Note: 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.


Automatic Slider Makes Cornering Easy

Most often used on trucks with 6-1/2' beds, a slider helps to eliminate clearance problems during slow-speed turns. When you are towing a fifth-wheel trailer, your hitch must be situated on the cab side of your truck's rear axle. However, at slow speeds you can use a slider to slide the fifth-wheel hitch (and the trailer) toward your truck's tailgate and past the rear axle, creating enough space between the cab of your truck and the trailer to permit less-restricted turning.


Normally, you'd have to get out of your truck and pull a lever to release the slider before every turn, but what if there was an automatic system? Imagine having 14" of extra clearance while towing your fifth-wheel trailer. Now imagine having this without needing get out of the truck to move your slider. The Demco Hijacker Autoslide makes this fantasy a reality. The Autoslide automatically glides back smoothly when you make a sharp turn so you can maneuver effortlessly around tight corners within campsites and parking lots.


Demco Hijacker Autoslide

The base of the Autoslide has a built-in rack-and-pinion gear system that operates automatically. As your truck turns, the pinion in the base also turns. This activates the rack gear, which causes the rotational force of the truck to be converted into the linear sliding action of the hitch. So, when your truck makes a sharp, slow-speed turn, the gears inside the Autoslide force the hitch head to slide down toward your truck's tailgate in a smooth, controlled motion. This way, any time that your truck turns more than 10 to 15 degrees, the Autoslide will ensure that there is enough clearance for your trailer to complete the turn as well, and it will do so without any jerking or binding.


In order for the rack-and-pinion assembly to function as designed, the pin box must be stabilized on the hitch head. Normally in a fifth-wheel hitch, the king pin moves inside of the hitch head so that the trailer can turn. With the Autoslide, the king pin remains fixed inside of the jaws of the hitch and it is the hitch head itself that turns. This is thanks to the capture brackets on the sides of the head that brace the pin box from both sides to hold it in place on top of the hitch head. This is done to ensure that there is enough resistance within the hitch when your truck turns to properly activate the rack-and-pinion gear mechanism.


Demco Hijacker Autoslide capture bracket

To stabilize your pin box on the hitch head, simply push the capture brackets up against your pin box once the trailer is coupled and tighten the outer bolts and the inner jam nuts. The Autoslide head and brackets will fit standard pin boxes that are between 12" and 14" wide. If you have a Glide Ride, Mor Ryde, Trailair Tri Glide, or 5th Airborne pin box, you must install a special locking plate (sold separately) as well.


When you straighten your rig out again and your trailer moves back in line, the hitch head will rotate back to center and slide back toward the cab into the straight towing position.


Secure Wraparound Jaw with Locking Bar

Demco Hijacker Autoslide wraparound jaw and locking bar

The single-piece, strong wraparound jaw completely surrounds your trailer's king pin for 360 degrees of contact. This wraparound jaw provides a more secure connection than standard 2-piece jaws that close in on the king pin from the sides. The increased jaw-to-king-pin contact on the Autoslide offers tighter tolerances around the king pin, which minimizes both rattle and chucking, for a smooth, quiet ride.


A 3/4" solid steel locking bar spans the area in front of the jaw. This bar provides an added barrier of protection against accidental disconnection so you can have peace of mind that your trailer is secure. The locking bar is attached to the jaw and to the spring-loaded handle. The bar automatically locks when the jaw closes around your king pin.


Double-Pivot, Cushioned Hitch Head

The double pivoting, cushioned head improves your towing experience dramatically by helping to reduce jarring and unwanted noise. Built-in pins allow the hitch head to pivot back and forth and side to side. And hooking up is easy because the hitch head will automatically pivot to the proper angle when it comes into contact with your pin box.


Three polyurethane dampeners help to cushion the movement from the pivoting head and to reduce towing noise. Two of these dampeners are built into the head assembly to cushion the head's side-to-side pivoting. The third dampener cushions the back-and-forth motion and must be installed in the hitch prior to use. Installation of this third dampener is easy - simply press the dampener up into the pre-drilled hole underneath the hitch head.


