Hi there Silverado owners. Today on our 2018 Chevrolet Silverado 2500 we're going to be installing Demco's Underbed Rail Installation Kit for the Demco Hijacker 5th Wheel or Gooseneck. If have a gooseneck trailer, the underbed rail kit will also work with Demco's Hijacker Gooseneck Hitches. This underbed rail kit is going to allow you to install a Demco 5th wheel or a gooseneck hitch on your Silverado.With your new 5th wheel or gooseneck hitch installed you can haul that toy hauler, or 5th wheel trailer that you've been wanting to haul, or you can go ahead and put it to work out at the job site. The rails will work with any Demco Hijacker 5th wheel or gooseneck hitch. You'll want to make sure you pick the appropriate hitch for your needs.One of the things that I really like about this kit is that it installs underneath your bed so when you take your 5th wheel or gooseneck out you have a nice clean look.
Unlike raised rails that will stick up above your bed.I also like how easy it is to install. You use the existing holes in your frame so there's no drilling required, which really cuts down on the install time and the amount of fatigue you're going to have putting it in.Another thing I really like about this kit is that it'll allow you to use the Demco Hijacker 5th wheel, which works out great for tighter turns than you'll get with other ones. Especially if you have a short bed truck due to it's auto slide feature.We'll begin our installation in the bed of our truck by marking out the locations where we're going to drill to install our underbed rails. These measurements are going to vary depending on the length of the bed of your truck so you'll want to closely look at those measurements and mark it out like we've got here. You'll find specific measurements for your truck in your instructions.Well now I need to drill four holes using a two-inch hole saw.
We're going to do it at each corner where we marked. You can see this in the diagram in your instructions. We'll now repeat that for the three remaining holes. With all of our holes drilled out we can clean up the metal shavings now. Then we'll use some clear coat to prevent any rust and corrosion around our exposed metal where we drilled.
You can use some general purpose cleaner to clean off any of the markings that you made when determining where your hole location should be.Now that we've completed all the cutting we need to do in the bed, we can begin mounting our underbed rails. We're going to start with the side rails that are going to mount onto our frame here. Your rails are going to be labeled. We're on the passenger side. We've grabbed our passenger side side rail here.
We'll be using four of the longer bolts that come in your kit with hex heads. We'll then prepare these by placing lock washers and flat washers on them. We'll have four like this, for each side, prepared to install the rail onto the side of the frame by setting it on there and matching up the holes that's already existing in your frame, with the holes on our side rail. You'll see it's already got weld nuts in it. You simply take your bolt, slide it through and thread it into the frame. We're going to do this with the remaining three holes that have weld nuts. We'll repeat this on the other side.For our third holes that don't have weld nuts, we'll use the fish wire provided in the kit. We're going to go through the hole until it comes out the other side of the frame. You might have to finagle it around to get it through the other side. Then on the other side of your frame, we're going to slide a spacer over our fish wire. Then thread one of the carriage bolts, that come in the kit, onto the fish wire. First you'll feed in your spacer, then your bolt, then we'll just pull them through till it comes out the other side. Once you've got it pulled through, we'll place a nut on this side. We're going to repeat this with the other hole on this side and the two on the other side.You'll receive blue Loctite in your kit. You want to make sure you put some of that on all of your bolts.Next we'll be sliding our cross rails from one side of the frame across to the other but in order to get them to fit you are going to have to cut out a small section here. You don't need to cut it completely out. We're actually just going to cut it straight up. We're just going to go up like this. We're going to just be doing this around the section where you see the slits in your side rail. You want to make sure it's wide enough to fit your cross rail in. It's about three and a half inches. If you cut it there you could check to see if it'll fit. You may need to notch the sheet metal here at the bottom as well, in order to get it to fit.Now if it does get tight when pushing it in, you may need to loosen the bolts to your truck bed to get the extra clearance or if it's really close, like ours is, you could just take a piece of wood or a rubber mallet and tap it in. We're going to do the exact same process for our front rail. With both of our rails in place we can take the hardware that comes in our kit. We're going to be using the shorter large diameter hex head bolts with a flat washer on it. This is going to slide up through our slide rail. We're going to place a spacer plate underneath the rail. This has got to go through the front most hole, through the side rail, through your spacer plate and then into your cross rail. On the top we're going to place a nut. We're going to repeat that for the three remaining holes for both of your cross rails.We'll now tighten down all of our hardware using a one-inch socket. You may need a one-inch wrench to hold the nuts on some of them. Before you torque everything down, it's not a bad idea to take your 5th wheel, set it onto your base rails, to make sure that it's going to line up properly. If everything then you can go back and torque all the hardware to the specifications found in your instructions. If your 5th wheel doesn't fit you may need to loosen the hardware and slightly shift the rails until it lines up. Now with your rails torqued down you can install your Demco 5th wheel or gooseneck and hit the road.That completes our installation of Demco's Underbed Rail Installation Kit for the Demco Hijacker 5th Wheel and Gooseneck on your 2018 Chevrolet Silverado.

