Features to know about

Automatic Sliding for Tight Turns: 14" of Fore-Aft Travel

When you’re backing into a campsite or making a tight turn, this hitch automatically slides back up to 14" to give you the clearance you need between the truck cab and trailer. The rack-and-pinion gears move smoothly and precisely as you turn, so you don’t have to stop, climb out, and pull a lever. It glides rearward when turning and returns forward when straightening out, making slow-speed maneuvering simple and controlled.

Strong, Secure Connection: Single-Piece Wraparound Jaw with 3/4" Locking Bar

The wraparound, single-piece jaw gives full 360-degree contact around the king pin for a tight, solid hold that cuts down on rattle and chucking. A 3/4" thick steel locking bar reinforces that connection once the jaw closes, automatically locking the trailer in place. It’s a setup built to tow heavy 5th wheels confidently at up to 21,000 lbs GTW and 5,250 lbs vertical load.

Smoother Ride on the Road: Double-Pivot Head with Polyurethane Dampeners

The double-pivot head moves both front-to-back and side-to-side to help absorb road shock and make hitching easier. Three polyurethane dampeners cushion the movement to reduce noise and jarring, so every mile feels steadier and quieter. The head naturally pivots into position as it meets the pin box, helping line things up fast when hooking up.

Simple Setup for Towing: Adjustable Height from 15-1/4" to 18"

This hitch comes pre-assembled for quick installation on the included above-bed rails and brackets. You can set the head height at 15-1/4", 16-1/2", or 18" to match your trailer setup and maintain good bed rail clearance. Once in place, pin it to the rails using the safety pins provided and it’s ready for towing—solid, level, and secure.

Video Transcript for Review of Demco Fifth Wheel Installation Kit Custom Brackets - DM8552030

Hello, neighbors. Steve here with etrailer.com. Today we're looking at the Demco Premier Series custom mounting brackets for your 5th wheel above-bed base rails. Now folks, this is a custom-fit application. Those bed rails when they're installed would look something like this. Again, those are sold separately.

That's part number DM6071. And again, those will sit in the bed and allow the installation of your fifth wheel trailer hitch on top of them. Again, the brackets today, folks, are custom and they mount beneath the bed of your truck to provide that attachment point for those rails. Now folks, this is a custom-fit application on the brackets. They're fitting between 2009 through current year RAM 1500 and Dodge Ram pickup trucks, all bed lengths.

But please check the fit guide, etrailer.com, top center of the homepage. Make sure you're getting the right parts for your specific vehicle. It's gonna ask you for year, make, and model, cab length, bed size, truck size, those kind of things. Make sure you're getting the right parts the first time. That being said, folks, the custom brackets again, are gonna mount to existing holes in your vehicle's frame.

It's gonna minimize drilling to very, very little. That's gonna reduce installation time and it avoids known obstacles along your truck's frame. It's a nice, sturdy, heavy-duty, steel-coated, black powder coat. It's gonna resist corrosion, rust, that kind of stuff. As you can see, all the brackets are marked.

Let's see, driver, passenger, rear, rear, the side ones. You got the front passenger and the driver front passenger. Or driver front. Different shapes on these front ones. So just a quick view of those. And again, you're getting all the mounting hardware. You get a couple fish wires here included. Those are for threading the bolts onto there and pull it through the frame. You got some lock tight included or blue thread lock. You get all the hardware, again, as I mentioned, needed to install this directly into the frame of your pickup truck. Everything's made here in the US. It's got a great five-year limited warranty. And again, folks, these do work with the base rails, and those base rails are sold separately. Part number DM6071. Well folks that's gonna wrap it up for our look at these Demco Premier Series custom mounting brackets. I'm Steven, thanks for watching.

  • Which is Better Auto Sliding Fifth Wheel Hitch for 2019 Ram 2500: Pullrite or Demco
    For your 2019 Ram 2500 short bed with the factory fifth wheel rail kit I recommend the Demco Hijacker autoslide part # DM8550034 for an 18k hitch or part # DM8550035 for a 21k hitch with the adapter plate part # DM6099 over the Pullrite hitches for a few reasons. The hitch head on the Hijacker has built-in brackets that hold it to your pin box since it needs to lock to the pin box as you make turns to allow the slider mechanism to automatically operate. The Pullrite option requires purchasing...

  • 5th Wheel Hitch Options For A 2017 Ram 3500 With A Bradford Flatbed
    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...

  • 2500 or 3500 Series Truck Recommendation for Towing Trailer 14,500 lb
    For a trailer that weighs, 14,500 lbs I would strongly recommend a 3500 series truck. Even if the 2500 could technically tow it the 3500's higher rated suspension will make for a much better towing experience. Less sag and a smoother ride when towing. 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. I'd also recommend a dually rear axle as that adds...

  • 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. That said, you do have a number of different options, which I'll list for you and then make my recommendation. 5th Wheel Hitch for 2020...

  • Troubleshooting Demco Hijacker Autoslide Making Noise
    How old is the hitch? Does your fifth wheel have a standard pin box or a cushioned pin box? Has it been lubricated? Does the locking bar automatically lock when the jaw closes? The thing that comes to mind immediately is the capture plates may not be adjusted properly. They MUST be evenly on both sides to 1/8" more than the width of the pin box.

  • 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...

  • 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. The only real difference between the two models is their towing capacity. The Hijacker features an automatic slider to provide cab clearance with your short bed Sierra without having to get out of the truck. It also has a premium wraparound single-piece jaw that will provide an excellent connection with the...

  • 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...

    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.

  • Autosliding 5th Wheel Hitch for a 2019 Ram 3500 with OEM Puck System
    The autosliding 5th wheel hitch we have for you to use on your 2019 Ram 3500 is the Demco Hijacker. This comes in both an 18K # DM8550034 and a 21K # DM8550035 weight rating and secures to your OEM puck system with the adapter rail kit # DM6099. The Hijacker is one of my favorite 5th wheel hitches because it not only has great cushioning for the head unit, but it also has a single-jaw system that is reinforced by a 3/4" steel bar to give you some peace of mind. All of this combined gives...

    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...

  • 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...

    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.

  • 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.

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.

If instead you didn't have the OEM rail kit you'd need the rail kit # DM39FR with the same hitch # DM8550035 and you'd be set. The Hijacker will work great with the Lippert 1621 you have now. Another great option is a fixed hitch with a Sidewinder that can fit your trailer in place of the 1621 with part # RP34FR.
