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" + 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.

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

- DM8550034

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

Haven’t had a chance to use it yet however it arrived quickly and in great condition. Appears to be very well built. 721164

The hitch works as expected. It is very heavy duty and has held up well. I have pulled a 13,000 pound trailer in excess of 10,000 miles with no problems. I purchased this one because it does not require any adapters for the pin box/capture plate. This means I can pull any standard 5th wheel. The other brands that I found all required a special plate and was specific to the trailer (Not one size fits all). The only downside is that the hitch is very heavy. But that is to be expected for a very heavy duty hitch. 610491

The hitch is indeed heavy. If you have a chain hoist available, using a lifting bracket like part # DM6100
Demco 5th Wheel Lifting Bracket
see link would certainly make installing and removing the hitch much easier.

I've been using the Hijacker 1800 auto slide hitch for my 38' 5er for a year now and I'm very satisfied with it's performance. For the first couple of months of use I had a terrible time getting the jaws to lock when reconnecting to my trailer. Once, I tried for an hour and finally called Demco. somehow we got it to lock but I was really not sure what made it work. It continued to give me problems after that. I finally figured out that after backing onto the trailer pin box I would set the parking brake and try to pin the handle without success because I was leaving some back pressure on the jaws against the king pin. I started making sure there was no back or forward pressure on the jaws before setting the parking break...no problem since as long as I am careful about this issue. On level ground I put the truck in neutral and let it move slightly forward or back, whichever way it wants to go. Works nearly every time. My only problem now is accelerating away from a stop it feels like the trailer slips back in the hitch with a big jerk. I've adjusted the bolt in the front of the hitch frame as the instructions indicate (back off 1/2 turn after the bolt touches) but no dice. I've tried several adjustments and it does't change a thing. Studying the hitch I can't see where the slack is. Otherwise, for turns and overall functioning it works perfectly...Thanks DEMCO. 481306

Installed in my 2014 Silverado. This looks to be a very heavy-duty hitch that doesn't require a capture plate. 565372

This hitch has worked well for me. It is now used in a 2018 GMC Sierra 2500. It is just tall enough that I can see it in my rearview mirror to make it easy to get lined up with the kingpin

Glad to hear that you're getting good use out of your Demco Hijacker 5th Wheel Hitch! If you get to the point where you'd like a different angle we have different cameras you can use in place of your 3rd brake light. I have linked our selection for your 2018 GMC Sierra 2500 for you to filter through.

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 548218

This demco hitch part DM8550034 is a completely gear driven hitch. Whichever angle you uncouple at is the same position the head will stay in until it is coupled back up. It is a good idea to couple up at as straight of an angle as possible. If there is ever a situation where you have to uncouple at an angle you can physically turn the head back to a straight position by taking the head off the hitch and putting a straight bar through the assembly for some leverage. The head should not be swiveling during coupling unless the main bolt is loose. The bolt that holds the gear assembly together has to be torqued to the specific foot lbs in the installation instructions or the head may swivel and cause issues during coupling. That bolt is part 05366 in the instructions.

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. 593790

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. 377393

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. 604256

Just got back from a 20 day road trip with our 5th wheel camper using the Autoslide hitch. It worked flawlessly! I have a short bed Dodge Ram and had to get into some areas that included tight turns. Although I was initially weary of how close the trailer was to the cab of my truck, it was always at a safe distance (and no manual unlock to slide!) Great product, would definitely recommend! 906204
