Automatic Slider Makes Cornering Easy

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 22-1/2" 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.


The Autoslide has a built-in roller-and-guide assembly that allows for smooth, controlled, and automatic movement. As your truck turns, this assembly also turns. When the assembly turns, an arm in the base of the hitch moves down 1 of 2 tracks in the interior of the base. This action causes the head to be pushed down one of the exterior tracks in the base. So, when your truck makes a sharp, slow-speed turn, the roller-and guide assembly inside the Autoslide forces 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 roller-and-guide assembly to function as designed, the pin box must be stabilized on the hitch head. Normally in a 5th-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.


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 (22-1/2")

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 - DM8550041 Review

Today we're going to take a look at the Demco Single Jaw Hijacker Auto Slide fifth wheel trailer hitch with the slider. This is for the under bed mount and this has a thirteen thousand bound weight capacity. This fifth wheel hitch will mount in your short bed truck bed so that you can tow your fifth wheel trailer. It is an automatic slider which will provide clearance that's required for your short bed truck to turn safely at slow speeds, and there's no more getting into and out of your truck to operate a manual slider. This head will slide toward the tailgate when you turn and then back toward the cab when you straighten out. On the underneath here, it uses a roller and guide assembly which will create a nice smooth and controlled movement. Basically on a fifth wheel when you hook up your pin box, usually when you do your turning your kingpin would be spinning, the pin box would turn.

What this basically does is it would hold your pin box secure from turning and the actual hitch head would turn. Basically what happens is if you're towing and your trailer's straight behind you, it will stay in this position closest to the cab. When you get into a position where you're going to do some sharp turns, what'll happen as is you turn, once this turns to about ten to fifteen degrees then it'll start automatically sliding towards the back tailgate to get you that extra clearance that'll be needed. When you straighten out it'll slide back up and lock into the straight ahead position. What happens is when it rotates it creates that force that'll move that automatic slider back. It does have these built in brackets right up here on the hitch head. These are to stabilize your pin box so the kingpin won't rotate.

There's no need for separate capture plates on a standard cushioned, non-cushioned pin box. What happens is, you see these two bolts and nuts right here You just loosen those, loosen the jam nut and then back the bolt out and you can adjust these bars in or out. It'll range anywhere from twelve inches wide up to fourteen inches wide for a standard pin box. Once your pin box gets in there and your kingpin's all hooked up, just bring these out to the pin box and then tighten your bolt down to hold it. Then take the jam nut and tighten that up. It'll hold it in that position so it doesn't move.

This head does use a wrap around, single piece jaw which would provide a secure connection. It gives you a three hundred and sixty degree jaw to kingpin contact, and because of that it'll give you less rattle and more security than the slide bar jaws. If you notice on the front there's a very thick three quarter inch think solid steel locking bar and that's to reinforce the connection of your coupled trailer. Once the jaw goes around the kingpin, this solid steel locking bar will automatically lock into place when the jaw closes. The hitch head is a double pivot hitch head. It eases hook up, helps limit chucking, pivots front to back and it also goes side to side. This part will come with the side plates.

