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 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 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 (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.

It works Great



by:

Wow, where to begin. I can't imagine towing a 5th wheel trailer in a shorter bed truck without an autoslide setup. After the initial install I noted on the 2nd(?) trip a clunking noise during acceleration after a stop - a couple emails back and forth with Demco support, as well as a quick phone call, and it was all sorted out (user error) with no further issues - Thank you Demco!
I tow a short & light Jayco 5th wheel with a 1/2 ton shortbed and having the ability to drive, turn, and park the camper without having to get out of the truck to manually engage or disengage a slide on the hitch has made for much more relaxing weekends away. The Hijacker autoslide gives PLENTY of space between the camper and cab and I've never had to worry, but I did my homework and ran the numbers well before I purchased my hitch so I wasn't surprised.
I would say the only downside for me would be the weight and bulkiness of the hitch. Not having the means to easily remove and store it between trips, the hitch is forced to live in the bed of the truck right now, but I did know about the weight going into the purchase.
All in all, for the peace of mind the Demco autoslide gives me, I'd spend the money all over again.



by:

Hitch works great, my truck has a 5’7” box, I can back up turning 90 degrees if I need to. It’s very important that your pretty straight when you unhook or you can’t hookup. You have to be more accurate when hookup. The first few times it seemed like it was going to be a hassle, you just have to pay a little more attention. Hitch is worth it



by:

Your team was very helpful getting me the hitch that I needed, and it arrived a little sooner than expected. In fact my truck is still in the repair shop for the damage caused by the other hitch, so I have not installed the new one as of yet.
Thanks for all your help.



by:

Everyone that I spoke to on the phone were very helpful. I haven't hooked up my hitch yet but I like what I see so far.

Well built fifth wheel hitch. Haven't got a chance to tow our new Montana High Country 295RL. But I know a guy that has towed his fifth wheel with this same hitch. I'm sure this 18K hitch will be excellent! Or I wouldn't have bought it. I recommend e trailer for everything.



by:

Demco auto slide hitch works very well with my crew cab short bed Ram. Fits under my tonneau cover nicely. Trouble free thus far. Had to purchase a Demco plate for the camper to make the Rhino box hitch work. etrailer personnel were great in helping ensure I had the right products and kept me well informed of shipping dates.



by:

Well the Demco 5th wheel hitch is great! Great product, well built, great value! but, the delivery was terrible. I ordered the hitch on 8/10 and it didn't ship until 8/18! I was promised a delivery date of 8/17, but no one at e-trailer could find the hitch and did not get any answers from the shipping company. After many phone calls, they finally located the hitch with the shipping company, Estes, and the hitch was delivered on 8/22. I would use e-trailer again, but they need better control over the shipping.



by:

Item works exactly as described. I have a shortbed (6.5') Ford F350. Probably towed our 5th wheeler 5000+ miles with no problem. Then last year it happened! We were making a sharp turn in an uneven lot and POW, the 5vr hit the rear window and it exploded. After that I became gun shy about turning with the 5vr attached so I started looking at sliding hitches. A slider that you had to get out and unlatch to make work, didn't make sense to me. At what point do you get out? So, an auto slider hitch was purchased. Now when I get to a certain degree turn the auto-slide hitch moves back in its carriage and then auto-slides to the normal location once straightened out. Not gun shy anymore.

Pro:
Well packaged
Well made
Easy install
It WORKS.

Cons:
Price
Very heavy
Some clunking after it straightens out from a turn



by:

Very happy with my Demco Autoslide hitch after one year. We pull a Montana 3120 35 ft 5th wheel with a 2019 Ford F-350 short bed. Took a month long 6,000 mile trip from Colorado to New England/Canada this Summer. Lots of hilly/curvy roads and some remote campgrounds with tight corners and some near 80 degree back ins. Never came close to trailer contacting the truck. I’ve had no jerking or other issues when turning or stoping/starting. Works great. The only drawback is there isn’t much room for error when you back up to hook up the trailer, so it takes a little practice to get used to correctly lining up your Demco Hitch to the trailer. The first couple of trips, it took me 3 or 4 attempts to properly line it up. No longer an issue for me after a few trips and you get used to the angles. It weighs about 300 pounds. I got a small chain hoist which I installed in my garage rafters and easily lift the hitch in and out of my truck and just let it hang front he rafters until I need to use it.



by:

The Demco Auto slide takes the worry out of towing my fifth wheel trailer with a short bed F-350. I have had no problems with backing into tight camping spots. And since everything is automatic I have one less thing to worry about while traveling with a fifth wheel.
The only problem is that it is a little on the heavy side, so I just leave it in the truck when not towing. Problem solved.
I am extremely happy with the product.



by:

This was the best solution for my Dodge RAM 2500 towing my Alliance 340RL 38' 5th Wheel. My son helped me install the rails under the bed and now it is very easy to remove the hitch when I am not using it. It is very strong and I highly recommend this for anyone with a short bed truck.



by:

This hitch has worked great for the last year. I can put the truck a full 90 degrees to the camper with no issues on my standard bed (6'8") truck. I never have to worry about taking out my back window either going forward in tight turns or backing up. The only negative is the weight of the hitch. I use an electric hoist to take the hitch in and out of my truck. Very quick and easy with the OEM puck system. The guys at Etrailer were great to work with. Best price I could find and delivery was quick and easy.



by:

I have a F350 Super Duty Short bed.
This
slider works as expected. The ease of backing or tight turns makes this product excellent without the need to pulls pins for extension. I can remove or install in 7 minutes without a problem without any assistance. I am pulling a 44 foot trailer and have not experience any chucking or sway even in windy conditions. Tows very smoothly

This review is for the Demco Autoslide 21k and accompanying OEM rail adaptor I purchased for a 2020 Ram 3500 Megacab DRW. I've owned it one year. Overall, the hitch performs as I expected. It is high quality, very sturdy and seems like it will last for a long time. I had it installed at the dealer when I purchased the truck. It automatically slides to protect the cab in my 6'4" bed without any incidents. I tow a standard fifth wheel RV. There are a few negatives, which are not necessarily shortcoming of the product but, instead, necessary evils to allow me to have a short bed. First, it is BIG and BULKY. I believe this is just a function of the mechanism required to allow the autosliding feature and I am not really sure there are any other lighter alternatives with this feature. The fact it requires two parts (OEM Puck Rail and hitch), make it even more bulky. It takes up almost the entire bed and prevents most auxillary tank / tool box combos from fitting. Even standard size storage bins will not fit in my bed. I would prefer if they had a custom OEM all-in-one hitch for my truck like they do for the Ford. It adds significant weight, which decreases carrying capacity, which can be at a premium in hauling a heavy fifth wheel. I've never even tried to take it out of the bed due to the weight and difficulty. I also am not very happy with the adjustable catch plate design. It requires significant manipulation loosening and tightening 8 nuts when hitching and unhitching. This requires a step ladder to reach the nuts. I also found out after the fact that it does not come with the right size catch plate attachments for my hitch and I had to purchase a separate part, which added unexpected expense and delayed my taking the RV on its first trip. Overall, I am satisfied with the hitch.

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



by:

Very high quality product. Used on a extended cab short bed F250 and the sliding mechanism provides plenty of clearance between the Fifth Wheel front and the truck's cab. Fits Ford's factory fifth wheel bed mount holes perfectly. Used to tow a 42' fifth wheel regularly. Foot print is small enough to allow me to retain my tool box in the truck during towing.

The hitch is heavy! Do not plan to try to install with one person with out an engine hoist or gantry crane. Two strong people can, but extreme caution should be taken as the hitch weighs nearly 300lbs and is awkward.



by:

I have a 2017 Ford F-250 (Crew Cab, short box), and a 40’ 14,000lb 5th wheel. I’ve owned this Demco Autoslide for 1 year, and I absolutely love it. I purchased a 5th wheel for the maneuverability, but my expectations were blown away with this Autoslide. I also have the Extang Xceed hard tonneau cover, and when folded up (laying flat on the panel closest to the cab) I can maneuver however I want without removing the tonneau. If im going to make a really sharp turn on uneven ground I’ll stop and flip my tonneau all the way up, but very rarely do I have to do that. Also removal & install of this hitch is about as easy as removing & installing a 5th wheel hitch can possibly be. I use a rope, pulley, & my side by side. Highly recommend this Demco hitch.



by:

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.



by:

wow what a great hitch . Got the no drill bed rails and the bolted rite up to my B&W gooseneck hitch . Ashley E did a great job answering all my questions . Only took a few days to get here too. Took me about 2 hours to install everything and if you have a short bed truck this is the only way to go .



by:

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.

  • Is There Version of Demco Hijacker Autoslide 13k That Fits Ford OEM Rail Kits
    There isn't a version of the 13k Demco Hijacker Autoslide part # DM8550040 that fits the Ford puck system since it is a hitch designed for 5-1/2 beds and there isn't a version of a Ford truck that would have that bed length and the puck system. The F-150 does not have the option for the pucks. This hitch also cannot be used with a Sidewinder since the Sidewinders pivot on a locked hitch head and the heads of the Demco Hijacker Autoslides pivot as well.

  • Should Head of Demco Hijacker Autoslide Turn by Hand
    Turning the head of a Demco Hijacker Autoslide like the part # DM8550040 is normally too difficult to turn by hand unless the hitch has quite few miles on it since that loosens up the clearances a bit. There isn't a recommended way to straighten it by hand or by disassembly so best option would be to make sure you are totally straight when connecting and disconnecting.

