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 - DM8550022 Review

Today, we're going to review part number DM8550022. This is the Demco 18,000 lbs Hijacker Autoslide UMS Underbed Mount 5th Wheel Hitch. Now, this hijacker autoslide is an automatic sliding 5th wheel hitch. It is designed for short-bed trucks with a 6 and 1/2 floor bed to give you additional clearance between your truck's cab and the trailer during any turning maneuvers. It does eliminate the need to have to get in and out of your truck, pull a pin and manually slide the hitch back or forth. This will automatically slide by using the rack and pinion gear technology that's right here in the base of the hitch and that'll give you about up to 14 inches of 4 and half travel to help get in and out of those tight spots.

Now normally, when you hook a 5th wheel trailer up to your 5th wheel hitch, it isn't designed to turn or pivot in the jaw where the king pin's connected to the hitch head. In this case, the autoslide hitch has this integrated locking system in the head and it locks the pin box in place on the hitch head which eliminate the need for any additional locking wedges on the standard pin box. Instead, what'll happen is this whole hitch head on this will pivot with the pin box locked into place and it'll move it automatically closer to the tailgate which create much more space between your truck cabin in your trailer on short terms. Basically, what happens is with your pin box locked in here on these capture plates, I'm going to show you how these capture plates work but once it's all locked in, what'll happen is when you go to make turns, you can see that the hitch head will automatically move towards your tailgate to give you the clearance and also rotate wherever your turning and then when you're done and you're hooked up, I'm going to go back into the tow position. What'll happen is it'll just automatically go back into the tow position and you can hear it sort of relax into place and the reason what's nice about this is once you get this far, when you're get up on the highway and you're towing it, it's not going to allow it to move automatically because what happens is when you get into this position, there's a guide here that'll hold that rack and pinion gear into this position so it will not go if the trailer's directly behind your tow vehicle. It will not pull it directly back. There has to be at least about a 10 to 15 degree turn to get it to automatically move.

What happens is now this autoslide hitch is designed to work with standard trailer pin boxes between the minimum of 12 inches to up to 14 inches maximum. These capture plates I had mentioned which holds the pin box in place, these are adjusted to the width of the trailer pin box in order for the slide mechanism to work properly. Basically, what you do is with your trailer hooked up, pin box all installed, you'll notice . Let me just remove one of these and you'll notice that these capture plates right here, it will slide. You can see they move back and forth. What you want to do is you want your trailers hooked up, there's a capture plate on each side, you'll push this up against the pin box and left it up against the pin box and lift it up against the pin box then you'll tighten down both of these bolts and it'll hold that into place and then run the jam nut up.

Tighten that down. Do it on this. Do it also over here so that'll lock that pin box in place. With them in place, it will keep that pin box from rotating on the hitch head. It'll let the hitch head do the rotating. Now the thing you need to remember, if this hitch is installed and any trucks with a 5 and 1/2 foot or a 6 foot bed, there is no guarantee that you'll get a full 90 degree turn with this autoslide hitch.