Easy Installation

The Hijacker Autoslide hitch is specially designed to fit a Demco UMS custom underbed mounting kit (sold separately). The hitch comes pre-assembled for an easy installation. All you have to do is bolt on the side plates and attach the head to the hitch base.


The side plates have 2 functions. They contain the feet that fit into the receivers in your truck bed, and they allow you to raise or lower the hitch head to better match your pin box height. After you choose your desired height setting, simply bolt the side plates to the hitch base with the included hardware. Then lower the hitch into the 4 UMS receivers in your truck bed. Turn the handles to lock the feet into the receivers and secure the handles with the included safety pins. The hitch can be removed to give you full truck bed access. Simply remove the safety pins, turn the handles to unlock the feet, and lift the hitch out of the receivers.


Clearance Formula for Short Bed Trucks

Use the formula below to ensure there will be enough space between your truck cab and trailer when executing a 90-degree turn.


(A+B) - C = Clearance


A = Distance from the center of fifth-wheel hitch jaw to truck cab

B = Length of Travel (14")

C = Width of trailer divided by 2 (to get half)


For example: If the distance from the center of the hitch to the cab is 36", 36" + 22" = 58". If your fifth-wheel trailer is 102" wide, take half (51"), then plug in: 58" - 51" = 7" of clearance.


Note: At least 4 inches of clearance is recommended to safely execute a 90-degree turn.

Video Transcript for Demco Fifth Wheel - Sliding Fifth Wheel - DM8550037 Review

Today we're going to review part number DM8550037. This is the Demco 21,000 pound Hijacker Autoslide UMS underbed mount 5th wheel hitch. This Hijacker Autoslide is an automatic sliding 5th wheel hitch. It is designed for short bed trucks with a 6 1/2 foot bed to give you additional clearance between the truck's cab and the trailer during turning maneuvers. It also eliminates the need to get in and out of your truck, have to pull a pin and manually slide the hitch. This hitch will do it automatically by using the rack and pinion gear technology in the base of the hitch.

It will move up to about 14 inches of fore and aft travel to help you get in and out of those tight spots. Basically I would push this to show you how it operates, but it does need some weight attached to this to be able to move properly, so I can't really show you that. Just to try to explain it to you, what happens is, your pin box will slide into here, you'll lock it in place with your locking plate and keep the pin box from rotating on the head, it will actually allow this whole head to rotate and slide back if needed. What happens is, once you're installed and you lock it down and you go to make your turn, if you get to about a 10 to 15 degree angle, it will automatically go back to give you the extra clearance also. Then when you start pulling forward and you get back on the highway for towing, if your trailer goes directly behind the hitch, it will go to lock into this position here. Once it's in this position with the trailer directly behind you, it will not go backwards because there's a guide plate right in here that will keep those rack and pinion gears from moving that way. It has to go and do about a 10 to 15 degree turn before it will even go backwards to give you the extra clearance.

Normally a 5th wheel trailer will pivot in this jaw right here in the kingpin. Again, this autoslide hitch uses this integrated locking system in the head to lock the pin box in place on this hitch head and that will eliminate the need for any additional locking wedges with the standard pin box. Instead, what it will allow you, as I mentioned earlier, this whole hitch head will pivot with that pin box locked in place and then once it gets to about 10 or 15 degrees, it will automatically go closer to the tailgate to give you more space between your truck cab and your trailer on sharp turns. This autoslide hitch is designed to work with standard trailer pin boxes between 12 inches minimum width or 14 inches maximum width. These capture plates right here must be adjusted to the width of the pin box in order for this automatic slide mechanism to operate and function properly. Basically what will happen is, when you back your 5th wheel into here with the trailer hooked up, these capture plates you can see right here, you just push them, same way on this side, in or out and what you would do, is once your pin box is installed, push this up against the pin box as needed. Then with it pushed up against there, you'll finger tighten these two bolts on each side, so just tighten these down and that will hold that bar right there and then run your jam nut up. Do the same on this one and then go to this side and do the same.

