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 designed to attach to universal above-bed base rails (sold separately). The hitch will fit most industry-standard rails, including those from B&W, Curt, Demco, Draw-Tite, Hidden Hitch, Husky, Reese, and Valley. 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 your above-bed rails, 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 attach the base to the rails with the included safety pins.


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 - DM8550035 Review

Today, we're going to review part number DM8550035. This is the Demco 21,000 Pound Hijacker Autoslide Above Bed Mount 5th Wheel Hitch. Now, this hijacker autoslide is an automatic sliding 5th wheel hitch. It is designed for sharp bed trucks with a 6.5 foot bed to give you additional clearance between your truck's cab and the trailer during turning maneuvers, and it does eliminate the needs to have to get in and out of the truck, pull a pin, and manually slide the hitch back and forth. This will automatically slide by using a rack and pinion gear technology right here in the base of the hitch. It will move about up to 14 inches of travel fore and aft to help you get in and out of those tight spots. Now, normally on a 5th wheel trailer, when it connects to the 5th wheel hitch, it is designed to lock into place and pivot on the kingpin, right where it's connected to the hitch head and the jaw there, so the pin box made to move like this. On this hitch, it actually locks the pin box in, and lets the hitch head itself do the rotating.

Has this integrated locking system right here in the head to lock your pin box in place on the hitch head, and that eliminates the need for any additional locking wedges with a standard pin box. Instead, your hitch head will totally pivot with the pin box locked in place, and, if necessary, if it gets to about a 10 to 15 degree turn, it will also automatically get closer to the tailgate, which'll create more space between your truck cab and your trailer on sharp turns. Now, with it in this position, if you're towing it and the trailer's directly behind you and you're not turning, it will not move on its own back because there is a guide plate that holds it into place. It does have to get to about a 10 or 15 degree angle, then it would automatically move back if needed. Now, this autoslide hitch is designed to work with standard trailer pin boxes between a 12 inch minimum width up to a 14 inch maximum width. They have these capture plates you can see right here on the head, and these are adjusted to the width of the trailer pin box in order for this automatic slide mechanism to operate properly. So basically, what happens is with the trailer backed in and all hooked up, what you would do is you'll see these capture plates can move in and out on each side.

What you'll want to do is, once your pin box is all installed, push this up against your pin box, and then with the bolts right here, just finger tighten these bolts all the way down. You'll do both of them, and then on this side also. Then once they're tightened down, run these jam nuts up to lock them into place, and that'll keep them from moving, and this will keep your pin box from rotating on the hitch head. Allows the hitch head to do the movement, or the pivoting. Now, one thing I do want to mention, that if this hitch is installed in any trucks with like a 5.5 foot or a 6 foot bed, there is no guarantee that you'll get a full 90 degree turn with this autoslide hitch. Now, this autoslide hitch is designed for use with RV-style 5th wheel trailers that use an industry standard 2 inch diameter kingpin.

This does have a 21,000 pound towing capacity. It is a lower profile design, which helps as far as easy access for routine maintenance on it. One of the nice things that's easy to do is these jaw pins right here, they're pushed down in. You can unsnap the snap ring, pull these out, grease them up, put them back in, put the snap ring on. Makes it very easy to grease these jaw pins. This is a lighter weight hitch for easier hitch installation and removal.

