Automatic Slider Makes Cornering Easy

Most often used on trucks with 6-1/2' beds, a slider helps to eliminate clearance problems during slow-speed turns. When you are towing a fifth-wheel trailer, your hitch must be situated on the cab side of your truck's rear axle. However, at slow speeds you can use a slider to slide the fifth-wheel hitch (and the trailer) toward your truck's tailgate and past the rear axle, creating enough space between the cab of your truck and the trailer to permit less-restricted turning.


Normally, you'd have to get out of your truck and pull a lever to release the slider before every turn, but what if there was an automatic system? Imagine having 14" of extra clearance while towing your fifth-wheel trailer. Now imagine having this without needing get out of the truck to move your slider. The Demco Hijacker Autoslide makes this fantasy a reality. The Autoslide automatically glides back smoothly when you make a sharp turn so you can maneuver effortlessly around tight corners within campsites and parking lots.


Demco Hijacker Autoslide

The base of the Autoslide has a built-in rack-and-pinion gear system that operates automatically. As your truck turns, the pinion in the base also turns. This activates the rack gear, which causes the rotational force of the truck to be converted into the linear sliding action of the hitch. So, when your truck makes a sharp, slow-speed turn, the gears inside the Autoslide force the hitch head to slide down toward your truck's tailgate in a smooth, controlled motion. This way, any time that your truck turns more than 10 to 15 degrees, the Autoslide will ensure that there is enough clearance for your trailer to complete the turn as well, and it will do so without any jerking or binding.


In order for the rack-and-pinion assembly to function as designed, the pin box must be stabilized on the hitch head. Normally in a fifth-wheel hitch, the king pin moves inside of the hitch head so that the trailer can turn. With the Autoslide, the king pin remains fixed inside of the jaws of the hitch and it is the hitch head itself that turns. This is thanks to the capture brackets on the sides of the head that brace the pin box from both sides to hold it in place on top of the hitch head. This is done to ensure that there is enough resistance within the hitch when your truck turns to properly activate the rack-and-pinion gear mechanism.


Demco Hijacker Autoslide capture bracket

To stabilize your pin box on the hitch head, simply push the capture brackets up against your pin box once the trailer is coupled and tighten the outer bolts and the inner jam nuts. The Autoslide head and brackets will fit standard pin boxes that are between 12" and 14" wide. If you have a Glide Ride, Mor Ryde, Trailair Tri Glide, or 5th Airborne pin box, you must install a special locking plate (sold separately) as well.


When you straighten your rig out again and your trailer moves back in line, the hitch head will rotate back to center and slide back toward the cab into the straight towing position.


Secure Wraparound Jaw with Locking Bar

Demco Hijacker Autoslide wraparound jaw and locking bar

The single-piece, strong wraparound jaw completely surrounds your trailer's king pin for 360 degrees of contact. This wraparound jaw provides a more secure connection than standard 2-piece jaws that close in on the king pin from the sides. The increased jaw-to-king-pin contact on the Autoslide offers tighter tolerances around the king pin, which minimizes both rattle and chucking, for a smooth, quiet ride.


A 3/4" solid steel locking bar spans the area in front of the jaw. This bar provides an added barrier of protection against accidental disconnection so you can have peace of mind that your trailer is secure. The locking bar is attached to the jaw and to the spring-loaded handle. The bar automatically locks when the jaw closes around your king pin.


Double-Pivot, Cushioned Hitch Head

The double pivoting, cushioned head improves your towing experience dramatically by helping to reduce jarring and unwanted noise. Built-in pins allow the hitch head to pivot back and forth and side to side. And hooking up is easy because the hitch head will automatically pivot to the proper angle when it comes into contact with your pin box.


Three polyurethane dampeners help to cushion the movement from the pivoting head and to reduce towing noise. Two of these dampeners are built into the head assembly to cushion the head's side-to-side pivoting. The third dampener cushions the back-and-forth motion and must be installed in the hitch prior to use. Installation of this third dampener is easy - simply press the dampener up into the pre-drilled hole underneath the hitch head.


Easy Installation

The Hijacker Autoslide hitch is designed to attach to universal above-bed base rails (sold separately) . The hitch will fit most industry-standard rails, including those from B&W, Curt, Demco, Draw-Tite, Hidden Hitch, Husky, Reese, and Valley. The hitch comes pre-assembled for an easy installation. All you have to do is bolt on the side plates and attach the head to the hitch base.


The side plates have 2 functions. They contain the feet that fit into your above-bed rails, and they allow you to raise or lower the hitch head to better match your pin box height. After you choose your desired height setting, simply bolt the side plates to the hitch base with the included hardware. Then attach the base to the rails with the included safety pins.


Clearance Formula for Short Bed Trucks

Use the formula below to ensure there will be enough space between your truck cab and trailer when executing a 90-degree turn.


(A+B) - C = Clearance


A = Distance from the center of fifth-wheel hitch jaw to truck cab

B = Length of Travel (14")

C = Width of trailer divided by 2 (to get half)


For example: If the distance from the center of the hitch to the cab is 36", 36" + 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.

