Features to know about

Built to Handle the Biggest Loads: 31,000 lbs Gross Towing Weight

This hitch is a true heavy hauler. With a 31,000-lb gross towing weight rating, it’s built for people pulling large fifth wheels, toy haulers, or RVs who want absolute confidence in their setup. The solid steel construction and 3/4" thick locking bar reinforce the connection so your trailer stays secure mile after mile. When you’re dealing with serious weight, having that kind of muscle and stability under you matters.

Secure Connection That Stays Quiet: Wraparound Single-Piece Jaw with Locking Bar

The single-piece wraparound jaw completely surrounds the king pin for 360° contact. That tight fit means less rattle and chucking compared to standard two-piece jaws. Add in the solid steel locking bar that automatically engages when the jaw closes, and you’ve got a connection that feels rock solid and stays quiet on rough roads. It’s the kind of hitch that makes towing feel smooth and controlled instead of harsh and noisy.

Smooth Ride Over Every Mile: Double-Pivot Head with Cushioning Polyurethane Dampeners

The double-pivot head moves both front to back and side to side, helping the trailer track naturally when you hit dips or uneven pavement. Three polyurethane dampeners absorb road shock and reduce noise so you don’t feel every bump through the truck. It’s a noticeable improvement when you’re logging long highway runs with a heavy rig behind you.

Straightforward to Install and Easy to Remove: Drop-In Design for Full Bed Access

This hitch drops right into your factory puck receivers for quick setup, no rails needed. Once bolted together, just lower it into the pucks, turn the handles to lock it in place, and pin them for security. When you want your bed clear again, pull the pins, turn the handles back, and lift it out—it weighs 133 lbs altogether, so removing it is manageable. The four height adjustments from 16" to 19" let you fine-tune your setup for level towing without extra hassle.

It seems like a good hitch we still have snow up here so I have too wait to try it out.everything fit perfect. I think I will be very happy with it, and it was at a good price as far as I’m concerned. If someone is thinking about getting one just remember you need a torque wrench.
by:
The Demo hitch arrived first, all good, nice heavy duty boxes, I assembled it with no issues, can't wait to use it.
The Hydrastar disc brake kit however arrived a couple days later in a beat up torn box barely held together. The parts in the big box were also boxed sort of, they were all broken and torn up. Fortunately the parts weren't broken.I have never seen heavy items with such flimsy packaging. I assume hydrastar boxed it all up. I am giving 5 stars because Etrailer has great customer service, and helped me over the phone to make sure I was order the correct items for my rig.

Hitch went together smoothly and fit into the factory bed holes perfectly.Rides nice on the initial test drive.Demco could make their packaging more durable. the paint was rubbed off in one area and the box was on it's way to destruction. let's face it, this is some heavy stuff to ship around.

This product is so good I purchased 4 more for my other Chevrolet Silverado's 3500s

The assembly was quick and easy since it comes mostly assembled. Also, helpful that I have 2 torque wrenches and two 3/4 deep sockets. Nice that you can pull the pin out & remove the head when you take it out. The only problem I’ve had is it’s a little tight putting it back in the pucks. I had to loosen a couple bolts to get it back in. This is definitely manageable for one person to take in and out. Delivery was very fast (3 days) and I had it in about an hour after it arrived. I like the security Demco wrap around jaw with the lock bar and the functionality of the double pivot head with the bumpers. Also, you can’t beat the price on these. The 4 height options is more than most and another reason I picked this hitch.

Thanks for the detailed review! Glad to hear the installation went smoothly and you're happy with the features of the Demco hitch. Being able to remove the head separately definitely makes getting it in and out of the truck more manageable.

Looks great, Cody. Where are you headed to first?

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.

Went together well and quickly. Only issue was when trying to torque the first bolt to spec it snapped. Other than that, nice 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.

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

by:
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.

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.

by:
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.

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.

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.

by:
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.

by:
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.

Product still works great. Been almost 2 years and many thousands of miles. Product still looks great as well. Great job Demco.

by:
Other than the logo sticker being upside down the hitch is great. Demco is sending a new one. No problem to assemble and install. Regarding etrailer.com, what rating is above excellent? Pat C in customer support went above and beyond to address any issues and was always ready to answer any questions.
by:
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.
