Note: This fifth-wheel trailer hitch is not compatible with Sidewinder or Revolution king pins. Do not use any device that changes the pivot point of your trailer's king pin with this hitch.


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 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.

Video Transcript for Demco Fifth Wheel Installation Kit DM8552000 Review

Today we're going to take a look at the Demco Hijacker Premier Series Custom Mounting Brackets for Fifth Wheel Above-Bed Base Rails. This is a custom-fit part. It is designed to fit the 2011 and newer Ford F-250, F-350, and F-450 Super Duty trucks with either the 6 3/4 foot truck bed, or the 8-foot bed without the factory rail kit. Now on any custom-fit part I always like to recommend for you to go to our website, use our fit guide, put in your year and model vehicle, and it'll show you if this part will work for your application. Now these installation brackets will mount beneath your truck bed to provide attachment points for your Fifth Wheel rails to attach to. Now the base rails we do sell separately on our website.

It's part number DM6071. The rails is what sits in your truck bed and allows the installation of the Fifth Wheel hitch to the truck. Now these are custom-fit brackets. They mount to the outside of the frame using existing holes in your vehicle's frame. Because of that they minimize drilling, reduces installation time, and they're designed to avoid known obstacles that are along your specific vehicle's frame. Notice they have a tag on each side.

Driver's it says here, passenger here, so it helps you know what position these go in. Now these parts are a sturdy steel construction, have a nice black powder coat finish to help resist corrosion. All the hardware to install them is included. It comes with a nice set of detailed instructions that'll describe how to install it. It even has pictures to show you how to install it.

These parts are made in the USA, but that should do it for the review on the Demco Hijacker Premier Series Custom Mounting Brackets for Fifth Wheel Above-Bed Base Rails.

  • 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.

So the dimension between the front of the hitch and the front wall of the truck bed can vary by a few inches between bracket kits available from Demco, Reese, Curt, Husky, B&W, etc. If the Demco # DM8552000-71 bracket kit is used, the front of the hitch would be right about even with the front edge of the bed...

The ride quality will be a bit stiffer unloaded but that's not why you need the truck. I'd also recommend a long bed truck so that you have turning clearance without needing a slider hitch.

    Hey Joe, Does your Bradford flatbed have a recessed gooseneck hitch already installed or is it just the flat bed right now? If not, you're going to need to cut out space for a gooseneck hitch like the B&W # BWGNRK1500 to be installed. From there you would need a 5th wheel hitch that mounts to a gooseneck ball like B&W's flat bed hitch # BWRVK3050. The bed height for a flatbed is typically a lot higher than a standard bed so a shorter hitch is typically going to be required so that the...

  • Best Sliding 5th Wheel Hitch For Clean Bed on 2020 Chevy Silverado 2500 With or Without Puck System
    These are really good questions and we can definitely set you up with the right 5th wheel hitch for your 2020 Chevy Silverado 2500 short (also called standard) bed, but to quickly answer your question about underbed brackets, there aren't any that are universal (as nice as that would be), they are only designed to be used with specific 5th wheel hitches.

  • Autoslide 5th Wheel Hitch Recommendation for 2019 GMC Sierra 2500 with Factory Pucks
    We have exactly what you need! For your 2019 GMC Sierra 2500 I recommend either the 18K Demco Hijacker Autoslide 5th Wheel Trailer Hitch # DM8550034 or the 21K Hijacker # DM8550035.

  • Could Hoist Remove Demco Hijacker 5th Wheel Trailer Hitch Slider # DM8550035 From Truck Bed
    The head of the Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider # DM8550035 that you referenced is rated to be able to handle up to 5,250 lbs of vertical weight. If you wanted to wrap a rope around the head to lift the weight of the hitch (300 lbs) the hitch would be totally fine.

  • 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.