This autoslide hitch was designed for use with the RV style 5th wheel trailers with the industry standard 2 inch standard king pin. This does have an 18,000 lb towing capacity. It is a lower profile design which gives you easy access for routine maintenance on the simple maintenance. One of the simple maintenance things you can do is these 2 pins right here, you can get up underneath. Just pull the snap rings out. These pins can slide out. You'll grease them, drop them back in, attach them with the snap rings. It's a very easy way to grease the head and the jaws just by pulling those pins out. This hitch is at a lighter weight for easier hitch installation and removal and the other nice feature is there's a pin and clip here that you pull. Slide this long pin out, it'll allow you to pick up the head and remove it and then makes the base slider to remove if you want to take it out when you're not towing. Now the head itself is a double pivot head. It will go front to back as you can see and it will also side to side. It does use a wrap around jaw with a locking bar infront for a soother, more safer secure ride. This autoslide hitch does come all assembled just like this one from the factory. Makes it easy for installation. The only prep work necessary is you'll bolt these side plates to the auto glide hitch in the correct hitch height position. On the plates, there's 2 rows of holes. On the hitch itself, the base, there's 2 rows of holes so you can actually get 3 vertical height adjustments to get you to the correct hitch hike you need for your application. The side plates that you're bowling on and I've already done it on this. You can see there's one on each side here. These side plates is what'll connect your hitch to your below bed rails. The below bed rails are sold separately. It'll be the below bed rails in an installation kit. We do sell those on our website. They are sold separately and what I would recommend is go to our website and use our fit guide. Put in your model vehicle and that'll show you which under bed rails you'll need for your application. When you do bolt these side plates on, these side plates, you can get 3 vertical height adjustments. The lowest adjustment would be 15 and a half inches. The middle is 16 and 3 quarters. The highest is 18 and a quarter and again, the hitch hike measurement is from the truck bed to the top of the hitch head. You want to get it so you're truck and trailer will be level. Also, you'll notice on these side plates, how they operate. You can see the tabs right here. What you'll do is you have 2 pins here. Just pull the clip off there. Pull this pin out. Pull the clip off here. Pull this pin out and then you'll notice you can just rotate these out 90 degrees. When you do that, you're tabs will rotate 90 degrees and that'll allow you to drop it into the below bed rails that you'll purchase separately for your specific vehicle. You'll do the same on this side. Drop it in, once they drop into there, you just turn them 90 degrees like that. It'll lock these tabs into your below bed rails and then just take your pins. Put your clips in just like that. When you do that it keeps from opening up. Now the other thing I wanted to mention is this outrigger bar right up here we got attached. What that's used for, its in the front of the hitch. It's designed to help carry and distribute the hitch and the trailer weight when this hitch is at full travel distance. This will help eliminate any movement of the hitch in the truck bed. The bar will be adjusted after your hitch is installed at its correct height in the truck bed. This hitch is made in the USA using American steel. I just want to show you real quickly how the jaw operates and we'll move it again. Basically, what you'll want to do to hook up, just pull your pin and clip and then you just take your handle, slide it all the way and it'll lock open. You can see the jaw's open. I have an example here. This is what the king pin would look like on your pin box. A standard 2 and half or 2 inch diameter. When you're backing up, you're king pin's going to slide right into the head. Once it does that, you'll hear this lock. The jaw wraps around the blocking bars in place and just like that once you're ready to go, just drop your pin and clip in and you're all ready. Then again the rotation part I mentioned earlier, you can see as you're turning, once you get to the 10 or 15 degrees, it'll automatically go and then when you're ready to tow, get back on the hull. You'll see that it'll go straight and out. Boom. Locks into place and again, it won't go back straight. That should do it for the review. Part number DM8550022.

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.

Hitch works perfectly. The auto slide is awesome! Very well built. Very heavy. Not something you want to be taking in and out of your bed all the time. My only complaint is that you have to be pretty straight when you hook or unhook the camper. 567589

Awesome product. Works flawlessly! Only drawbacks are the weight, shes heavy. But that just means made well in my book. I'd recommend it any day 575823

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

by:

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

Overall I love the auto slider mount and it works as advertised. Easy to hook up and unhook. Just have to make sure your truck is in a straight line with the RV when unhooking because you don’t want to leave this thing turned or it can be very hard to hook back up. I learned this the hard way. Turning it by hand does not work either. The plastic inserts to cover the holes when the mount is removed don’t work because the holes are too shallow on my F250,, but that makes no difference to me because the mount is way to heavy to remove anyway. The only thing that does bother me is the rust. I have used a wire brush and rustoleum paint on several spots now. Perhaps better rust proofing would be something the company could look into for future mounts. I mounted mine in a 2017 F250 with the 6.5’ bed and added a toolbox in front of it. Had to go with the in-bed box because my rv would have hit one of the boxes that sits on top of the bed. When backing up and turning my RV (Grand Design Reflection 307MKS) misses the cab by a good 3 inches. Installation of the mount rails that go under the bed was time consuming, not much room to use a wrench under there so each bolt took a while to tighten into place. The slider is big and heavy so it was a chore getting it dropped into the holes, I got 3 big guys to help out with that part. If I had to do it again I would not have done this install myself, I would have found a shop to do it prior to buying the RV. But I already bought the RV and could not wait for a shop to get it done. 556610