With those tightened down, it will lock that pin box in place on top of the hitch head. I do want to mention that if this hitch is installed in any trucks with like a 5 1/2 foot or 6 foot bed, there is no guarantee that you'll get a full 90 degree turn with this autoslide hitch. This autoslide hitch is designed for use with RV style 5th wheel trailers that have an industry standard two inch diameter kingpin. This has a 21,000 pound towing capacity. It is a lower profile design and it has easy access for routine maintenance. One of the easiest things you can do is these jaw pins right here, you can actually reach underneath, pull out the snap rings, pull these pins out, grease them up, push them back in, put the snap ring on, that's an easy way to grease these jaw pins.

It is a lighter weight hitch, for easier hitch installation and removal. One of the nice features is, has a kenyon clip under the head here that you can pull the clip out, slide the long pin out that's about that long, it holds this hitch head into the saddle. With the pin removed, you can lift the hitch head out of the saddle and then it makes this base even lighter if you go to remove it when you're not using it. The head itself is a double pivot head. It will go front to back and it will also go side to side. It does use a wrap around jaw and this will wrap totally around the kingpin and in front of the jaw. It has a nice locking bar for smoother, safer, more secure ride. This autoslide 5th wheel hitch will come fully assembled from the factory, just like you see it here, helps make the installation easier and quicker. The only thing you do need to add, it does come with the side plates like these right here, I've already attached those to the hitch, these would come unattached and you'll just have to put them at your correct hitch height you need right on the side here. That's the only extra work needed. You just got to bolt these onto your hitch base. These side plates are what connects your hitch to the underbed rails. You'll see the tabs right there, that's what goes into the underbed rails on your vehicle. The underbed rails and the installation kit we do sell separately on our website. What I would recommend on those is go to our website, use our fit guide, put in your year and model vehicle and it will show you the correct bed rails and installation kit you would need for your application. On the vertical height adjustments, when you'd go to attach these, there's two rows of holes on the plate and there's two rows of holes on the hitch base itself. It will give you about three different vertical height adjustments. A hitch height is measured from the truck bed to the top of the hitch head, so this will give you, depending on how you install it, the lowest it will give you is 15 1/2 inches hitch height. The middle adjustment would be 16 3/4 and the highest would 18 1/4. That gives you three different height adjustments to get it correct for your application, so your truck and trailer are level. Also, on these side plates, just to show you how they operate, what you'll want to do to install them, you'll see these pins and clips right here, just pull the clip out, pull the pin out, pull the clip, pull the pin. Then you'll notice there's these handles, you just pull these out 90 degrees and that rotates these tabs. If you do it on the other side with these out like that, that'll allow you to drop this hitch into those underbed rails once it's fully in place. To lock it into place, just push it back the 90 degrees and it will rotate those tabs 90 degrees to lock them into the underbed rails. Once that's all done, take your pin and clip, slide it back in, put your clip on and this side and you'll be doing the same thing on this side. Just like that, that will keep those from opening and keeps it locked into place. One other thing I do want to mention is, on the very front right here I've already attached this outrigger bar. You'll see the long bolts on it. That outrigger bar is designed to help carry and distribute the hitch and the trailer weight when the hitch is at it's full travel distance. This outrigger bar will help eliminate any movement of the hitch in the truck bed. One thing you want to make sure though, is you adjust that bar after your hitch is installed at it's correct height in the truck bed. This hitch is made in the USA with American steel. Again, I mentioned I can't push this, there's not enough weight on it to show you the rotation but I do want to show you how the jaw operates so when you go to install or you're ready to couple, just take this pin and clip, pull it out. It releases the handle. Pull your handle all the way and you'll feel it lock into place. Now it's open, ready for the kingpin. Just for demonstration purposes, I have an example. This is what your kingpin would look like. It's a two inch diameter kingpin that would be on the pin box. That would be your pin box with the kingpin would be sliding right up into here. You'll see once it gets all the way correctly, that jaw will fully wrap around the kingpin, the locking bar slides to lock it into place. All you'll have to do, take your pin and clip, when you're ready to get on the road, push it in for safety and security and it locks that handle from moving and you're all ready to go. That should do it for the review on part number DM8550037, the Demco 21,000 pound Hijacker Autoslide UMS Underbed Mount 5th Wheel Hitch. .

