This hitch is made for serious towing. It’s rated for 21,000 lbs gross towing weight and a 4,000 lbs vertical load limit, giving you plenty of strength for heavy fifth-wheel trailers. The base and head are built from sturdy steel and finished with a rust-resistant black powder coat that holds up to long miles and rough weather. Once hitched, the setup feels solid and stable so you can pull with confidence wherever the trip takes you.
The wraparound, single-piece jaw completely surrounds the king pin for full 360-degree contact. That tight fit cuts out the rattle and chucking you get from slide-bar designs. A 3/4" thick solid steel locking bar adds another layer of protection by reinforcing the king pin connection once it’s closed. The jaw automatically locks when coupled, creating a worry-free hookup that stays quiet and secure on the road.

The double-pivot hitch head helps smooth out your ride by letting the head move both front-to-back and side-to-side as the trailer moves. Polyurethane dampeners built into the head assembly absorb road shock and reduce noise, keeping things more comfortable during long hauls. The head automatically pivots into position when connecting to your pin box, making hookup easier even on uneven ground.


When it’s time to haul something other than your trailer, this hitch breaks down quickly into two manageable pieces without special tools. The base attaches to a 2-5/16" ball from the included underbed kit—Curt’s Double Lock gooseneck system—which also lets you tow a gooseneck trailer when needed. Flip the gooseneck ball upside down for a clean bed when you’re done towing. With three height settings at 15-1/2", 17-1/4", and 18", you can dial in your setup to get the level ride you want.


This fifth-wheel hitch is not compatible with rotating pin boxes.

Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at this Replacement Base Assembly for the Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter. This has a 21,000 pound gross towing weight capacity. Now this part will replace just the base assembly that's on the Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter, which is part number DM8550045. Now that adapter, we do sell separately on our website. Now this is just for the base assembly.
It does not include the hitch head. The hitch head bolts to this center post here. The hitch head, we do sell separately. It's part number DM6169. The center post right here that the hitch head attaches to, has three different height settings to fit your application.
And the hitch height is critical 'cause when you go to tow your fifth wheel, you do wanna make sure you're towing as level as possible. And hitch height is always measured from the top of the truck bed to the top of the hitch head. And now the hitch height settings on this center post, there's three holes in it. So it gives you a selection of three different hitch height settings. Either a 15-and-a-half inch, 17-and-a-quarter-inch or 18-inch hitch height setting.
You just pick the one that works best for your application. Now, this base also, when you do install this over the gooseneck ball, it does give you a three-inch offset for extra clearance of your fifth wheel. It is is a sturdy steel construction. Has a nice rust-resistant black powder coat finish on it. And it is a quick, simple installation.
Basically, this just installs over the gooseneck ball and it's held in place with the pin and clip. And also these two set screws right up front here. This part is made in the USA and again, the gross towing weight capacity on this base assembly is 21,000 pounds. But that should do it for the review on the Replacement Base Assembly for the Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter..

Ive owned it and used it for a year now and still highly recommend it to anyone with a Gooseneck hitch in their rig. Id add some pics showing how level everything sits, but not sure how to do that now.

This product is far superior than the rest of the other adapters. It mounts on the gooseneck easy and even if I didnt have a gooseneck trailer or gooseneck hitch on my truck this product is better than any other fifth wheel than that Ive had in the past. Plus it gives me the best of both ways to haul any trailer.??

It worked fine while I had it, but upgraded to a Goose Box. The hitch was simple to use, but still rough with a rigid pin box. Also wanted to use the space in my truck bed without having to remove the hitch.

No complaints. Very pleased with the hitch. Much better than the 5th wheel trailer to goose nec ball adaptor I was using.

I would like to add to my 1 year review. Installation was very straight forward and simple. The only thing I did different was to drill a 716 hole on each side rail, into the channel beam that my gooseneck ball is mounted in. This added a little security to the mount but mainly, made it a bit more of a challenge to steal the unit. I do have to take the two bolts out to remove the hitch but only adds about 10 minutes to the process.

Hey Alex! Thanks for taking the time to leave your review and include a pic of your set up! I did some searching and I think the little blue part your are referring to is the urethane pivot bumper. That should go on the underside of the 5th wheel head yoke. I linked the instructions if you want to get a better idea of where it goes. You can see the blown out view on the last page. Happy camping!