  • Is a Wedge Available for a Trailair Pin Box to Use with the Demco Hijacker Autoslide 5th Wheel Hitch
    Although there are some wedges that Demco offers to use in conjunction with the Demco Hijacker Autoslide, like part # DM8550035, the wedges are made for specific specialty pin boxes and won't work with a standard pin box. For a standard pin box you need to use the capture brackets that already come with your 5th wheel hitch. If you want to upgrade your pin box to one that uses an air bag or shock to help enhance your towing experience just let me know what your pin box number is (like...

  • Best Sliding Fifth Wheel Hitch Recommendation for 2017 Ram 3500 Short Bed with Factory Rail Kit
    For a slider hitch for your 2017 Ram 3500 with the factory fifth wheel rail kit the best option I can recommend is a Demco Hijacker Autoslide hitch like the part # DM8550035 which has a 21k capacity. I really like this hitch as it automatically slides back as you make tight turns so you never have to get out and mess with the slider mechanism.

  • More Clearance for Short Bed With Atwood AB72 Pin Box
    I can help you figure out how to get more turning clearance with your short bed truck. Due to the style of the Atwood pin box you have on your trailer the Sidewinder is not recommended to be used. An alternative to this would be a sliding hitch. A sliding hitch will give you turning clearance for your trailer just not the 90 degrees that the Sidewinder provides. I really like the Demco Hijacker AutoSlide's, # DM8550035, technology because you never have to get in or out of your bed...

  • How to Tell if 2018 Ford F-250 Has Puck System to use Demco Hijacker Autoslide
    While the best and most certain way to tell if your 2018 Ford F-250 has the puck system is to call your local Ford dealer with your VIN, it should be pretty easy to tell otherwise. If your bed looks like the accompanying photo - with four accessible holes (pucks) and a gooseneck in the middle - you have the puck system. You can also tell based on how your B&W Companion mounts. If you insert it into the pucks you have the B&W Companion OEM 5th Wheel Trailer Hitch with Slider for Ford Towing...

  • Will Andersen Ultimate Allow a 90 Degree Turn When Towing with a 2017 Ram 2500 6-1/2 Bed
    The Andersen Ultimate Connection # AM3200 has a 9" offset. I am not sure if it will allow you to make 90 degree turns with your 2017 Ram 2500 6-1/2' bed but this can simply be determined by measuring from the back of your cab to the middle of the space in-between your base rails (or the pucks). Once you know that simply add 9" for the offset and the subtract half of the width of your trailer. The formula looks likes this: (A + B) - C = Clearance A = Distance from center of fifth wheel...

  • Can Trailair Flex Air # LC328492 Replace Lippert 1621HD Pin Box on a 2017 Jayco Seismic Wave 355W
    You are on the right track of choosing an upgrade for the Lippert pin box on your 2017 Jayco Seismic Wave 355W. Since the pin box is a 1621HD instead of a regular 1621 you need to go with a different pin box as the Curt Flex Air # LC328492 is only compatible as a 1621 replacement. If you like the Curt line then you can use the Curt Air Ride # LC158778. This is rated for 21,000 lbs and the only difference between this and the Flex Air is that the Flex Air has a pivoting head which further...

  • Could Above Bed Demco Hijacker Hitch Fit Same Rails and B and W Companion Hitch
    The B and W Companion hitch was designed to fit the underbed B and W gooseneck hitches and no a standard set of fifth wheel rails like it sounds like you have/were describing. The Patriot hitch from B and W is the hitch that normally fits that style of rails. If the rails you have are 22 inches apart that would indicate you have standard rail kit. The Demco Hijacker for above bed rails part # DM8550035 was designed to fit this type of rail and would work great. If you have something different...

  • Fifth Wheel Hitch Recommendation for 2016 RAM 3500 Short Bed w/ Puck System Towing 2015 Cedar Creek
    Although many trailer manufacturers are now designing their trailers with the tapered fronts to be more aerodynamic and also to help increase turning clearance, our hitch manufacturers are still going to recommend using a hitch with a slider opposed to a stationary hitch. Using a slider helps to compensate for the reduced turning clearance on a short bed pickup. Since your 2016 Ram 3500 will be equipped with the puck system, I recommend going with the Curt Q24 5th Wheel Trailer Hitch with...
