Secure Wraparound Jaw with Locking Bar

Wraparound Jaw

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 UMS hitch offers tighter tolerances around the king pin, which minimizes both rattle and chucking, for a smooth, quiet ride.


A 3/4" thick 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

Double Pivoting 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 hookup is easy because the hitch head will automatically pivot to the proper angle when it comes into contact with your pin box.


Dampeners

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 and Simple Removal for Full Bed Access

This UMS Double Pivot hitch is specially designed to fit in the underbed rails of your Ford Super Duty factory fifth-wheel towing prep package. To assemble the hitch, 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 OEM tow package receivers, 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 lower the hitch into the 4 puck receivers in your truck bed. Turn the handles to lock the feet into the pucks and secure the handles with the included safety pins. The hitch can be removed to give you full truck bed access. Simply remove the safety pins, turn the handles to unlock the feet, and lift the hitch out of the receivers.

2018 Ford F-350 Super Duty

Very simple install. Very well built unit. Had to remove 1 shim on 3 of the feet because the handles were way too tight. Had ro use a rubber mallet to turn them at first. After removing the shims, it is perfect. I purchased a small master lock to replace one of the cotter pins for the safety pins so that noone steals the hitch. No noise while driving with just the hitch installed at all. I have not had a chance to tow anything as of yet--- pick up my 40' 5er wed! Seems to be a very well made, good looking, compact hitch. This was installed in a 2018 F350 long bed dually woth the oem under bed puck system.


Comments
Fantastic after a full year of use. 5er weighs 16k and no lurching. Also very nice when parking on an un level surface... Just hook up and go! I have done 9 trips with about 5k total miles so far. It is very easy to remove-even after back surgery. Highly recommend.

Hitch is nice and makes me feel more comfortable being a more novice RV'er with the large steel bar that acts as a secondary safety, unlike one of the other big brands that just has teeth that close around the pin. Assembly took a couple hours of blood and sweat even though it really is very easy.... You have to make time to torque about 20 or so bolts, but that's pretty typical of anything you plan to drop up to 21k pounds on and jerk around all over the country. Install into/out of the truck bed is now a 5 minute project thanks to a block and tackle in the garage ceiling. Extremely easy to put in or remove as long as you have an overhead weight bearing device of some sort. Beyond my experience with dragging a 17k pound RV with it, the mfgr is VERY responsive if you call for help. I was missing 1 washer upon assembly and the sticker decal was damaged in shipping but the MFGR had new ones in my mailbox in 2 days at no charge. They are also VERY good on tech support. The only caution I have on this is make 100% sure you know what grade bolts you have and what you should torque them to. Novice mistake: I rated the bolts based on the chart in the instruction guide but I rated on head size, not the diameter and thus I over-torqued. Luckily I did not have the means to torque to the actual higher spec or I would have snapped them at 250ft-lbs. If you have any questions on correct torque, call the mfgr and as for tech support! As for usage experience: Carry a long stick with you. We end up on crooked camping sites frequently and the only issue is that while this hitch moves ALOT to accommodate, sometimes you may get up under the pin-box and you just can't get the hitch to snap shut. Having a long stick on-board will let you push on the spring-loaded part and cause it to snap closed. One last thing from experience: lube, lube, lube. Keep the thing lubed as per the manual and do not be stingy with it on the parts that slide and grab your king-pin. It helps out drastically in getting it to snap closed on the 1st try. As for lubing the top plate, everyone is using those plastic lube discs these days. They work fine BUT: They WILL cause you a bit of grief in getting the pin exactly where it needs to be to snap closed on occasion. The hitch has enough wiggle room to accomodate them but it is not 'designed' for it, so once you're 1/4" higher out of the hole than spec, sometimes you will have to play with it to get it shut. If you ever find yourself just TOTALLY unable to get it to close on the pin, put your jacks back down and pull out from under your trailer. I totally destroyed one of those plastic discs a week ago and spent 40 minutes fighting and cussing at the thing b/c it wouldn't close on my pin far enough to put the safety pin in the handle... I finally yanked the hitch out from under the trailer and I had caught the lube disc at an angle on the 1st try and it had ripped a gash in in. That extra misplaced material up under there was preventing me from being able to secure the pin. Aggravating: Yes. But I kinda like it. You will KNOW that there is an issue with your current hitching job with this thing. It can be unforgiving at times but when I have $80k of truck and $110k of RV depending on it, I'd rather it be unforgiving and tell me in a loud voice: "You screwed up your mount attempt, try again" than to get to the end of an entrance ramp and have the trailer come down on the truck bed. If I had to buy one again, I'd buy the same one.

2016 Ford F-350 Super Duty

The safety features of this hitch were exactly what my husband was looking for. We have a 2016 F 350 with the factory cutouts and this dropped right in and locked in with no problems. You do have to put this together which is fairly simple. The only complaint I had was throughout shipping, there were holes ripped all throughout the boxes. One of which was the one that had the nut's bolt's and washers in it and they weren't sealed in the bag that they came in so, we didn't have all of them. Many were lost but they were easily replaced at the local parts store. We haven't towed with it yet but everything should be typical with that.


Comments
Still very satisfied with the fifth wheel. Weve towed our 42ft fifth wheel with it several times without any problems with the hitch. Hopkins up and unhooking with no problems at all. We would highly recommend this product.