I've already installed them on to the hitch base for the under bed mounts and they have three height settings. There's three rows of holes in the plate, and two rows of holes in the hitch base, so it'll line you up. It'll give you three height settings from fifteen and a half inches, sixteen and three quarters and eighteen and one quarter are your three choices so you can get it close to get your trailer and tow vehicles as level as possible, which is what you want to do. Again, these are for the under bed mounts so it has the . basically what it is is they're designed to fit in the mounts that are under your bed. If you just pull this clip off you can see you rotate that lever ninety degrees. Do it on each . at one here, one over there, and one over there. Then that'll drop into the under bed mounts. Once they drop in, just turn it back to ninety degrees. It'll lock those tabs in there and then to secure the handle, just drop your pin through and then take your clip and clip it just like that. That'll hold it into place. You do that on all four corners. It does use cushioned polyurethane dampers underneath here to help reduce noise and absorb road shock. The handle is a spring loaded handle. It has a nice comfort grip to allow for simple coupling. It has this tethered safety pin, and when you remove it it'll stay tethered so you don't lose it, and it'll let you secure the handle in the open or the closed position. This whole part is a sturdy steel construction. It has a nice rust resistant black powder coat finish over all the parts. It does also come with . I want to mention this adjustable outrigger bar right up here at the front. This outrigger bar is designed to help carry and distribute the hitch and trailer weight when that hitch is at its full travel distance, all the way towards the tailgate. This is a very simple installation. Just use your base rails and installation kit. If you do need those, we do sell those separately on our website. It is compatible to fit the B and W, Curt, Demco, Draw-Tite, Hidden Hitch, Husky, Reese, Valley, all the above bed base rails. This part is made in the USA. The specs on this, it's designed for use on five and a half foot and six foot truck beds. It's designed to fit standard pin boxes, twelve inches up to fourteen inches wide. Now, if you do use a cushioned pin box on your trailer like the Glide Ride, the MORryde, the Trailair Tri Glide and the fifth Airborne, with those it does require locking plates. They are required to lock those into position. Those we do sell separately on our website. Gross towing weight capacity on this is thirteen thousand pounds. Vertical load limit, or pin weight capacity, is three thousand two hundred and fifty pounds. The amount of travel front to back is twenty two and a half inches. We mentioned the hitch height, fifteen and a half inches, sixteen and three quarter and eighteen and one quarter hitch height adjustment. What I'm going to show you right now, I have an example of a kingpin right here. I'll show you how it connects in to the hitch head. Just pop off that pinning clip. That'll release your handle. Just take your handle, and it's spring loaded so when you pull it all the way out, you can see it locks the jaw open. It's ready to hook up, so when you're backing up to couple you can see the kingpin will slide right in. Once it gets in far enough, it'll trigger that jaw to completely wrap around that kingpin. The handle comes back, lines up. That bar is locking it all into place and all you have to do is take your pinning clip, drop it right through the hole there, clip it and you're all ready to go. Simple as that. That should do it for the review of the Demco Single Jaw Hijacker Auto Slide fifth wheel trailer hitch with slider for under bed mount, and a thirteen thousand pound weight capacity.

The hitch is great. I installed it myself and it worked very well pulling a 5th Wheel Trailer across the country last year. I have learned however that one must start out from corners slower to avoid a large "clunk" as the hitch slides in the frame per the inherent design. Great Product! 486223


Comments
Im very happy with the hitch. Ive towed for close to 15,000 miles. I did however travel over one very uneven road and cracked a weld on the adjustable side guide on the top plate. Great hitch!

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


Had this for a year. Works very well. A bit heavy to remove but worth the confidence knowing this hitch is built heavy duty. Also not having my truck damaged is priceless. There is a routine that needs to be followed to lock in side rails. I put magnets on each side with a wrench on a tether so that I just reach down a grab the wrench for each side. Keep in mind, you need to back straight to hook up. Not designed to back in on a angle. That all being said, very pleased with this hitch and the great customer service from etrailer 636621

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

Ask the Experts about this Demco Fifth Wheel

  • Is Demco Hijacker Autoslide Compatible with MOR/ryde Pin Box
    Yes, the Demco Hijacker Autoslide 5th Wheel Trailer Hitch # DM8550041 referenced in your question is compatible with the MOR/ryde pin boxes. You will just need to add the Locking Plate # DM6025. This locking plate is designed specifically for the MOR/ryde pin box and will bolt to it in order to prevent the king pin from rotating inside the Demco Hijacker. All of the necessary hardware is included. I have attached the installation instructions on this product that you can also take a look at.

  • Does Fifth Wheel Hitch King Pin have to Center Over Rear Axle of Truck
    The center of the king pin of a fift wheel trailer needs to be centered over the rear axle. Since fifth wheel trailers are pretty heavy if you had the pin weight behind the rear axle you'd unload the front axle which would make braking and handling dangerous. I believe you have a 2005 Ford F-150 with a 5-1/2 foot bed. For bed this short there's one slider hitch that can slide far enough back to give you the needed turning clearance and it's the Demco hijacker auto slide part # DM8550041....

  • Recommended Fifth Wheel Hitch For 2010 Ford F-150 With 5-1/2 Ft Truck bed
    There are two ways you can go when towing your fifth wheel with your short bed F-150. You can go with a fixed fifth wheel hitch and replace your fifth wheel pin box with a Sidewinder, or go with a sliding fifth wheel hitch like the Demco Hijacker Autoslide 5th Wheel Trailer Hitch, part # DM8550041, along with the custom underbed rail and installation kit, part # DM8551001. This will give you 22-1/2 inches of front to aft travel and allow you to make those sharp turns. The great thing...

