This hitch takes the stress out of cornering in tight campsites or parking lots. The automatic slider gives you 22-1/2" of travel front to back, so the hitch head moves toward the tailgate when you turn and back toward the cab when you straighten out. There’s no need to get out and pull a manual lever—everything happens smoothly and under control as you steer. The roller-and-guide assembly handles the motion so the hitch slides itself, keeping your trailer clear of the cab on slow, sharp turns.
The single-piece wraparound jaw locks completely around the king pin, giving a tight, 360-degree connection that cuts down on rattle and movement. A 3/4" solid steel locking bar reinforces that connection and automatically locks when the jaw closes, adding an extra layer of security before you roll out. The result is a solid, quiet link between truck and trailer that stays steady mile after mile.
Hookups are straightforward thanks to a double-pivot head that tilts front to back and side to side. It automatically aligns with your pin box as you back in, helping the king pin settle in cleanly. Three cushioning polyurethane dampeners soak up shock and reduce noise from road chatter, so towing feels smoother and quieter whether you’re crossing town or covering long stretches of highway.
With a gross towing weight rating of 13,000 lbs and a vertical load limit of 3,250 lbs, this hitch is ready for serious fifth-wheel duty. The heavy steel construction and rust-resistant black powder coat finish give it lasting strength against wear and weather. It’s a solid setup that inspires confidence every time you hook up.
Installing this hitch is simple with the included above-bed base rails and brackets. Once mounted, you can dial in your height using three preset settings—15-1/4", 16-1/2", or 18"—to get your trailer level and maintain proper bed rail clearance. The spring-loaded handle with tethered safety pin makes coupling easy and secure once everything is set to your preferred height.

Hello everybody, this is Jeff at etrailer.com. Today. We're going to take a look at this Replacement Head and Base Assembly for the Demco Hijacker Autoslide 5th Wheel Trailer Hitches. Has a 13,000 pound gross towing weight capacity. Now this will replace the head and the base assembly on your Demco Hijacker Autoslide 5th Wheel Trailer Hitch. It is designed to fit the hitch part number DM8550040 and part number DM8550041.This 5th Wheel Hitch will mount in the bed of your short bed truck so that you can tow your 5th Wheel Trailer.
The hitch does come all pre-assembled for easy installation, all you have to do is bolt on the side plates and attach the head to the hitch face. Now, this does offer an automatic slider, which provides clearance that's required for your short bed truck to turn safely at slow speeds. There's no more getting in or out of your truck to operate a manual slider.This rotating hitch head will turn up to 90 degrees with your trailer. The rotation will create the force that propels that automatic slider. So basically the head will slide towards the tailgate when you turn, and back towards the cab when you straighten out.
Total travel it'll give you as about 22 and a half inches front to back. The roller and guide assembly that's underneath here in the base, creates a nice, smooth and controlled movement. If you notice on the hitch head right here, they have these built-in brackets. This just stabilizes your pin box so the king pin won't rotate in the hitch, and there is no need for any separate capture plate for a standard non cushion pin box.It is a rail free design, allows for full access to your truck bed when the hitch is removed. Does offer two separate tracks to allow for up to two and three quarter inches of side to side clearance, to keep your pin box from hitting your bed rails.
The jaw on this hitch head here is a nice wrap around single piece jaw, provides a nice secure connection. Gives you a 360 degree jaw to king pin contact, which will give you less rattle, more security than the slide bar jaws. Now, at the end of this video, I'm going to demonstrate how the king pin will slide in here. It does also use, if you look in front of the wraparound jaw, this bar right here, it's a three quarter-inch thick, solid steel locking bar. This'll reinforce the connection of your coupled trailer.
