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 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, Rota Flex, Lippert Road Armor, 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 mount to the included industry-standard base rails, which install in your truck bed and are anchored to the included custom brackets that attach to your vehicle's frame. 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 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 Autoslide 5th Wheel Trailer Hitch for Nissan Titan Review

Jeff Hello, everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at the replacement side plates for the Demco Hijacker Autoslide above bed mount fifth wheel trailer hitches. Now these will replace the side plates that came standard on your Demco Hijacker Autoslide above bed fifth wheel trailer hitches. It is designed to fit the Demco 13,000 pound, part number D-M-8-5-5-0-0-4-0 model. Fits the 18,000 model, part number D-M-8-5-5-0-0-3-4.

And it also fits the Demco 21,000 pound model, D-M-8-5-5-0-0-3-5. All three of those models we do sell separately on our website. Now when these side plates are attached to your Autoslide assembly it'll allow you to install your fifth wheel hitch in to your universal above bed base rails. These are a simple bolt on installation tier hitch base. You can see it does have multiple rows of bolt holes.

And the reason they do that is it let's you adjust your hitch height that you need for your application. It'll give you three different hitch height settings. Either 15 1/4 inches, 16 1/2 inches, or 18 inches. And the hitch height is critical because you wanna be able when you're towing your fifth wheel to be as level as possible. And the hitch height is always measured from the bottom of the truck bed to the top of the hitch head.

Now the finish on these, they have a nice rust resistant black powder coat finish on them. It is a steel construction. Does include everything shown here. Includes all the mounting hardware. All the pins and clips that'll attach it to your base rails.

And the nice set of instructions that'll describe how these install. And how it operates. But that should do it for your review on the replacement side plates for the Demco Hijacker Autoslide above bed mount fifth wheel trailer hitches..


by:

The new lower base for the Demco hitch arrived on Tuesday via Freight it was a great interaction the driver I actually knew from a previous delivery, me and a friend were able to lift the old one out of the bed of my truck and install the new one today and all I have to say is...

PERFECT FIT!

It appears that Demco has already redesigned the lower base compared to my original one to prevent this problem from happening again. I was actually kind of shocked to see that upgrade and change.


I cannot say enough good words about you with etrailer and Demco working with me to get this problem solvedm Yes it took a little bit of work, ultimately this time we got it. I cannot thank you guys enough.

My friend and I will be finalizing the installation and getting it locked down to the bed with a few custom spacers for the lower rails this weekend.

Here are a few pictures of the installation resuming. If I remember , when I finally pick up my new camper, I'll send some pictures along too. Have to give credit where credit is due . Not sure of you have a customer wall at HQ. I know we had one in my old shop.

Anyway.. thank you again .



by:

Has to do a little assembly, really easy. Tows super nice, when turning does move towards the back. You’ll need to adjust the guides for the fifth wheel.



by:

Installation was straight forward operates very smooth and quiet installed overhead winch as seen in photo to make install easy also to remove very impressed with the craftsmanship of hitch.



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:

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:

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.



by:

Installed in my 2014 Silverado. This looks to be a very heavy-duty hitch that doesn't require a capture plate.



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 love this hitch. Never having used an automatic slider and moving from a long bed to a short bed truck it took me a few attempts to get accustomed to backing up.
I would recommend this slider over any other brand. No capture plate needed either.



by:

Excellent choice for a short bed Super Duty . Have towed several thousand miles with no issues. This is a heavy hitch , but that is what you get with a heavy duty Demco hitch . Plenty of room between trailer and truck when doing tight turns.



by:

Tows great. I’m a first time fifth wheel owner. This made it easy. Be careful because this hitch is capable of angle that your trailer axles aren’t especially on a hard surface like asphalt or concrete. Over all very pleased. Be prepared to hoist this hitch in and out of your truck if you plan on removing it often. Probably weights closed to 400-500 lbs.



by:

Unit is heavy and well built. Install was easy, just bolt on side plates on, drop the base on the adapter plate and pin it, put head assembly on and pin that, that's all there is to it. Looking forward to many years of towing with this unit.



by:

Really enjoy the Demco Hijacker autosli de.



by:

This was a huge improvement over my last hitch. This hitch took away the most of the jerking and bouncing I had before. Easy to install though pretty heavy. It also took away the fear of hitting my cab with the trailer every time I had to make a sharp turn and knocking out my back window again. Those of you that have the aluminum body Fords, beware, the cab won't take much abuse as the older steel body did.