  • Will Demco 13k Autoslide Hitch Allow for Turning Clearance in 5-1/2 foot Truck Bed
    The Demco 13k Auto Slider part # DM8550041 will automatically slide up to 22-1/2 inches as you make tight turns. That's substantially more than other slider hitches and it's currently the only slider hitch we can recommend for a truck with a 5-1/2 foot bed like I am assuming you have. There is a formula that you can use if you want to be cautious though. (A + B) - C = Clearance A = Distance from the fifth wheel jaw center to the truck cab (you can use rear axle center) B = Slider distance...

  • Will the 13K Demco Autoslide # DM8550041 Work with a 2018 Ford F-250 6-3/4' Bed
    Yes, the Demco Hijacker Autoslide 5th Wheel Trailer Hitch # DM8550041 is compatible with your 2018 Ford F-250 with a 6-3/4' bed. This hitch actually installs in the Demco Underbed Rail and Installation Kit # DM8551009 instead of a traditional "OEM prep package". If you don't already have a 7-Way in the bed of your F-250 then I also recommend the Demco # DM8555002 which help make connecting and disconnecting the wiring in your pickup much easier.

  • Slider Hitch Recommendation for 2013 Ford F-150 5-1/2 foot Bed
    For 5-1/2 foot beds there is only one slider hitch we offer that slides far enough to allow turning clearance. That would be the Demco Hijacker part # DM8550041 as it slides 22-1/2 inches and the hitch you referenced only slides 12. For a rail kit that is custom fit for your 2013 Ford F-150 with a 5-1/2 foot bed and the Demco we have the # DM8551001 which would be what you would need.

  • Recommended Best 5th Wheel Hitch for 2017 GMC Sierra 1500 5-1/2 Foot Bed
    The best hitch for your 2017 GMC 1500 Denali is really based on preferences. My recommendation for the best is the Demco Hijacker Autoslide # DM8550041 with the Underbed rail kit # DM8551008 because it gives you a completely clean bed when not in use and then provides you with a hitch that has 22-1/2 inches of travel that automatically moves as needed to give you the turning clearance needed. I've attached a video of this hitch installed in a 2017 Chevy 1500 to assist. The biggest benefit...

  • 5th Wheel Hitch for 2014 Ram 3500 Short Bed with RamBox
    I'll start off by saying that because your 2014 Ram 3500 has the Ram Box cargo management feature, you will need to use a Sidewinder King Pin. The problem with the Ram Box is that is that it puts the rails of the bed too close together and it causes interference with the pin box of the trailer around corners. We have heard several customers say that with a Sidewinder pin box they were able to tow a fifth wheel trailer with a truck with a Ram Box. Sidewinders move the pivot point higher...

  • How to Tow a 5th Wheel Trailer with a 2017 Chevrolet Silverado 1500 that has a 5-1/2 Foot Bed
    I have attached the formula that is used to determine turning clearance with a 5th wheel trailer for you below. In order to give you the exact measurement you are looking for we would need to know the distance from center of fifth wheel hitch jaw to the truck cab. However, I can already tell you that you will need to use either a rotating pin box or sliding 5th wheel hitch with at least 22-1/2" of travel in order to execute a 90 degree turn with your 2017 Chevrolet Silverado 1500 because...

    For the 2012 Ford F150 with a 5.5 bed, I recommend the Underbed Rail and Installation Kit for Demco Hijacker UMS 5th Wheel and Gooseneck Trailer Hitches # DM8551001 and the Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider - Single Jaw - Under Bed - 13,000 lbs # DM8550041. This is the only system that does not require you to change your pin box out for a Sidewinder. No other sliding hitch will be compatible, but this system automatically slides to provide you with proper clearance...

  • Fifth Wheel Hitch Recommendation for 2007 Ford F-150 5-1/2 ft Bed
    A truck bed that is only 5-1/2 feet in length needs more slider clearance than what a standard slider hitch like the Curt E16 you mentioned can provide. You'll need around 22-1/2 inches of additional clearance and this hitch only provides 12 inches. We have one hitch setup that will work great for that though. The Demco Hijacker 13k Autoslider part # DM8550041 slides back 22-1/2 inches automatically as you make tight turns. To install it in your truck bed will require an underbed rail...

That's the Demco Hijacker Autoslide part # DM8550041 which will slide back 22-1/2 inches automatically as you make tight turns so that you have the needed turning clearance. Then for a rail kit to install this hitch you'll need the Demco rail kit part # DM8551001 which is a custom kit for your 2004 Ford F-150. This means it will install without frame drilling...

