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.
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.
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
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 . 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" + 14" = 50". If your fifth-wheel trailer is 84" wide, take half (42"), then plug in: 50" - 42" = 8" of clearance.
Note: At least 4 inches of clearance is recommended to safely execute a 90-degree turn.

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.923539
I wish the place I bought my camper would have recommended this from the start. Makes owning a 5th wheel so much easier!1243393
by: DeLoyd McDaniel09/02/2019
The kit came with everything and instruction. Very easy to understand how it all fits together. Getting the rail bolt washers and nuts were pretty difficult to get started. You just got to take your time and you will get. 697098
We received the hitch in great shape. The boxes were in very good shape. The only problem was a missing polyurethane dampener that was’t included. I called and received great service from etrailer. I have had a demco autoslide for several years but it was an 18000 pound hitch and went to a 21000 pound hitch. They are the best hitch for a shortened truck on the market1496745
by: Scott11/28/2018
This is a quality piece of equipment. I can't wait to use it. The installation directions were complete and easy to follow. Looks fantastic.585957
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

Best 5th wheel hitch ever for a RAM 3500 mega cab. No issues with the RV coming close to the back of the cab or back glass. I would recommend this hitch to anyone searching for a 5th wheel hitch for a Ram mega cab, I wish I knew about it when I first purchased my Ram mega cab, I learned the hard way, after busting out my back glass...and trying several hitches. This hitch is truly an autoslide. I have showed several short bed guys this hitch and told them the cost of the 5th wheel hitch is worth it.... It is top of the line. This will be the last 5th wheel hitch I will ever need to purchase.1335898

thanks to Greg S. he helped me a lot in choosing and answering all my questions852532
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
by: Richard06/05/2018
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

Pretty pathetic service from etrailer. Order place on Aug 25th with ETA of the following Friday (1o days). But nope, I wait. It finally (and supposedly ships) on Sept 7th (13 days later). On Sept 14th I received a confirmation that my items were delivered, but nope. Not to my house anyway. Avoid these folks if you want something to arrive when they say it will arrive.1152620
by: Randall09/04/2021
This is an initial impression review. The hitch was delivered on a pallet and arrived earlier than expected. Everything was well packaged with all associated hardware. This hitch was mounted on Reese Quick-Install Custom Outboard Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches ( in the bed of a 2007 Dodge Mega Cab 3500. Overall it appears to be well constructed, unfortunately, I did have issues with bolting the hitch adapters to the hitch. The hardware is either grade 3 or 5 (looks like 5) and did not torque well. I had one bolt that stretched and sheared before I reached the torque spec (photo attached). I'm not sure if this was designed to use the weaker hardware or a business decision, however, all eight bolts were replaced with grade 8. I do look forward to utilizing this hitch in a few months. I would at photos, however it appears that I can't.1143856
by: Kenneth 05/12/2021
It works really well. It is really nice not to worry about the 5th wheel trailer clearance when making tight turns. We pulled the rig several hundred miles last summer and at least 3000 more since January with no issues. Also I used the height adjustment feature when setting up my trailer.
When I received the shipment I was impressed by how well it was packed. It would have been nice to had had help, but I was able to assemble and mount it myself. The instructions were good, and as I said, we have had no issues during our first snowbird season.1035688
by: Lucas03/13/2017
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
by: William07/25/2021
Works great except life would be so much simpler if they had a hole drilled on each side to remove the lock pins that are below it in the mounting plate to be able to remove the unit from the truck.1104839
by: Ryan05/15/2022
Really like this hitch. Two things I don't like however, are 1) you need to backup almost perfectly the way you unhooked or it's a bear to hitch backup. 2) I don't like the bolts for the pinbox. Wish there was a quicker alternative. Hate getting a wrench out to tighten and losen.1298455
by: Robert 01/31/2023
Very easy install. I had rails in the truck I purchased which were universal fit with the welded angle iron but were not able too take the load I was going to put on them. Glad I changed them because the welds were very weak and could have caused me a serious accident.1510551
by: Gregory 08/21/2021
Purchased a heavier 5th wheel so this one replaced my pull rite. No more capture plate to deal with. Very happy with this hitch.1129491
by: Virgil03/28/2022
The hitch and adaptor arrived in three days. Everything went together fairly easy considering I had just torn my rotator cuff a week earlier and my helper never showed up. Definitely would have been easier with two people. Had planned a trip next week to Yellowstone National Park but will have to wait until after surgery. Will do a follow up review after I am able to see how well auto slide works. Great customer service!1278732

There is absolutely an automatically sliding fifth wheel hitch that will work on your 2019 Ford F-350 Super Duty and allow you to tow your Keystone Raptor toy hauler.

