommend purchasing is a lube plate to put on the hitch, that way you don’t have to deal with a greasy mess! I’d recommend this hitch to anyone!


Comments
The product is holding up well and works great. It is very convenient being able to switch from my camper to my gooseneck without having the change the hitch out!

My pickup engine went down being unable to pull a my gooseneck with a ball application I ordered your 4 in kinpin adapter for a gooseneck trailer as you can see in the pictures it pinned in perfectly with no trouble at all with your adapter im able to get my trailers moves while repairs are made and with it i'll just have to use the fifth wheel hitch for the pickup witch is much more easy to use than a goose ball

The king pin adapter works great and I won't have to switch back-and-forth between gooseneck ball and fifth wheel hitch anymore. I found the best price at the etrailer.com .