  • Determining Pin Weight for 8k Trailer and Fifth Wheel Hitch Recommendation for 2014 Ford F-150
    There is not an easy way to verify the tongue weight of a fifth wheel trailer if you do not already have the trailer. The best way to find the tongue weight of your fifth wheel trailer is to use a commercial scale like those at truck stops or at material supply centers. First you should weigh your tow vehicle without the trailer connected. Next, connect your trailer to your tow vehicle and drive it on the scale. The difference between the two weights is the tongue weight. Since you...

  • Fifth Wheel Hitch and Rail Kit Recommendation for 2015 Ford F-150 5-1/2 foot bed
    For a truck with a bed shorter than 6 feet the fifth wheel hitch options are a bit limited as that's not a lot of room to work with for coming up with a way for the trailer to be able to have turning clearance. We only have one slider hitch that can give enough clearance for tight turns and thats the Demco Hijacker 13k AutoSlide part # DM8550041. This hitch can slide 22-1/2 inches. For a rail kit you then would want the Reese Custom install kit part # RP56034-53 which is a custom...

  • Under Bed Mount Fifth Wheel Rail Kit and Hitch Recommendation for 2011 Ford F-150 5-1/2 ft Bed
    An underbed mount fifth wheel rail kit will not reuse the same holes in the bed of your truck as a set of above-the-bed rails would have used in your truck. The holes would either need to be patched or left as-is. Since you have a 5-1/2 foot bed 2011 Ford F-150 the best solution we have is the part # DM8550041 which is a sliding fifth wheel hitch that automatically slides back as you make tight turns and unlike most sliding hitches it actually slides back far enough for how short your...

    In order to use the Demco 13K HiJacker # DM8550041 you will need the proper under bed installation kit for your 2014 Ford F-150 with 5-1/2 foot bed. The installation kit needed is # DM8551001. No other parts are required but I do recommend installing an in bed 7-Way, # 41157, to make hooking up the trailer easier without having to use extensions.

This particular hitch is not compatible with the Revolution king pin on your trailer. I instead recommend looking at the Reese Select Plus 5th Wheel Trailer Hitch # RP30081, along with the Quick-Install Custom Base Rails # RP50064-58. This is an excellent hitch that features a forged, single-piece self-latching jaw that will provide...

  • Is Capture Plate Needed to Use Demco Hijacker Autoslide with Jayco Eagle HTX

The confirmed fit for your truck is the Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider - 18,000 lbs # DM8550034 or the 21K # DM8550035. Either will work well with the Rail adapter for Ram 5th Wheel Towing Prep Package # DM6099 or the Reese 5th Wheel Rail Adapter # RP30154. The weight of the hitch is 273 lbs for the 18K and...

  • Best 5th Wheel Trailer Hitch for Turning Clearance for a 2015 GMC Sierra 1500 Short Bed
    There are a couple of ways you can get increased clearance between the truck cab and the 5th wheel trailer when making tight turns. In your picture it doesn't look like you have a hitch yet so the most cost effective solution is going to be a sliding 5th wheel hitch. I recommend a Demco HiJacker auto-sliding hitch. That way you don't have to get in and out of the truck to operate the sliding mechanism. I assume that your 2015 GMC Sierra 1500 is a short bed but it is the really short...

This will add weight to your truck, but it's minor compared to the weight the hitch is capable of towing.

  • Gooseneck and 5th Wheel Hitches with Offset to Tow a Trailer with a 2012 Ford F-150 w/5-1/2 Foot Bed
    If you are towing both 5th wheel and gooseneck trailers then what I recommend for the gooseneck trailers is B&W gooseneck hitch # BWGNRK1104. Then you could add the 4 inch offset ball, # BWGNXA4085, and the 10 inch Extend-A-Goose coupler, # BWTEXA4200. However, the pivot point of the trailer will still only be 4 inches back from its original position meaning that you will get 4 inches of true offset, not 14. If your gooseneck trailer is a V-nose then the 4 inches might be enough to...

If this is the case, then you can use the Demco Base Rails Adapter, part # DM6140. This adapter installs into the B&W Gooseneck to provide industry standard base rails. Since you have an 8 foot bed now, your pivot point will be further back naturally, so a sliding hitch won't matter...