The instructions provided with the hitch were very detailed and provided enough information for me to install it myself. I love having the mounting rails below the bed. the auto slide worked flawlessly. For the winter I left the hitch coupled with the trailer to keep my bed clear.
Merchandise arrived in good condition. Nothing missing. The shipping carton was in terrible condition. It was torn open from shipping, however nothing was missing or damaged . The product will fill my needs to replace the above bed rails that don't leave a clean bed when fifth wheel is removed. This will fill the bill. Thanks to Etrailer this will work perfectly for my Demco hijacker fifth wheel. Shipment was quick delivery.
Kit made for my rig and fit as described. Installation a little on the difficult side for your typical DIY'er.

The under bed kit is the best. Having the truck bed useful when not traveling is great. I use a small electric hoist and casters for lifting and moving so the weigh is no problem. Installation was a little on the difficult side but any experienced DIYer can handle it.
First package was destroyed in shipping, all hardware was missing, called etrailer forgot her name ( sorry ) very polite. she ordered all the correct hardware needed and had it shipped out. Except for the shipping was very pleased with etrailer.
Once I mounted everything and figured out I had to switch passenger and drivers brackets everything was fine it worked out ok
It arrived in two days. Great delivery.
I like it’s design and how it sits in the bed. It seems to want to rotate some while pulling. I see some reviews that other people are having this problem also. Some have put a bolt down through the base into the truck bed. I haven’t wanted to do that as of yet. Otherwise I like the hitch.
Parts arrived for the DM 8550043, received only the hitch base plate and adjustable shaft for the hitch head. Have been told that the hitch head is shipped separately. Now have a problem with the hitch plate fitting the bed rails. The holes for the pin that secures the hitch plate to the rails are to close to the bottom of the hitch plate photos are given of the problem a pencil was used for reference. There is NO WAY the pin will go through the rail and hitch plate. Waiting on a solution from etrailer. The hole that you can barely see the pencil is tailgate rails pin fits fine.
The hitch took about 45 minutes to put together. Including putting on the side plates. I wanted the extra two inches of travel that the Recon gives you over the competitors. I would have gone with the auto slide but there was not a adapter plate to fit my old nine inch wide pin box.
The truck that got the install is a 2002 Ford F350 Super Duty 7.3 L Diesel dually. The Demco Recon 5th wheel hitch (DM8550043) looks like a well made, heavy duty hitch. All the welds are precise and well done. I like the single wrap around jaw with the real thick bar that backs that up. The handle that pulls out to unlock the jaw moves with ease and locks in the out position when the jaw opens. When the king pin comes in contact with the back of jaw, the jaw wraps around the king pin, the handle closes, you put in the safety pin and your ready to go RVing. I chose the Husky Custom Rails and installation kit (HT31405-686) for my install. The reason I chose these rails over the ones that etrailer had matched up for the hitch is, I had previously installed a set of Airlift Airbags and I didn't want the rail install to interfere with the airbags. It was a good choice, there was no interference at all. If I had not had the bags, I would have chose the rails and install kit that require no drilling. Drilling the holes went very fast and easy, it was torking the rear bolts down that was very difficult. There was not enough room to get a wrench of any kind around the nut. I wound up using a set of vise grips on the nut while a friend of mine torked the bolt slowly from above.
All and all I'm happy with the product and I'll give another review in a year.
Excellent product and customer service was outstanding. I just bought the product so I haven’t towed with it yet but after many many years of towing with other fifth wheel hitches, I can tell this is going to be an huge improvement!
very good product although when unhitching rv it wants to trip the latch. I had to address that problem by drilling a hole in the trip bar for the pin to hold it open.
The only issue I am having with the fifth wheel hitch is latch handle will not stay open (out) when hooking up or disconnecting from king Pin sometimes (and yes, I know how to work a fifth wheel hitch). If it wasn't for that I would give it 5 stars.
This hitch with the Airbourne Sidewinder worked great with the 2018 Ram 2500 Mega cab short bed with Ram boxes. Can maneuver a 90 degree turn without issue. Still have to get trailer lifted higher to get the trailer nose lowered, but for the complicated research we had on the right combo, this is tested and verified
Rugged product, easy to install, quick latch system. easy to remove. Purchased the Reese adapter with this hitch, and installation was easy. Some minor adjustments with the cam over lugs, and setting the hitch posts into the adapter. Overall very easy set up. Looks good, and can be taken apart in pieces, for ease of removal and installation, after set up. Ordering was simple and all parts came in about a week.
Ordered hitch late Wednesday evening and received early afternoon on Friday, that is super fast delivery. Two cartons received with no damage and all parts were there as expected. It looks exactly as advertised online and it was at a great price. AND FREE SHIPPING.
Also made in the USA.
I am replacing my Demco Hi Jacker Auto Slider that weighs approximately 300 lbs with the Demco Recon that according to the shipping labels weighs 91 lbs. It will be installed on a Ford F150 with 5 1/2 ft bed and fiver with a Lippert Turning Point Pin box.
Easy to set up and use I borrowed a buddies cause I bought a camper and didn’t have a hitch set up in the bed of my truck just had the goose neck ball pulled real nice so I order o e just like it

That is because this product only fits vehicles without The OEM Prep Package. You want something like this: Item # DM6194.
