The built-in automatic slider gives you an extra 14" of clearance when you turn, letting your trailer glide smoothly around tight corners without getting out to move a manual slider. The rack-and-pinion gear system inside the base handles this movement automatically, shifting the hitch head toward the tailgate during slow-speed turns and back toward the cab as you straighten out. It’s a simple way to make cornering easier and protect both truck and trailer during those close maneuvers.
The wraparound, single-piece jaw completely surrounds the king pin for 360-degree contact, giving a tight, no-rattle connection. A 3/4" thick solid steel locking bar reinforces that connection and automatically locks when the jaw closes. Together they cut down on movement and deliver a smooth, quiet tow that feels secure over every mile.
The double-pivot hitch head moves front to back and side to side to help reduce chucking and harsh feedback. Three polyurethane dampeners cushion that motion and soak up road shock, so you’ll feel less jarring from bumps or dips. It also pivots naturally as you hook up, tilting into position for an easier alignment with your pin box every time.
Installation is straightforward thanks to the included rail adapter that drops right into the puck receivers of your prep package. Once it’s locked in place, you can pin the preassembled base and bolt on the side plates. The adjustable height—15-1/4", 16-1/2", or 18"—lets you fine-tune for your setup. The spring-loaded handle with a comfort grip and tethered safety pin make coupling and securing the handle easy once everything’s in place.
With a gross towing weight rating of 21,000 lbs and a vertical load limit of 5,250 lbs, this solid steel hitch is ready for serious fifth-wheel towing. The rust-resistant black powder coat finish adds durability and keeps it looking clean even after long hauls. It’s a heavy-duty build that feels solid every time you back in and lock on.
This fifth-wheel trailer hitch is not compatible with Sidewinder or Revolution king pins. Do not use any device that changes the pivot point of your trailer's king pin with this hitch.

Hi, everybody. Andy here with etrailer.com. Let's take a look together at this Demco 5th Wheel Rail Adapter Now, this adapter is specifically designed to fit your 2016 and newer Nissan Titan XD with a 6.5 foot bed with the OEM integrated Gooseneck and then your 2017 to 2019 Nissan Titan XD with an eight foot bed, again with the OEM integrated gooseneck. Now, on custom fit parts such as this adapter, I do recommend taking advantage of our vehicle fit guide here at etrailer.com. Simply input the year, make, and model of your truck and our fit guide will confirm if this will work for you or if we have something comparable that will work for you. Now, this adapter is going to be perfect if you want to use your standard 5th wheel trailer hitch with your Titan XD truck's factory-installed underbed 5th wheel mounting kit.
This is going to let you use your 5th wheel trailer hitch that attaches to the standard above bed rails. However, I do wanna point out that this adapter will not work with the B&W Patriot sliding hitch. So just so you're aware of that. Now this is going to mount to the two OEM pucks. And then the center shaft that you see there, that's going to insert into the gooseneck ball hole in your Titan's bed.
So with this little bit closer underside view, hopefully you can see these pins here. Those pins are what's gonna drop into the the puck there, and then that center shaft is going to drop into that gooseneck ball hole. Now, this does use a ball bearing locking system. So right now I have it locked, but let me go ahead and unlock this. So this does include this thumbscrew with a washer.
So I'm gonna go ahead and remove that thumbscrew. And then if you just turn that slightly, taking another view close up, as you can see, hopefully those ball bearings are loose in there, so they're not secured. But after you have this dropped into place, into that puck system and into the gooseneck ball hole, you're just going to turn this latch like so. That's going to secure those ball bearings and make them to where they're not gonna be able to go back into the shaft. Insert the thumbscrew, tighten it down.
And then taking a closer look here, those balls are going to be secured into place. So hopefully you can see that. So this is made here in the USA of a rust-resistant black powder-coated steel construction. So this is very strong, very robust, very durable. This has a maximum capacity of 21,000 pounds. Instructions are included to guide you through the very simple installation process. However, I do wanna point out that even though this is going to be a very easy setup, a very easy install, this is a very heavy adapter. So you do wanna make sure that you have at least another person with you to help you lift this into your truck bed and then drop it into place. Well, I think that's gonna wrap up our look today. I do hope that our time together was helpful for you. Again, my name is Andy, thank you for joining me.

We installed and removed our fifth wheel adaptor many times and it has continued to work well.

Thank you for the review! While I do see where a hole in the mounting bracket would make this easier to remove with your Adapter Plate # DM6333, a solid bracket in this instance is much better for strength, especially considering this hitch is designed around the universal rails for trucks.

In the description it says locking plates, sold separately, are required for the Rota-Flex Pin box that you have. Item # DM6171

After about 6000 miles the hitch developed some fore and aft movement. After another 2000 miles it seemed to be excessive with a loud clunk when stopping and starting. Yes, I do grease it as per instructions before each trip. I called Demco and told them the problem and they sent me the parts I needed at no charge since it was under warranty. Since I had the mechanical ability I disassembled, diagnosed and repaired it myself. I thought later on that I should have been compensated something for my time only because if I took it to a dealer they would have charged for labor. Just a suggestion, there needs to be an easier way to lubricate this hitch rather than removing the large pivot pin and also the large pivot bolt and greasing them by hand. Some well placed grease fittings would make this job a lot easier and cleaner, especially when on the road. Also, the hitch owner would be far more inclined to do it. Other than that the hitch has performed great and I am very happy with it. Thanks.