Demco fifth wheel hitch purchase and installation pictures.




by:

This slider works great never have to even think about it being back there it does it's job with out a care from me worth evert penny it cost.



by:

Works like a charm



by:

We absolutely love our Demco Hijacker auto-slider hitch. We have a 6.5 ft bed, and a rather large 5th-wheel. I never have to give a single thought to unlocking the hitch and re-locking it before / after maneuvering. Everyone who sees it in action has that "jaw drop" reaction to it. Hooking up is very easy, and the engagement is VERY positive - you cannot miss getting it locked in place. Under tow, it is much more quiet than the previous one we used (loaner), and there is zero "lurching" or "chucking" as we experienced with the previous unit.

My only (minor) complaint is that I wish it wasn't quite so heavy, but it IS built like a tank. I probably could have gone with a lighter-duty unit for my specific 5th-wheel, but didn't want to have to replace the hitch if I ever upgraded to a heavier unit.

As for etrailer: everything I've purchased from them has shipped quickly, arrived (undamaged) on time, and has been of excellent quality. Thanks!



by:

Excellent product easy to install fit perfect and easy to hitch up well built exceeded my expectations.



by:

Easy installation.



by:

Quality is good. Installation was tricky without a lift. Some of the bed rail bolt holes (passenger side rear rail) where nearly impossible for a large hand to fit the nut on the bolt. Actually had to have my wife crawl under the truck and slide her hand in the brace to install the nut. Getting a decent size torque wrench into the space was also imposible. The front drivers side rail bracket required removing several vehicle lines and wires which was easy however the bracket covered the holes where the wires attached to the frame, so now they are hanging zip tied together. Hitch/ fifth wheel looks good quality but very heavy. Installed a 400 .lb capacity electric winch from harbor freight to lift the hitch. Firestone airbag helper springs was easy install but getting the exact straight cut on the hose end that hooks to the fill port was challenging to keep it from leaking
Videos were very helpful



by:

Works as advertised



by:

I would not buy this hitch again because --
1. It takes up to much space in the truck bed
2. It is over built thus weighs to much
3. It is very hard to hook up because the hitch swivels when unhooking, thus making the hooking up very difficult lining up on an angle.
4. With this hitch I cannot lock out the swivel feature. My old hitch I could lock it out

I would buy from E Trailer again there sales people are great and delivered time was great. The hitch choice was my mistake not E Trailer's



by:

received the hitch from the shipper. everything was well packaged onto one pallet and cellophane wrapped. Inspected all the components - no issues. this weekends project is to install the hitch.

  • Install Kit for Demco HiJacker 5th Wheel Trailer Hitch on a 2008 GMC Sierra 1500 with 5-1/2 Foot Bed
    There are a couple of Demco HiJacker autoslide 5th wheel trailer hitches. One fits above the bed rails and one fits below the bed rails. The benefit of the below the bed rails is that when the hitch is removed the bed is essentially clear for cargo. I can give you recommendations for both. For above the bed rails you can use either installation kit # DM8552009-71, which is a universal kit that will require drilling to install the frame brackets, or # DM8552013-71, which is a custom kit...

  • Fifth Wheel Hitch Recommendation for a 2011 Chevy Silverado with 5-1/2 ft Bed
    It is possible to install a fifth wheel hitch in the bed of a 5-1/2 ft bed 2011 Chevy Silverado 1500, but since the bed is so short it makes things a bit more interesting. The only slider hitch we offer that will slide far enough back to give you turning clearance is the Demco Hijacker Auto-Slide part # DM8550040. This hitch has 22-1/2 inches of sliding travel compared to most sliders that can only go about half that. For a rail kit to install this hitch you will need the custom install...