  • Sliding Fifth Wheel Hitch Recommendation for Truck with 5-1/2 Foot Bed Length
    There's only one slider hitch that can work in a bed length shorter than 6 feet and still provide enough turning clearance and it's not one made by Reese. Instead you'd want the Demco Hijacker Autoslide hitch part # DM8550040 which will automatically slide back and give you 22-1/2 inches of clearance. This would basically be the only sliding hitch that's going to work for your application.

  • Fifth Wheel Hitch Recommendation for Needing 15 inches of Turning Clearance
    Since the RBW 7027 is a tube style pin box there isn't a Sidewinder pin box that will give you the turning clearance you'd need, but we do have one fifth wheel hitch that will slide more than 15 inches like you'd need. The Demco Hijacker 13k part # DM8550040 might be ideal for you. As you make tight turns it automatically slides back 22-1/2 inches to give you the clearance you need for sharp turns. This way you don't have to remember to activate the slider as you enter and leave parking lots.

    If your truck bed is really 5-1/2 feet in length you are going to have to use the one slider hitch we offer that can slide back 22-1/2 inches, # DM8550040, or replace the pin box of the trailer with a Sidewinder. However there is a formula you can use that will tell you the final answer on whether or not you can use a stationary hitch. But it requires you taking a few measurements. You'll need to know the distance from the axle center of your truck (that's where the king pin will be) to...

  • Does Truck and 5th Wheel Trailer Need to Be Straight to Connect to Demco Hijacker Autoslide
    Yes, when you go to hook or unhook from a fifth wheel trailer using the Demco Hijacker Autoslide hitch like the part # DM8550040 you have to be almost perfeclty straight otherwise it won't work. This is because the auto slide mechanism activates when the head is turned.

  • Can a Ford F-150 with a 5-1/2 foot Bed Tow Fifth Wheel Trailer and Have Turning Clearance
    For a 5-1/2 foot bed there really is only two options for towing a fifth wheel trailer to allow you the turning clearance you need. But you have to install the rail kit where it's intended to be, right above the center of the rear axle for proper weight distribution. The best way to tow a trailer for you would be with a Sidewinder pin box as they give you 22 inches of additional turning clearance. You will need to remove the pin box of the trailer and replace it with a Sidewinder pin...

  • Demco Hijacker Autoslide Fifth Wheel Hitch Recommendation for 2016 Ram 1500 5.5 foot Bed
    For a truck with a 5-1/2 foot long bed the Demco Hijacker Autoslide hitch part # DM8550040 that you referenced would be perfect. Unlike most slider hitches this one slides 22-1/2 inches which would be enough to allow your truck to make a tight turn. For a set of above bed rails confirmed to fit your 2016 Ram 1500 we have the Reese kit part # RP50142-58 that would be your best option. These rails are custom fit to your truck bed which means they will install in much less time than a universal...

  • Recommended Sliding Hitch for 200 AlpenLite and Short Bed Truck
    We do not have a replacement pin box for the Atwood AB-72 from any of our manufacturers. Reese used to make one but they discontinued it. It didn't give any extra length to the pin box, it just added a suspension component. You will need to utilize a good sliding 5th wheel hitch to give you the turning clearance you desire. Based on the GVWR of your trailer, I recommend the Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider - Single Jaw - Above Bed - 13,000 lbs # DM8550040 which...

  • Demco Slider Hitch Recommendation for 5-1/2 foot Bed 2015 Nissan Titan
    Since your truck bed is 5-1/2 feet long you would have to use the 13k Demco Hijacker # DM6141. This is the head and base assembly that will bolt up to the current mounting assemblies that you have on your 18 Hijacker. This head assembly will slide 22-1/2 inches which will give you the needed clearance to make tight turns. If your plan is to resell the hitch though you might be better off just selling the whole assembly and getting the # DM8550040 since it may be easier to sell a complete...

  • Fifth Wheel Hitch Solution for Truck with Short Bed
    Since you said you have a short bed that means you need a slider hitch. My favorite slider hitch is the automatic sliding hitch by Demco part # DM8550034. Unlike most sliding hitches that require you to get out and activate the slider mechanism every time you need to make a sharp turn this one slides automatically as you make the turn. This will work great on truck beds that are larger than 6 feet. This hitch has an 18k capacity. If you have a bed length that is shorter than 6 feet you...

  • Recommended Demco Auto-Slide 5th Wheel Hitch for 2017 Ram 2500 Laramie 4x4 with Factory Prep Kit
    I recommend using a 5th wheel slider hitch with as much travel as possible to increase your turning clearance and minimize risk of contact between the trailer overhang and your headache rack/boat.