The correct set up will depend on if your 2019 F-350 has the Ford Fifth Wheel Prep Package (the puck system) or not:

Since your truck has a short bed you are going to need a slider hitch to allow you to make sharp turns without cab interference. Most slider hitches do require you to get out and activate them when you get to sharp turns so my favorite slider hitch to recommend is the Demco Hijacker Autoslide part # DM8550035 which will automatically slide as you make tight turns to give you the needed clearance.
You will need the Ram rail kit adapter part # DM6099 as well so that the hitch can fit the view full answer...

For towing a 20k fifth wheel hitch with your 2015 Chevy Silverado 3500 short bed you are going to need a slider hitch to allow you to make tight turns without cab interference. Because of that I would recommend the Demco Hijacker AutoSlide part # DM8550035 which will automatically slide as you make tight turns which prevents you from having to get out and manually activate the slider everytime you get to a parking lot.

Hi Kevin,
The handle assembly for your Demco # DM8550035 can be purchased with part # DM15934. As for the capture plates the # DM14743-95 would be the standard replacement. There are other options but they are pin box specific so I'd need to know what you have to ensure you're ordering the correct capture plates. You can send me those pictures as well. view full answer...
The Demco # DM8550035 Hijacker Auto Slide 5th wheel hitch weighs right at 310 lbs, while the
# DM85500334 weighs 285 lbs. Demco also offers a lifting bracket, part # DM6100, which would make getting the hitch in and out of the truck much easier if you have access to a hoist. view full answer...
Yes, the Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider part # DM8550035 is the best 5th wheel hitch we have for your 2015 Ram 2500 as long as you do not have the RamBox.

I really like the Demco Hijacker Autoslide, part # DM8550035. The hitch has a high quality jaw that holds the king pin very tightly, avoiding much of the chucking and rattling. The # DM8550035 has a 21K capacity, and will slide rearward automatically during sharp turns to provide 14 inches of clearance between the front of the fifth wheel and the rear of the truck cab. No more exiting the truck to release the slider. The # DM8552026-71 install brackets/frame rails are recommended.

For your 2016 Ram with the factory puck system I highly recommend the Demco Hijacker Autoslide # DM8550035 along with the Rail Adapter # DM6099.
The Demco Hijacker is an excellent hitch not only because of its automatic slider that allows you to stay in the comfort of your cab during sharp turns but also because of its wraparound single-piece jaw coupled with the 3/4 inch thick steel locking bar that provides an extremely secure connection to the trailer. This tight and sturdy attachment view full answer...
The correct Demco Hijacker Autoslide 5th Wheel Trailer Hitch for a 2014 Ram 3500 is part # DM8550035. Please note, you will still need the Demco Hijacker Premier Series Above-Bed Base Rails and Custom Installation Kit part # DM8552026-71 or the Demco 5th Wheel Rail Adapter part # DM6099 if you have the factory pucks.
Please note, the highest weight capacity for the Demco Hijacker is 21,000 lbs but so long as the GVWR of the trailer does not exceed this (it doesn't) you'll be good view full answer...
The Pullrite SuperGlide 2315 is a great 5th wheel hitch in general however, it won't be best for your 2018 Ram 3500. The reason for this is because the height of it cannot be adjusted and the new Ram has pretty tall besides so you are going to need a 5th wheel hitch that can be adjusted vertically to account for this. For that, the best option we have for you that will allow you to retain the auto-slide function is the Demco Hijacker Autoslide 5th Wheel Trailer Hitch part # DM8550035 with view full answer...
When determining the height of your 5th wheel hitch you'll need to measure the height from the ground to the floor of the bed (where the base of the hitch will be sitting) and the height of the ground to your king pin when the camper is level. The difference between these two numbers is what you want your hitch's height to be.
For example: if your truck bed height is 42" tall and your king pin height is 58" then you would have a difference of 16". The Demco Hijacker Autoslide 5th Wheel view full answer...
The Demco Hijacker Autoslide 5th Wheel Trailer Hitchs like part # DM8550035 are compatible with the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Boxes like part # 325-GH-8040 which fits a Lippert 1621 pattern. That said, you will need an adapter for this, the Gen-Y Capture Plate part # GY98FR but that will be all. This is a great combo which provides both cab clearance and a cushioned ride.