One of the other nice features is if you need to take this out of your truck bed, you can just pull the clip down here below the head, pull the long pin out, about this long, and that's what keeps the head into the saddle. Once you pull that pin and clip out, you can lift that head out of the saddle by yourself, and then it makes the base even lighter to help you remove it if you don't need to tow. Now, this does feature a double pivot head, and by double pivot, we mean it goes side-to-side, and it also goes front-to-back. It does have a wraparound jaw, which'll totally wrap around the kingpin when it's installed, and in front has a nice locking bar for a smooth, safer, and more secure ride. Now, this autoslide 5th wheel hitch will come assembled from the factory to help make your installation easier and quicker. The only thing you'll have to do is add these. They do come with them. You'll just have to add the side plates to the hitch and put them in the correct hitch height position. Again, they are included. You just have to mount them in the correct position. That's the only thing. These side plates are what will connect your hitch to the rails in the above bed rails. They have the tabs in them. What you'll need to do is you'll notice on these side plates, there's 3 rows of holes, and then on hitch itself there's 2 rows, so you can move them up or down to get your 3 different vertical height adjustments to help you level your truck or trailer. Basically, the lower measurement would be 16.5 inches, and that measurement, when they say hitch height measurement, it's from the truck be to the top of the hitch head. At the lowest, it would get you 16.5 inches. The middle would be 17 and 3/4. The highest would be 19 and 1/4. So you can get it for your correct application. Now, one other thing I want to show you on here . Now, on these side plates, they will come with the pins and clips that I show here, and that's what's used once this is dropped into the rails. You run your pin and clip through to lock it into place. I also want to mention this outrigger bar right here up in the front. I have that attached with the long bolts net. That is used to help carry and distribute the hitch and trailer weight when the hitch is at its full travel distance. It'll help eliminate any movement of the hitch in the truck bed. What you need to do is adjust that after your hitch is installed and at its correct height in the truck bed and just tighten that down. Now, this hitch is made in the USA. It's made with American steel. I do want to show you how this jaw would operate. Got an example here for demonstration purposes. We have a demonstration. Here's a 2 inch diameter kingpin, like would be on your pin box, so what you'd want to do is first pull the pin and clip out. Pull your handle completely open, it locks into ready-to-couple position. And then again, this would be your pin box, for when you'd be backing up, your kingpin would be sliding in. Once it slides in far enough, it would automatically wrap the jaw around it to lock it in place, and then the locking bar slides also to keep it secure. And then before you're ready to get on the road, you just want to put your pin and clip back in so you know the handle's secure and everything's in place. That should do it for the review on part number DM8550035, the Demco 21,000 Pound Hijacker Autoslide Above Bed Mount 5th Wheel Hitch. .

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

I had trouble with this hitch at first. I could not get it to close and latch properly when I backed into the king pin. I worked with tech services and ended up replacing the inner pivot parts and I have really not had any issues since. Because I have to have the locking plate for my pin box, you do have to line up the truck just right for it to latch properly, but once you figure that out, it is easy. The auto slide feature works really good. I have a short bed RAM truck and I have completely turned 90 degrees with my trailer attached and it slides back with no issues to miss my cab. I highly recommend this hitch. Also the Demco Tech Services guys are great to work with. 338908

Great hitch. No capture plate to deal with, you can hook up to any 5th wheel. No more greasy pin box. No more watching the mirror wondering if your going to hit and damage the cab of your truck. Works perfectly. Built solid, though I did purchase the 21K for a 15K 5th wheel. Easy to lube. The only drawback I had was that it sat just a little bit high in the truck even on the lowest mounting holes. If you are thinking of purchasing this you may want to take some measurements first. I have an 08' F350 SD with air springs so it does set high. Before I bought it I called the factory (easy to reach and eager to help) and asked them, among other things," if the hitch broke, could I easily get parts for it?" They replied that if you need parts we will get them to you wherever you are. Overall I think this is the best hitch on the market. 446202


Comments

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.

Very happy with the product. The only draw back is the weight. Can't be loaded/unloaded by one person. A good cross-sell opportunity is to offer a tool for removal. When I first got it, it didn't fit the truck. Support team was helpful and responsive. It seemed to be due to the bed spray. I was able to get it to mount perfectly by loosening a bolt under the truck, and then smoothing the edges of the locks in the rails. 352378

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

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

$46.36
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.

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

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

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

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

I have found a way to improve hitching up on uneaven ground by increasing the height on the adjustable alignment guides on the sides. I love my hitch and the tec suport I receive when I need help. How do I share a picture?

I like the fact that I do not have to remember to slide the hitch. I wish I could manually slide so that when I back up my steep drive, I could assure no interference between truck and trailer. Ford mounting works great. 250562