2017 Ford F-450 Super Duty

I haven't towed with this hitch yet so I'll update this when I do. Shipping was faster than I expected. It shipped in two boxes and both arrived at the same time and in good shape. Assembly took about an hour and was pretty straight forward. The included instructions are a bit vague but if you have just a little bit of mechanical knowledge and some tools its easy to figure out. I couldn't find any torque specs in the instructions but after doing a little research on the internet I found there isn't an actual spec, only make sure the bolts are good and tight, but not overly tight.

This is better than I thought it would be. It came in three boxes and you have to put it together but the instructions are easy to follow. It is totally height adjustable so you don’t have to worry about whether it will be too short or too tall for your truck bed. Second product I bought from etrailer with no complaints.

One year down and I am going strong with several more in the future! I have no complaints with this hitch. I recommend it to everyone that asks about it. Thanks again.

Review from a similar Hijacker UMS in Fifth Wheel Hitch


Having owned and used the 2005 predecessor to this hitch, I can say it's done well for us. I am hoping that this new clamshell design will make connecting to our 5th wheel toy hauler even easier. We've never invested in a hitch cover for the old one and only travel about 5 times per year. The hitch is always in the weather. We plan on covering this one as the rain washes away vital lubrication and the sun evaporates said same. This has made operating the old slide bar type hitchhiker a pain from time to time. I was disappointed in the packaging for shipment. There were three separate cardboard boxes, two of which had parts either penetrating out through the sides or in the one case, a bag of bolts falling out upon delivery. I would have liked to see better operating instructions included in the box. There are parts lists and schematics for each of the separate assemblies, but nothing aside from the stickers on the hitch on how to properly use and maintain the hitch.

The hitch functions great but the finish is peeling off in places.

Review from a similar Hijacker UMS in Fifth Wheel Hitch


First, thanks to Christina for the service and information re hitches and selection.Ok now for the complaints..... they are few. THE instructions are poor at best and the description details are misleading. They state no drilling required other than the truck bed. While I am sure this is true for 2010 trucks and newer, not so for my2007 F350. Not stated in the description is the fact that older trucks require 4, 1\2 inch holes need to be drilled in the truck frame rails. No big deal but be prepared to drill them if your truck is an older mod. Ford. Came in four boxes, each with its own set of instructions... What I was looking for was a Start Here point. That didn't exist so it was guess work for a starting point. Referring back and forth to different sections for what to do. Once I got past the slight confusion ,assembly and install was pretty easy. Took about 4 hours start to finish. Haven' towed with it yet..... that happens later to day. Good stuff. The hitch is well made and Quality seems to be outstanding. It works just as expected easy to place the hitch in the truck and comes out easily too nice clean bed after removal. If it weren't for the instructions this would be 5 star rating.

Review from a similar Hijacker UMS in Fifth Wheel Hitch


Hitch appears to be well-constructed and sturdy. I have not yet installed it. Some assembly is required, and the instructions aren't crystal clear. Better illustrations would be helpful. The videos online are the best source of installation information. Shipping materials lack protection. The powder coating was damaged in a few locations, as well as the instructions. I expect the hitch will operate exactly as designed a long as I protect the exposed parts from the inevitable elements. Rubber grommets would be a nice addition to the holes drilled in the truck bed.


Comments
Hitch is a bit tough to remove and install, so I recommend getting it exactly right the first time. It should not require persuasion to put it in place. Keeping the plugs in place helps ensure crud doesnt invade and cause issues. Other than that, it pulls the load every bit as advertised.

Great unit and help from etrailer. We sold the 5th wheel that had a sidewinder hitch on it. We are buying a 2017 Keystone Cougar RLSWE now. Will this Demco work on it? Thanks

The Demco Hijacker is compatible with any standard pinbox, and should work well with your new fifth wheel.

Review from a similar Hijacker UMS in Fifth Wheel Hitch


Our Demco hitch installed with out issues. We didn't use it till the last of May, then we pulled over 3000 miles. the only issue we had was un-hitching with hitch & 5th wheel in a semi-bind, NOT the hitches fault. Totally satisfied with the unit. We have had Demco tow bars for years before our 5th wheel, so we were not surprised at the quatity of our hitch, only complaint would be better prep before painting/coating unit. thank you Phil Z

No chucking at all, easy assembly and maintenance. Drops in and out of the brackets easily and the latching handles double as carry handles. Weights a lot, and comes in multiple boxes, so be sure to tip your UPS guy! The bolts are all grade-5 hardware and torque should be standard based on diameter.

The Reese does have what's considered by some as the best jaw system around and Reese is the company that designed the rail kit of your truck so we know the two work very well together.

  • 5th Wheel and Sidewinder Recommendation for a 2014 Ford F-250 6-3/4 bed With Factory Tow Package
    You are correct that only certain 5th wheel hitches are compatible. The Demco Hijacker UMS Double Pivot # DM8550033 is a great choice for a standard 5th wheel hitch that will work with a Sidewinder. The Sidewinder offers 22 inches of clearance, even though this will work for what you are needing, a sliding 5th wheel hitch is a better solution for you.

  • Recommended Lube Plate for Demco Hijacker UMS Double Pivot 5th Wheel Hitch
    For the Demco Hijacker UMS Double Pivot 5th Wheel Hitch - Single Jaw - Ford Super Duty Prep Package - 21K # DM8550033, I recommend the Lippert Never Fail Whisper Disk Lube Plate for 5th Wheel Trailer Hitches - 11-1/2" Diameter # LC286160.
