This hitch is rated for 21,000 lbs gross towing weight and a 4,000 lbs vertical load limit, giving you the strength you need for heavy fifth-wheel trailers. The sturdy steel construction and black powder coat finish add durability and corrosion resistance, so it stays solid and dependable over time. It feels planted and stable when you hook up—exactly what you want when you're pulling serious weight down the road.
The single-piece wraparound jaw completely encloses the king pin for 360-degree contact, which keeps the connection tight and reduces chucking or rattle. A 3/4" thick solid steel locking bar reinforces the coupling and automatically locks when the jaw closes. You can feel the difference in the ride—less metal-on-metal movement means a smoother, quieter trip from start to finish.

The head pivots both front to back and side to side, so it naturally lines up with your trailer during hookup. Built-in polyurethane dampeners help cushion movement and absorb road shock, cutting down on unwanted noise and jarring. The result is an easier connection process and steadier towing once you’re on the move.


The Recon’s two-piece design makes it simple to install or remove without heavy equipment. Just drop the base onto the included 2-5/16" ball from the underbed gooseneck kit, tighten it down, then slide the head assembly into place at your chosen height—15-1/2", 17-1/4", or 18". When you’re done towing, lift it out to get a clean bed ready for hauling gear or other work.


This setup includes a custom underbed installation kit that doubles as a gooseneck trailer hitch. You can tow a fifth wheel one day and a gooseneck trailer the next without swapping systems. Flip the chrome ball upside down into the hitch when not towing for a fully open bed, and use the rubber cover to keep dirt out of the ball hole. The gooseneck system is rated for 30,000 lbs gross towing weight, with a 7,500 lbs tongue weight limit.
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..

Excellent hitch to date and still very happy. Have pulled my fifth wheel around the country with zero issues. I see people with $1800 hitches that have minor slop and problems hooking up at minor funny angles. This hitch is strong, simple, and very secure. No slop.

I have a solution to your issue. The bag with the bolt and nut for the hitch handle should have came with a small round dampener that stops the hitch head from flopping back and forth in the truck. The urethane compresses under a load so it does not restrict the fore and aft movement when coupled. Before you attach the hitch head to the saddle assembly the dampener will need to be installed. Simply press it into the hole that is punched into the bottom side of the hitch as shown in Figure A of the instructions: https:cdn.demco-products.comdocumentsHJ26169.pdf

Pretty good. Still rotating a little. I tightened the main bolt to the ball more than the 30lbs. It’s not rotating as much as it has been. Still haven’t figured out if or where I would drill a hole for a bolt to go in. I’m not really wanting to do that yet.