  • Best Sliding Hitch Recommendation for a 2014 Chevy Silverado 1500
    For a slider hitch for your 2014 Chevy Silverado 1500 6-1/2 foot bed I would recommend an auto slider like the Demco Hijacker part # DM8550034. Not only will this allow you to have tight turn clearance but since the hitch slides automatically you will never have to worry about getting out of the vehicle and manually sliding the hitch when in a parking lot. I attached a review video for you to check out as well. For the rail kit the best option is go with a custom install kit like the part...

    Since your truck bed is shorter than 6 feet long there's only one slider hitch that will have enough clearance to allow you to make tight turns and that's the Demco Hijacker Autoslide part # DM8550040 which slides back 22-1/2 inches which is about twice as much as other options.

  • Recommended Fifth Wheel Options For 2007 GMC Sierra Crew Cab With Short Bed
    With the length of the truck bed in your 2007 Sierra, a standard sliding fifth wheel hitch will not provide enough clearance for you to execute turns when towing. There are two ways you can go at this. I recommend going with the Demco Hijacker Autoslide, part # DM8550040. This hitch gives you 22-1/2 inches of additional clearance so you can make those tight turns. For above-bed rails you can use part # DM8552013-71.

    It is possible to tow a camper with a 5-1/2 foot bed if equipped properly, which I can help you do. First thing you will want to do is make sure you find a 5th wheel hitch that is rated properly for your camper. Next with a short bed you will definitely have clearance issues with the truck and camper when making turns so you will want to make sure that you get a hitch that allows for extended travel like the 22-1/2 inch travel that the 13K Hijacker Demco 5th Wheel AutoSlide # DM8550040...

    Hey there Joe, that's an interesting question. The advantage of the Autoslide that fits directly into the puck system of your 2020 Ram 2500 - the Demco Autoslide 5th Wheel Hitch w/ Slider - Ram Prep Package # DM69GV - is really just simplicity. You aren't tasked with using and keeping track of an extra piece in your truck bed like you would be with using an adapter.

    Hey Pat, The Rhino box definitely is shorter than what most Rver's were hoping for so we get this question all the time. Switching to a MORryde Cushioned pin box designed with a Rhino box bolt pattern unfortunately won't give you extra clearance since they made them with a matching 13.27" length from the king pin to the first set of bolt holes. It will help reduce chucking and road vibration though. If you went with this pin box you'd want part # MR83QR to match your GVWR to the shear...

  • Which Demco AutoSlide Works w/ the GM Factory Puck System in a 2024 Chevy Silverado 2500?
    There are two Demco Autoslide 5th wheel hitches that have the side plates that mount in the GM factory puck system. These work with the Silverado's and Sierra's made after the 2020 model year.

  • Lubrication And Maintenance For A Demco Autoslide 5th Wheel Trailer Hitch
    Demco has instructions listed for proper lubrication of the Demco Autoslide 5th Wheel Trailer Hitch w/ Slider # DM8550034, which I've attached below. You can use WD40 for the lock bar/handle and for the rest you'll want to use White Lithium Grease # L11354 to avoid attracting dirt and debris that could bind up the hitch.

  • Recommended 5th Wheel Rail Kit for a 2023 Chevy Silverado 2500
    Yes, you can definitely install a 5th wheel hitch without the factory puck system. It looks like back in 2020 you bought the Demco Autoslide 5th Wheel Trailer Hitch item # DM8550034 from us. To install it in a 2023 Chevy Silverado 2500 that doesn't have a puck system you will need the Reese Quick-Install Custom Outboard Installation Kit w/ Base Rails item # RP84FR. This is a custom fit kit that installs in existing holes in your trucks frame. If you're using a different 5th wheel hitch...

  • What is Needed For Demco Autoslide 5th Wheel HItch on 2022 Ford F-250 & Air Ride Pin Box
    Hey Bob, thanks for writing in, and let's start with the hitch for your 2022 Ford F-250. You made a superb choice going with the Demco, as the Autoslide is as good as it gets for a sliding hitch.

  • Are There Different Mounting Brackets Available To Transfer A Demco Autoslide To A GM Puck System
    You can definitely swap out the hitch for a new one if you're wanting to go with a fixed base that would weigh less than your Demco Autoslide # DM8550034, but you could also just swap out the mounting plates to save money. If you want to just swap out the plates you'll need part # DM49GV. If you want to switch to a new hitch with a fixed base then I recommend the B&W Companion OEM 5th Wheel Hitch for Chevy/GMC Towing Prep Package # BWRVK3710. This hitch has feet to drop right into the...