This hitch has been used daily since i purchased it. I deliver fifth wheel travel trailers all over the country. This hitch has worked flawlessly from day one. This hitch is one of the only products that I've ever bought that is exactly what it was described to be. Im not one to do reviews, so the fact that im doing this one , in itself, says a lot about the quality of your product. The design and looks are much better than any other hitch ive seen. It just looks better in the truck bed than others do. 250140

Review from a similar Demco Hijacker Autoslide in Fifth Wheel


This 5th wheel hitch performs exactly as advertised, automatically extending the trailer rearward whenever making a tight turn with the truck. I can back my short bed Ram 2500 into a 90 degree angle between the truck and the trailer without trailer's nose (Grand Design Reflection 337 RLS) coming too close to the cab. This is why I bought this hitch -- I wasn't interested in having to get out of the truck to manually slide the trailer rearward when maneuvering in tight places. The automatic extending feature of the hitch is the greatest thing since canned beer! 616620

If you have to have a slider this is the one to buy. I’ve now driven with it about 5000 miles..the only down side is that you have to hook and unhook with the truck perfectly straight in line with the trailer. But it does work perfectly as advertised. 517815

Review from a similar Demco Hijacker Autoslide in Fifth Wheel


The hitch works as expected. It is very heavy duty and has held up well. I have pulled a 13,000 pound trailer in excess of 10,000 miles with no problems. I purchased this one because it does not require any adapters for the pin box/capture plate. This means I can pull any standard 5th wheel. The other brands that I found all required a special plate and was specific to the trailer (Not one size fits all). The only downside is that the hitch is very heavy. But that is to be expected for a very heavy duty hitch. 610491


Comments

The hitch is indeed heavy. If you have a chain hoist available, using a lifting bracket like part # DM6100

see link would certainly make installing and removing the hitch much easier.

The hitch was easy to install and works perfectly. It's heavy, so moving it out of the truck by myself is not an option like my old hitch (SOLID construction). Packing for shipment was very good, but plan to have a strong friend or a hand truck (as I did). Installation went well with no issues. Prior to purchasing, I had a couple of questions so I called the company. The rep answered all my questions without issue. 584322

Review from a similar Demco Hijacker Autoslide in Fifth Wheel


I have purchased several different products from etrailer. The folks there have been the most helpful, courteous that I believe I have ever dealt with on the internet... I purchased a demco slider 5th wheel hitch in February 2018. It arrived on time in good condition. I installed in a Ford F-350 with factory puck system I had no issues with install. I did watch the videos online and did find them helpful. I purchased this hitch because with the newer Fords as I'm sure some have experienced they sit about 3" higher than the trucks prior 2017. With my existing hitchI couldn't get low enough and the demco it did allow me to go3 '' lower. Even though the camper still runs a little high in the front its still a whole lot better than what it was. So after one year of use it did work well. It was a little bigger than my previous hitch it and is not an easy job to do by yourself without the help of some sort of hoist. All said I am happy with this product and would give it a good recommendation. 607004