This will automatically lock into place when your jaw closes.The hitch head itself is a double pivot hitch head, eases hook-up helps limit chucking, pivots front to back and side to side. They do use cushioning polyurethane dampeners underneath the hitch head to help reduce noise, absorb any road shock. And the handle on this head is a nice spring loaded handle, has a nice comfort grip, allows for simple coupling. And they do use this tethered safety pin right here you can see. And when it's closed, to lock it in place you drop it through and clip it. And then to open it you just remove it, and it is tethered, you can see if you let it go you won't lose it. Go ahead and put it back in there.Now this is a nice sturdy steel construction, uses rust resistant black powder coat finish. It is made in the USA. Few specs again, the application, it fits standard pin boxes from 12 inches to 14 inches wide. Now locking plates, which we do sell separately, are required for use with the following cushion pin boxes: The Glide Ride, the Mor Ryde, the Trailair Tri Glide, and the 5th Airborne. Gross towing weight capacity on this is 13,000 pounds, vertical load limit or pin weight capacity is 3,250 pounds. Now it does come with this nice operator's manual that'll describe how everything goes together and how it operates.And again, the last thing I do want to show you, here's an example of what the king pin would look like on your 5th wheel. So when you go to hookup, what you'll do again is remove the safety pin there, and then you'll take your handle and pull it all the way out. Once you get it all the way out, it locks into the open position. So you can see it's going to allow the king pin to slide in there and push up against the jaw. So you can see when it gets in far enough, just like that, the wrap around jaw comes around. And that bar we talked about will slide all the way across and lock into place, give you that extra security. Now you're all ready to go. All you have to do is take your safety pin, drop it through the hole, flip it and it's locked the handle, you're all ready to go. To disconnect it all you have to do is, again, pull out your handle and that'll allow you to remove the king pin from your jaws.But that should do it for the review on the Replacement Head and Base Assembly for the Demco Hijacker Autoslide 5th Wheel Trailer Hitches. Has a 13,000 pound gross towing weight capacity.
Ratings & Reviews
arrived on schedule, heavy , need at least 2 people to lift into truck bed, installed in about an hour. worked well on our first trip using it.
Heavy as hell. Shims should be in smaller increments. Took a sledge hammer to get pins to finally seat in pucks and to close the locking handles. Took apart and back together 5 times to get it right. Not enough play in the system in my opinion but I have zero experience with OEM 5th wheel prep stuff so who knows. Ultimately in the end it's installed and feels tight. Backing 90 degrees i didn't see and slide but maybe it knows what it needs to do better than I do.
The product is very well built. The instructions could use some clarity on exactly which bolts go where.
Very well built. Will need some sort of hoist to place in the truck bed. Need to verify your minimum hitch height as this one will only go down to 16 1/2”.
I like to hitch but unfortunately doesn’t work for my trailer as it won’t travel level meaning it was to high in the bed of the truck causing to much weight to be on the rear axle of the trailer which will cause other issues like wearing tires, wheel bearings, axles and could cause rear tires to blow out while traveling. With discussion with Will at ETrailer we worked out to use a stationary hitch until one can be available for our situation. Will was excellent to work out our options.
The help I received during online chat, set me up for the right parts and fast service as was needed for my project. This Merchant was recommended by my Hitch manufacturer. It is not the first time I've used them, and they are the first ones I think of when exact special parts are needed. Thanks E-Trailer for helping me out! This particular item was a premade bracket that fit onto a Rhino King Pin Box to fit properly onto a Demco autoslider for proper workability.
Worked well to adapt my Rhino pin box to the Demco Auto-Slide hitch head. Will be switching pin boxes at some point so for me, not a permanent solution. Very happy with it overall and would use/buy again if in the same situation.
Installing was relatively easy. Made my silly Rhino hitch work with auto slide.
This hitch is very well made. Its very heavy and will require some kind of lift to get into the back of the truck. I used a foldable engine hoist. The puck system works well as long as the pucks the truck manufacturer installs are cast correctly. One of the RAM pucks had some slag or casting imperfections that had to be removed for the hitch to go into the puck. Once that was cleaned up the hitch installed very easily. Another thing is this hitch has no rattles when I am not pulling a trailer.Very impressive to other 5th wheel hitches I have used. The hitch works as intended as I do not have any issues with clearance in a full 90 degree turn. When turning at a 90 on a grade or large angle which sometimes causes clearance issues this hitch I have not had any issues.