  • Is A Capture Plate Needed To Tow A Trailer With A Gen-Y Pin Box With A Demco Autoslide
    Yes, you'll need capture plate # GY98FR in order to tow a trailer with a Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box # 325-GH-8040 using a Demco Autoslide 5th Wheel Hitch # DM8550034. As the head of the Autoslide turns it slides back giving you more turning clearance. Without a capture plate the king pin would be able to rotate in the jaws of the hitch and wouldn't force the head to turn and slide back.

  • Comparing 5th Wheel Trailer Hitch Jaw Designs for a Hitch on a 2012 Ford F-250 Short Bed
    There are a few different jaw types on a 5th wheel hitch. A slide bar can be found on the less expensive hitches like a Pro Series PS30094. A slide bar, while secure, is going to provide the least snug fit and you will notice the king pin making some noise. Next are double jaws and are much more secure and cut down quite a bit on the movement and noise of the king pin. Many Reese, Curt, and other brand mid-level and higher end hitches have the double locking jaw design like # RP30075. The...

  • Will the Demco Hijacker Autoslide 5th Wheel Trailer Hitch fit 2022 Ram 3500 With OEM Prep Package
    It sounds like you want to know if the Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider like the # DM8550034 will fit your 2022 Ram 3500 with 6-1/2 Foot Bed and OEM Prep Package. This will work for your Ram 3500, but you will also need the Demco 5th Wheel Rail Adapter for Ram OEM 5th Wheel Towing Prep Package # DM6099.

  • Can Demco Autoslide 5th Wheel Hitch Fit 2011 F-250 With B&W Turnoverball Gooseneck Hitch
    I have two options for you, but you won't be able to use your Demco Autoslide with the B&W Underbed Installation Kit. You can't mount additional rails with the B&W hitch installed, and you can't use an adapter since it is unable to withstand the torque from the autoslide. The first option is to sell the Demco and get a B&W Companion # BWRVK3400-5W. The other option is to remove the B&W underbed hitch and install new rails to work with your Demco. You can choose above or below bed rails...

  • Can Components From A Demco Recon Be Used With A Demco Autoslide 5th Wheel Hitch
    The Universal Above-Bed Base Rails # DM6071 you referenced would be compatible with your 2023 Ford F-250 as long as you had the Demco Premier Series Custom Mounting Brackets for 5th Wheel Above-Bed Base Rails # DM42GV. As for the Recon hitch components, you will not be able to use either of these with the Autoslide hitches and would have to purchase a new Demco Autoslide 5th Wheel Trailer Hitch w/ Slider # DM8550034. Both the bases and heads are different designs and wouldn't be compatible...

    If your 2018 Chevy Silverado 2500 has the 6-1/2 foot bed and isn't equipped with the factory pucks/rail kit, then I recommend the Demco Above-Bed Base Rails and Custom Installation Kit # DM8552011-71. This kit will include everything needed to attach the excellent Demco Hijacker # DM8550034 that you referenced to your Silverado. The custom brackets in the kit will use existing holes in the truck's frame to eliminate the need to drill into the frame during installation. I have attached...

  • Is Demco Hijacker Autoslide Compatible with Reese Airborne 5th Pin Box on Grand Design
    Thanks for reaching out, Chuck! The 18K Demco Autoslide 5th Wheel Trailer Hitch w/ Slider # DM8550034 will work great with your Reese 5th Airborne pin box - you just need to lockout the rotating turret (if it has that feature) and then use either the Locking Plate # DM6026 if it's an older pin box, or the Locking Plate # DM77GV if the pin box is from 2020 or after. If you don't already have bed rails installed on your truck then I also recommend picking up the Curt # C16411-204 which...

    The Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider # DM8550034 is designed specifically for short bed trucks like your 2019 Ram Classic Short Bed. To know if it will be compatible with your current rails you'll just need to measure the distance from the center of the front rail to the center of the rear rail to determine if they are Industry Standard Rails (ISR). If you find the measurement between the center of the rails to be 22" (as shown below) then you do have ISR rails...