Review from a similar Demco Hijacker Autoslide in Fifth Wheel


Ok... The darn thing weighs a ton! but that was outlined in their info... Just want to make that known. It took three of us to put in the base minus the "head". That was work !! As for the unit, it does as advertised. It swivels when turning and moves aft providing plenty of cab clearance. Don't expect to do a 90 degree turn however, but for normal situations it works fine. One thing I'd love to see is an "adjustment" to move (slide) the "head" a little more rearward when connecting. I only have about 6" of clearance with the gate down so I have to be nearly perfectly aligned to make the hookup. Speaking of which, hooking up can be a challenge. The clamps must have some "slack" and not be too tight against the pin box or alignment becomes a real issue. Also, if you aren't aligned with the trailer when disconnecting you'll need to have that same "off alignment" position when reconnecting as the "head" cannot be moved at all by hand. This can make for having to loosen the clamps, make the hook up, straighten the truck with the trailer and then have to re tighten the clamps. All in all, the unit is as expected and does provide movement aft and forward as you turn. Makes parking in that tight spot a bit less nerve racking... As for Customer Support Demco is spot on!! I had a couple of set up issues. One call cleared the misunderstanding on my end and the install went fine after that. On a second call, they also explained how to set up the clamps to better help with the above mentioned issues. But the nature of the design does not allow much leeway. Enjoy!!! 601243

THE BEST FUNCTIONAL SHORT BED 5th WHEEL HITCH OUT THERE BUT ALSO THE HEAVIEST AND THE MOST DIFFICULT TO REMOVE AND REINSTALL. I HAD TO TAKE IT TO A GARAGE TO REMOVE IT AND AGAIN TO REINSTALL IT. I JUST LEAVE IT IN THE TRUCK BED NOW RATHER THAN FIGHT WITH IT.

Review from a similar Demco Hijacker Autoslide in Fifth Wheel


I INSTALLED THE DEMCO HIJACKER AUTOSLIDE FITH WHEEL HITCH IN MY 17 F250 WITH THE FACTORY PREP PACKAGE. THE HITCH FIT PERFECTLY INTO THE FACTORY PUCK SYSTEM. DID NEED A FRIENDS HELP DO TO THE WEIGHT OF THE UNIT. I AM VERY PLEASED WITH THE OPERTION OF THE AUTOSLIDE AND THE FACT THAT I DON'T REALLY HAVE TO WORRY TO MUCH ABOUT THE TRAILER CONTACTING THE CAB OF TRUCK SINCE I HAVE A 6 FOOT BED. THIS IS THE FIRST FIFTH WHEEL HITCH I HAVE EVER USED BUT WOULD RECOMMEND IT TO ANYONE THAT HAS A TRUCK WITH A SHORT BED. ONLY 4 STARS BECAUSE OF THE LEARNING CURVE OF HITCHING UP AND THE THING IS PRETTY HEAVY. ONCE I LEARNED THAT THE HITCH AND THE TRUCK HAVE TO BE PRETTY STRAIGHT IN LINE DUE TO THE CAPTURE PLATES HITCHING UP HAS BECOME A NONE ISSUE. I DID PURCHASE AN ENGINE HOIST SO THAT I CAN REMOVE THE HITCH FROM THE BED OF MY TRUCK BY MYSELF IF I NEED TO, BUT FOR THE MOST PART IT JUST STAYS MOUNTED. I ALSO LOVE THE FACT THAT IT HAS A HIGHT ADJUSTMENT WHICH ALLOWED IT TO STILL FIT UNDER MY BEDS TONNEAU. OVERALL VERY SATISFIELD WITH PURCHASE 600745

Review from a similar Demco Hijacker Autoslide in Fifth Wheel


I have owned this unit for over a year now. Here are the pro's and cons that I have experienced. Pro- I have pulled with this hitch in some really tight spaces in forward and reverse and still have the rear window in tact. Con- Heavy, really heavy. Pro- heavy duty,smooth riding, and double jaw lock makes a great connection. Con- manufacturer recommends 1/8 of separation between the slides on the top of hitch. When backing upon 40' wheeler in some tight spaces it is hard to align without opening the slides a bit more. This is not he issue. Remembering to tighten them in the rush of leaving is the hard part. Pro- once you are attached to your truck there is nothing more you need to worry about until you disconnect. Con- If you are a weekender like me and use your truck for work the rest of the week, you will need at least one person to help lift in or out pre or post travel. Works pretty well with gantry crane. 604256