Working perfectly. Delivered via LTL, the carrier called in advance to schedule delivery to our home. I requested a lift gate at delivery. Driver picked up the (1) skid (approx. 500 lbs.) with pallet jack, moved it to the lift gate. I backed the pickup truck receiving the hitch to the back of the carrier truck and put down the tailgate. Driver lowered the lift gate to the same level as the tailgate of the pickup truck and moved the pallet from the lift gate to the back of the pickup using the pallet jack. All done in the street in front of our house. No problem!
I assembled the hitch in the rear of the truck by myself. Everything lined up perfectly with the "puck" system. Install took a few hours since I was on my own.
First hookup with 5th wheel was a little problematic. Hitch would not engage when the king pin hit the back of the hitch. Being new to a 5th wheel hitch, I thought I was doing something wrong. I got a neighbor who had years of experience with 5th wheels to take a look - we still were having problems getting the new hitch to engage. As it turned out, the king pin on the camper had a little corrosion, which we cleaned off and added a little grease. We added a touch of grease to the new hitch at the point of contact with the king pin. Hooked up on the next try and every other try (probably a dozen or more) since then.
Did some practicing on sharp turns and the automatic slide works perfectly! Full clearance between cab of truck and camper in all the turns we attempted. I did a lot of research and stressed a good deal over this purchase - so excited it worked out. Knowing what I know now, I'd do it again!
Worked out great. I used the hitch for my camper right after I installed it. However, I did break one of the bolts when installing it, which is OK. I just switched to grade 8 bolts which is better anyways. I love the fact that Demco hitch unlocks when you pull the lever regardless of weight on it. Compared to my previous Mopar hitch you had to get at the right weight pressure to unlock it.
Seems to be built very well, and installation was fairly easy considering the size and weight. Won’t know how it travels until I get the RV in the Spring….we shall see! In my particular case, I had to use spacer washers between one of the brackets and the hitch so it wouldn’t jam in the truck mounts but no big deal.
I’ve also figured out a way to “store” the hitch for the winter.
everything i have bought i am very happy with and will buy again.
Everyone that I spoke to on the phone were very helpful. I haven't hooked up my hitch yet but I like what I see so far.
Didn’t realize it was 13k thought it as the 18 k I wanted….
Heavy duty
Trailer rep,Alex, was very knowledgeable about the products and was a great help with helping me select the correct trailer kit for my truck.
Your team was very helpful getting me the hitch that I needed, and it arrived a little sooner than expected. In fact my truck is still in the repair shop for the damage caused by the other hitch, so I have not installed the new one as of yet.
Thanks for all your help.
Hitch works great, my truck has a 5’7” box, I can back up turning 90 degrees if I need to. It’s very important that your pretty straight when you unhook or you can’t hookup. You have to be more accurate when hookup. The first few times it seemed like it was going to be a hassle, you just have to pay a little more attention. Hitch is worth it
Wow, where to begin. I can't imagine towing a 5th wheel trailer in a shorter bed truck without an autoslide setup. After the initial install I noted on the 2nd(?) trip a clunking noise during acceleration after a stop - a couple emails back and forth with Demco support, as well as a quick phone call, and it was all sorted out (user error) with no further issues - Thank you Demco!
I tow a short & light Jayco 5th wheel with a 1/2 ton shortbed and having the ability to drive, turn, and park the camper without having to get out of the truck to manually engage or disengage a slide on the hitch has made for much more relaxing weekends away. The Hijacker autoslide gives PLENTY of space between the camper and cab and I've never had to worry, but I did my homework and ran the numbers well before I purchased my hitch so I wasn't surprised.
I would say the only downside for me would be the weight and bulkiness of the hitch. Not having the means to easily remove and store it between trips, the hitch is forced to live in the bed of the truck right now, but I did know about the weight going into the purchase.
All in all, for the peace of mind the Demco autoslide gives me, I'd spend the money all over again.
Do you have a question about this 5th Wheel Hitch?