Easily the better option between the Demco Hijacker and Pullrite SuperGlide for your 2019 Ram 3500 is the Hijacker, which is what I would go with and highly recommend you do as well.
The reasons are pretty straightforward, and starts with the elite jaw system of the Hijacker. It is a single-piece jaw that wraps totally around the king pin, and the connection is enhanced by a 3/4" solid steel bar that locks into place once the jaw is closed. This reinforced jaw system is what will give view full answer...
You have a couple options for moving your Demco Autoslide 5th Wheel Trailer Hitch # DM8550035 to your 2023 GMC Sierra 2500 with the factory in bed prep/puck system. First the best way in my opinion is to remove the mounting brackets on the side of your hitch and add the Side Plates # DM49GV. These will allow you to set the hitch into the factory mounts on your Sierra.
The other option is using a Demco 5th Wheel Rail Adapter # DM6333 to act as an adapter between your bed mounts and your view full answer...
For The 2022 Ram 2500 Short Bed With Factory Pucks I recommend The Demco Autoslide 5th Wheel Trailer Hitch w/ Slider # DM8550035.I like this slider hitch over the others because when making sharp turns you will not have to get out of your truck and adjust the hitch. It will slide by itself and then when you get the vehicle and trailer straight again it will go to normal. It is also extremely easy to install.

The 5th wheel hitch I recommend for your 2016 GMC Sierra 2500 HD Denali is the Demco Hijacker Autoslide, , 21K # DM8550035. For the 18K hitch you would want part # DM8550034. The rail kit for your truck that is compatible with the Hijacker Autoslide is # DM8552011-71.

The Demco Hijacker Autoslide 5th wheel hitch is compatible with a Rota Flex pin box, you will just need to add capture plates:
- Demco Hijacker Autoslide Capture Plates for Trailair Rota-Flex Pin Boxes # DM6171

Yes, you can definitely use either a 16,000 lb or 21,000 lb capacity 5th wheel hitch in your 2019 GMC Sierra 2500 that has the Demco 6071 base rails that come in the Demco Hijacker Premier Series Above-Bed Base Rails and Custom Installation Kit # DM8552011-71.

Demco does not provide measurements for rail placement for installation kit # DM8552011-71 for your 2015 Chevy Silverado 2500 but what they do say is that the hitch can be centered over the center of the rear axle up to 3 inches forward.
On a short bed truck you will want it as far back as you can so centered over the axle is a good place for the hitch. Now, from the center of the hitch forward on the truck to the front of the rail will be approximately 14 inches. So you would measure view full answer...
The 2016 Chevy Silverado 2500 came with two bed length options. 8 foot and 6-1/2 foot. If yours seems to be a 6 foot bed that would mean it would fall in the 6-1/2 foot bed range which is what the part # DM8552011-71 is designed to fit.
I attached an install video as well.
For a sliding fifth wheel hitch to fit these rails to allow you turning clearance the Demco Hijacker part # DM8550035 would be your best option. It automatically slides as you make tight turns to give you the needed view full answer...
The Demco Hijacker Autoslide 5th wheel hitches that fit the underbed rails and above-bed rails are exactly the same but for the side plates they come with. The side plates are what attach the Hijacker to its respective rails, and apart from that there is absolutely no difference whatsoever between the two hitches. So, depending on what style you want, you can choose from one of the following options:
- Underbed: Demco Hijacker Autoslide 5th Wheel Trailer Hitch with Slider # DM8550022

Check the legs/base of your hitch. If it indicates Ultra or UL then you can use installation kit # DM8552011-71 on your 2011 Chevy Silverado 2500 short bed. If it shows SL then you would instead use # DM8553007-12.
If there is no indication send some pictures of the legs/base so I can see how it attaches to the rails. view full answer...

Thanks for the picture! Those holes are not from an OEM puck system because the cab to tailgate dimensions are too short. It looks like the previous owner used the Underbed Rail and Installation Kit for Demco UMS 5th Wheel Hitches item # DM8551010. This system worked similar to an OEM puck system but only with Demco hitches. I have linked a dimensional drawing below for you to compare to what is currently on your truck. I have also attached an installation video.

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.