This is an awesome piece of equipment. It has worked flawlessly and got us out of trouble on more than one occasion. It allows such a tight turn that you can get pretty brave with your turns. I love this hitch and everyone that witnesses what it can do is amazed. 263968

I am very happy with the hitch. Because I have a short box truck I needed a hitch that allowed me to make turns without having to manually move it back. This product has worked fine. When I turn it moves back smooth. I am glad I bought this hitch. THANKS AUBREEY 319923

Hello, This hitch has been awesome. It works perfectly all the time. My only gripe would be that the head doesn’t fall down automatically. I have to get out of the truck to tilt it down when connecting to my trailer. Other than that, I’m very satisfied with the design and operation of the hitch. Thank You 521792

My wife and I are full-time RVers, and have used this slider hitch from the get-go while traveling around seeing the country over the past year. We are happy with our purchase, which has proven to be both easy to hook up, adjust, and functions well, as advertised. The only matter I think you may want to address are the thick plastic removable maintenance access covers which tend to bow, and the areas around the attachment holes have melted, in the hot weather. Perhaps instead using a light metal for the covers would be better solution. We are very happy overall with this hitch, and plan to keep it . Thank you. 593790

Nice product. Pretty much idiot proof once you get it set up. After that just hook up and go. No worries about crushing your cab when running a short bed. Built well. Heavy duty. Only complaint would be the weight manually getting it in and out. 301924

The Demco slider hitch is an awesome hitch but it does have it's glitches and we are still working those out. But it is so convenient not having to get out of my truck and pull levers to make tight turns. Also, eTrailer has been exceptional with any problems that I have encountered and has gone above and beyond to make sure that I am satisfied with their products. 553103

Review from a similar Demco Hijacker Autoslide in Fifth Wheel


The Demco hitch works okay once it is latched, but it is really hard to get it locked to the pin. The saddle tries to fall forward, making it hard for the pin to hit home. Once while hooking up, it seemed to be latched, but when I pulled forward, the whole trailer landed on the bed sides! Luckily, the pin landed on the base of the hitch, and no damage was done to the puller, even though the trailer made contact with it. It is difficult to hook up because you have to be pretty much exactly straight with the pin box. Sometimes when I start out from a standing stop, it will jerk really hard. I haven't figured out what causes that. I will give this hitch 2 stars because it is so hard to hook up. 465626

After taking out two rear windows over the years, this was the only way to go. It took me a couple of tries to get the right height and I should have mounted the hitch to the rear in its rails. I think that's mostly on me because I am used to assembling things so I must not have been understanding the instructions. Anyway, once mounted it is a thing of beauty. This is the hitch that is built for the factory installed mount in our new Ford Superduty and it fits like a glove. 472960

this unit is great! I have used it several times. All last year including going to Pennsylvania. If I had to rate one fault it would be when we start out from a dead stop it jerks with a noise. Other than that it is great and would not give it up. 365724

  • Fifth Wheel Hitch and Tonneau Cover Recommendation for 2017 Ram 3500 with Short Bed
  • For your 2017 Ram 3500 6-1/2 Foot Bed without Factory Rail Kit you'll need a slider hitch to allow you to make tight turns without cab interference. My favorite slider hitches are the ones that automatically slide as you make tight turns as that saves you the hassle of getting out and activating the slider every time it's needed. For that I would recommend the Demco Hijacker part # DM8550037 and the install rail kit part # DM8551006. This is an underbed rail kit too which means when...

  • The autosliding 5th wheel hitches are definitely the way to go with a truck bed that is under 8 feet, like your 2017 Ford F-350 with a 6-3/4 foot bed. I like to recommend them because they eliminate the need to get in and out of your truck when cornering. They also feature the single wraparound jaw for full 360-degree contact with the king pin and a 3/4 inch steel locking bar for added security. The cushioning that they provide helps to reduce chucking and jarring and the brackets on the...
