Review of the Demco Hijacker Autoslide 5th Wheel Trailer Hitch


Today we're going to look at the Demco Hijacker Autoslide 5th Wheel Trailer Hitch, part number DM8550034. We have an autoslide in a typical application. It's sitting on a typical set of rails. This autoslide will work with the major brands of of fifth wheel rails that are out there. This will couple up to your fifth wheel trailer just like any other hitch out there, with a couple exceptions. With the fifth wheel clamped into place, that will enable the autoslide to do it's job. It's designed to work with standard pin boxes twelve inches to fourteen inches wide.

Then for certain applications there's addition locking plates that are sold separately for other pin boxes, such as the Glide Ride, MOR/ryde, Trailair Tri-Glide, and the 5th Airborne. This does have a gross towing weight limit of 18,000 pounds, and a vertical load limit of 4,500 pounds. The total amount of travel going from front to back is going to be fourteen inches. Let's go ahead and hook it up to a trailer, and try it out and see how it works. If we take a close at the jaws, you notice it actually wraps completetely around the king pin. This provides a firm grip on it, and keeps it from moving around, and it actually keeps everything a little more quiet. We'll go ahead and operate the handle, and you can see the jaws open up.

To do that we'll go ahead and pull open this pin right here. We have our Hijacker fresh out of the box, so this is what it will look like when you put it all together. It's initial use we'll go ahead and pull up on the pin, this is a locking pin. Pull on the handle, and you can see how it opens up, and release it and it stays open. It will not close until you put your fifth wheel kingpin into it, and it will automatically snap into place.

The kingpin will come in, it'll push open just a little bit, and then it'll snap back into place. Once your coupled up to your trailer you're going to reinstall your safety pin. It may help if you pull the handle out just a little bit to help line it up. Our clamps are pretty easy to use. Once you have your fifth wheel engaged and locked into place, slide these clamps in until it touches. Then you have these set screws that locks it into place, having your trailer be fully connected up to your truck. Next we'll go ahead and show you the range-of-motion that's provided with this hitch.

First off, we've got left to right, and also front to rear. It looks like there not a lot of movement there, but actually there is. On each side left and right there is a dampener that makes this whole assembly as quiet as possible while going around turns, or uneven terrain. Same thing for your front and rear, there's a damper up front that helps keep it from bottoming out and making any more noise than it has to. Let's go ahead and take a closer look at what makes the autoslide tick. First off, inside here we have this set of gears right here at this pivot point. At this pivot point right here you can a small wheel here, this actually rides on this surface. What happens is when you go in straight line it's going to sit just like it is as you see it right now. Once you go around a turn, and you go far enough, this little wheel will go the opposite way of your turning, and this will allow the whole assembly to come towards the back. As you make your turn it will push the trailer away from the cab of your truck, so you don't have to worry about the cab and trailer interacting with each other. It looks like a lot going on here, but it's actually easier than you think to put together, considering there's five pieces you need to put on at the most. First part is this outrigger right here. You've got the two threaded rods that go onto this plate right here. A couple of nuts to lock it in place, pretty simple stuff. Our next part will be the side brackets right here, which get bolted to the side of the Hijacker. It takes only four bolts that hold it in place. To put it together it only requires a 3/4" wrench and socket. This provides three levels of heighth to match up to your trailer. In this case here, if you notice we have this edge flush to the top here, we have it in it's highest position. You can see how the bracket will interact with the fifth wheel rails that we're previously installed on the truck. It uses plain conventional pins and clips to help hold it is place, and it does come with these pins and clips as well. The main part will be the head assembly right here. Basically, there's a pin that goes throughout the bottom here, that uses a clip on this side, and you may need extra hands to help install that into place. Really no tools required for that part. The last part will be this handle that gets bolted on right here. All that requires is a 9/16th socket and wrench. That will finish it for the Demco Hijacker Autoslide Fifth Wheel Trailer Hitch, part number DM8550034.