Bought for use on my 2019 Ram 2500 shortbox because I was having clearance issues while turning. I could barely make a 45 degree turn. Installed the unit in about an hour from delivery to finish. Have an extra guy or two to help cause its heavy. I can know back 90 degrees if I had to with about 4-6 inches of cab clearance 853636

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

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

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


Comments
After about 6000 miles the hitch developed some fore and aft movement. After another 2000 miles it seemed to be excessive with a loud clunk when stopping and starting. Yes, I do grease it as per instructions before each trip. I called Demco and told them the problem and they sent me the parts I needed at no charge since it was under warranty. Since I had the mechanical ability I disassembled, diagnosed and repaired it myself. I thought later on that I should have been compensated something for my time only because if I took it to a dealer they would have charged for labor. Just a suggestion, there needs to be an easier way to lubricate this hitch rather than removing the large pivot pin and also the large pivot bolt and greasing them by hand. Some well placed grease fittings would make this job a lot easier and cleaner, especially when on the road. Also, the hitch owner would be far more inclined to do it. Other than that the hitch has performed great and I am very happy with it. Thanks.

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

Review from a similar Hijacker Autoslide in Fifth Wheel Hitch


Hitch is good. I did have a problem aligning hitch in a hilly sandy soil, truck would shift in the sand causing a misalignment with the hitch, this caused it to bind and would not line up. Had to loosen guides for it to lock in, then re-adjust after pulling it straight out. 845680

Review from a similar Hijacker Autoslide in Fifth Wheel Hitch


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 830340

    It is possible!

  • Comparing the Pullrite SuperGlide and Demco Hijacker for a Ram 3500
    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...

Although they do share some similarities (like the autosliding function, single-jaw to secure the king pin, and cushioned heads) the Demco stands out because it has 3 different height settings, 15-1/4", 16-1/2", and 18", features a 3/4" steel locking bar to reinforce the king pin connection, and doesn't require a locking plate unless you are using a special pin box.

    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.

  • Best 5th Wheel Hitch Recommendation for 2015 Chevy Silverado 3500 Short Bed with Rails Installed
    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. This hitch also fits the industry standard fifth wheel rails you...

  • Auto Slide Fifth Wheel Hitch Recommendation for 2018 Ram 3500 with Air Suspension
    I have a great solution for you. The Demco Hijacker AutoSlide Hitch part # DM8550035 is designed to fit industry standard style fifth wheel rails. So while the Demco brand rails for your truck don't fit with the air suspension vehicles, the Curt rail kit part # C16426-204 does fit the air suspension versions of your 2018 Ram 3500 so it would work well. The hitch I mentioned has a 21k capacity and will automatically slide as you make tight turns.

  • What Is Angle To Hook Up Trailer With The Demco Hijacker Autoslide 5th Wheel Trailer Hitch
    I reviewed the instructions for the Demco Auto-Slide 5th Wheel Hitch, Item # DM8550035, and the coupling and uncoupling needs to be straight or slightly angled with alignment. It works pretty easily with 10-15 degree angle but anything larger will not allow proper coupling. If you have a factory rail kit, you will need installation rails Item # DM6099. If you do not have the factory rail kit, you will need Item # DM8552026-71. I have attached the installation instructions, an...

  • Comparing Demco and Pullrite Automatic Slider Hitch for 2017 Ram 2500
    The Demco Hijacker Hitch part # DM8550035 that you referenced has been confirmed as a fit for your 2017 Ram 2500 with hitch package and short bed as long as you use the adapter part # DM6099 and would be what I would recommend for you. It would not require any rail kit adapters either. It is very similar to the Pullrite Superglide in operation. I have read many online reviews on other sites and forums where people compare the two saying that the Demco costs less and tends to be more...

  • Will Demco AutoSlide 5th Wheel Hitch Fit with B&W Turnoverball Gooseneck Hitch?
    The Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider - Single Jaw - Above Bed - 21,000 lbs # DM8550035 is not compatible with the B&W turnoverball gooseneck hitch # BWGNRK1314. The handle for the gooseneck ball will not work with the 5th wheel rails in place according to my contact at B&W. Unfortunately you will need to choose between them.

  • Fifth Wheel Hitch Recommendation for 2018 Ram 3500 Short bed With Rail Kit
    The 2018 Ram 3500 duallys have pretty high towing capacities. But from the research I did on your truck in order for you to have a higher capacity than 21k like you'd need you'll need to have a the Cummins diesel engine and at least the 3.73 gear ratio.

  • Compatibility of Demco DM8550035 Hijacker Autoslide With Pro Series Hitch Mounting Rails
    I'm not sure what you mean by 'side mounting rails'. The Demco # DM8550035 Hijacker Autoslide is compatible with industry standard bed mounting rails like those from Reese, Curt, Husky, Valley, Pro Series and B & W, so the hitch will be compatible with your existing Pro Series bed rails.

  • Will Demco Hijacker Fifth Wheel Hitch Fit Same Rails as a Curt Q20 Fifth Wheel Hitch
    Yes, the Curt Q20 fifth wheel hitch you have would install in the same rail design as the Demco Hijacker part # DM8550035 that you referenced.

  • Can Demco Hijacker 5th Wheel Hitch Hook Up to a Trailer at a 45 Degree Angle
    The issue with the angle restrictions on Demco 5th wheel hitch # DM8550035 is the auto-sliding feature. In order for it to engage/disengage properly when hooking up/unhooking it can only be at the 0 to 15 degree angle. A manual slider such as the Curt A20 # C16541 would be a better option.
