Review of the Curt A16 5th Wheel Trailer Hitch


Today we're going to be taking a look at the Curt A16 fifth wheel trailer hitch with R16 slider, part number C16521. Here's what our fifth wheel hitch looks like fully installed. It's going to mount using our base rails here. It's going to allow us to tow a fifth wheel trailer. This is a six foot bed truck and if you ever towed a fifth wheel with a short bed truck, you know that it comes in handy to have a slider like we have here whenever you're making tight turns. We come to this handle and we pull out, we can turn it and our fifth wheel is going to slide back 12 inches to give us extra clearance so we don't have to worry about our fifth wheel trailer hitting our cab. The slider is a non binding slider, so no matter what angle you're pulling your trailer at, it's going to be able to slide freely back and forth.

Whenever we're done making that tight turn and getting around the corner, we can straighten our trailer out, straighten our truck out, and our slider's going to slide right back and lock into position. The jaw here is a two piece jaw. It's going to make full 360 degree contact with the kingpin. If we come to our tethered handle over here, we're going to have a safety pin that's going to make sure that our handle is locked in the closed position or if we open it up and we remove the pin, we can slide our handle back and it'll open up our jaws. Another nice feature is right here in our jaw, we're going to have built in grease zerks so that way whenever we need to do maintenance on our fifth wheel, it's going to be that much easier just to reach them right there. The head itself does articulate backwards towards the front and left and right which is going to come in handy because it's going to make it easier to hook up to your trailer even if you're on un-level ground. Here on the side, you can see that we have multiple hole locations, as well as on the head itself.

This is going to be able to determine how high you want your fifth wheel head to sit. It's going to go all the way from 17 and a half inches all the way up to 21 and a half inches. Now a nice feature that's also a safety feature, is right here at the back of the head. If we look we're going to have a green circle right here in the middle. If we look over to the right, it's going to tell us that we're ready to tow. Depending on where the jaws, if they're locked open, if they're in the couple position, what position it's in, this dot here is going to change and it's either going to be red saying, you're uncoupled, do not tow, green, you're good to go, or yellow saying that you need to couple or it's not fully locked into place. Our slider also has a color indicator.

Here on the passenger side it's letting us know the green indicator means it's ready to tow. If you see this green piece sticking out, our slider is locked in the tow position. If we come to the driver side where the handle on our slider is, we'll see that there's a red stripe and this sign right here next to it is going to say red indicator, do not tow. That's letting us know that it's not locked into the towing position but it is able to slide into the maneuvering position. Our hitch is going to feature 16,000 pounds of gross trailer weight rating and the vertical load limit is going to come in right at 4,000 pounds. Now, I do want to mention, you always want to double check with your vehicle's owners manual to make sure your truck can handle that.

Now, our fifth wheel slider here, it is compatible with all industry above the bed rail kits. Now, the safety pin that goes into our handle here, we also have the option of putting a padlock here, that way our trailer is secured to our hitch. Now that we've gone over some of the features, let's show you how we get it installed. I already have my slider in place, now the way it's going to attach to our rails and our bed here, is we're going to have a couple pins and clips and on each corner it's going to go through. Going to take my pin, slide it through, now I can secure it with my cotter pin. Now that we have this in place, we're going to go ahead and put all of them in place. To begin the installation on our head, we're going to take the handle assembly here. We're going to slide it onto our handle, but before we slide it all the way on, we're going to take the spring that they provide in our kit and we're going to slide it into this slot, into this section right here. We're going to hold it with our finger, that way we can slide the handle over the spring and we can line up our holes here. We're going to need to get a bolt through here. The trick to get the spring to move out of the way without having to finagle a screwdriver or anything like that is if we take our handle and we push it all the way in, nice and tight, and we come back, very slowly pulling our handle back and we'll get just enough tension to grab that spring. Now we're going to take one of our supplied cap bolts here. We're going to drop it down into position and we're going to pull the handle back slightly so we can line up the other hole on the backside here and drop our bolt into place as well. We're going to take one of our M8 bolts here with a lock washer and we're going to slide it through. Now we're going to pull our handle back slightly to line up this hole in the back and we're going to do the same thing. We're going to take one of our cap bolts with a lock washer and then drop it down. Now we're going to take this block that's in the kit, it's going to have three holes. Two of them are going to have threads in them and one of them is just going to be open like this. Now, we're going to take it and line up the two threaded holes with our bolts and that large hole is going to go towards the large hole at the end of our handle here. We're just going to loosely line it up and then we're going to come back and using a five millimeter Allen, we're going to go ahead and start tightening down our bolts. We just want to get each one started hand tight where you don't have to worry about cross threading your bolts, and then we can snug everything up. With our handle in place, we can put our safety latch in, put the clip into place, that way our handle's locked and we can get ready to put our head into our truck bed. I have my fifth wheel on my slider now and we're going to have two holes on the front and the back of our slider. Now, each side is going to be mounted using two bolts and two lock nuts. In our application, we have a tonneau cover so we are going to set this at the lowest setting so we can go ahead and push our bolt through from the outside going in, making sure that it's going through our slider in our fifth wheel head, then we can thread on our lock nut. We can do the same thing on the back. Now that we have this side done, we can go ahead and repeat the same process on the other side. Now I'm going to go ahead and snug down all my hardware evenly before I torque down the final mount. I'm going to be using a 21 millimeter socket for the bolt and a 22 millimeter wrench for the nut on the inside. Now that my hardware's snug, I'm going to come back with a torque wrench and I'm going to torque all my bolts to the specified amount in the instructions. We're going to repeat that for all the remaining bolts. With everything torqued down we're ready to back up to our trailer and hit the road. That'll finish up our look at the Curt A16 fifth wheel trailer hitch with R16 slider, part number C16521.