Love it. I like that it comes out and you get your bed back. If I had one thing to say bad on it is that when you back up to it you have to be lined up straight with it. You can't come in on an angle. But it's not the end of the world. It's great you don't have to get out in the rain to slide it back for the sharp turns. 591643

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.

Review from a similar Demco Hijacker Autoslide in Fifth Wheel


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

I have had this for a year now, It took a while to get comfortable hooking it up. but now I feel great about it. Works as described and I am more confident when making sharp turns in confined areas. 550075

Enjoy the new hitch , don't have to worry about hitting back of the cab anymore. I highly recommend if you have short box on your truck. You don't have to get out and pull a lever so it slide back, it does it automatically.. 308340

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

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

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

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

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

  • How to Tell if 2016 Chevy Silverado 2500 Has Factory Rail Kit for Fifth Wheel Hitch
  • Most likely you would know if you had the Factory Rail Kit in your 2016 Chevy Silverado 2500. There would be holes in the bed of your truck that the feet of a fifth wheel hitch would fit into. I attached a picture that shows what they pucks/holes would look like. If you have them the B and W Hitch part # BWRVK3700 that you referenced would fit and work well. Otherwise for an underbed fifth wheel hitch setup I would recommend the Demco Hijacker part # DM8550022 which will automatically...

  • Best Sliding Fifth Wheel Hitch Recommendation and Rail Kit for 2017 Ford F-350
  • The setup I would recommend is the Demco Hijacker Auto Slide part # DM8550022 with the rail kit part # DM8551009 for your 2017 Ford F-350 without the factory tow package. This is a slider hitch that will automatically slide back as you make tight turns which is a very nice feature as getting out and activating a slider mechanism can be a hassle. Especially in inclement weather. The rail kit mentioned is an underbed kit so your bed will be clean and free of large rails when you remove...

  • Demco Hijacker Auto Slide Hitch Weight
  • The head of the Demco Hijacker part # DM8550022 weighs 65 lbs. The total weight of the hitch with the head would be 289 lbs. You would need two people to get this hitch in and out or you could use the MaxxTow Crane part # MT70238 that is designed to install in the hitch of a truck.

  • Demco Hijacker Autoslide to Fit 2019 Ford F-350 with Factory 5th Wheel Prep Package
  • The Demco Hijacker Autoslide fifth wheel hitch you asked about, part # DM8550022, actually fits into an aftermarket underbed kit, part # DM8551009. It doesn't fit the OEM puck system you have in your new 2019 Ford F-350. Instead you want part # DM8550024 that does fit right onto the pucks. It's basically the same hitch except for how it mounts into the truck. I've linked a video of it going into a 2014 F-350. It's the same puck system as what you have.

  • 5th Wheel Trailer Hitch Recommendation for a 2017 GMC Sierra 2500 Short Bed w/Factory Prep Package
  • In order to use a Demco HiJacker auto-sliding 5th wheel trailer hitch with your 2017 GMC Sierra 2500 short bed and factory prep package you will need to use an adapter, # DM6194, because the hitches don't fit directly. With the adapter you can then use # DM8550034 as the proper version of the hitch for the adapter. Another option is to use B&W hitch # BWRVK3770 which fits directly in the GMC factory prep package without the need for an adapter. It is not an auto-sliding hitch though....

  • Puck System Availability for a 2017 Ford F-250 Super Duty with a 6-3/4 Bed

If the option to tow a gooseneck or 5th wheel trailer with a single underbed system is what you are looking for then a B&W Gooseneck Hitch is what you are wanting.
