How to Install the Curt Fifth Wheel Kit on a 2017 Chevrolet Silverado 2500


Today on our 2017 Chevrolet Silverado 2500 we're going to be taking a look at and installing the Curt Custom Fifth Wheel Installation Kit, part number C16411-204. So here's what our rails look like fully installed. They're going to allow us to mount a fifth wheel trailer hitch and pull a fifth wheel trailer. And when we're not towing with our fifth wheel, we can go ahead and pull the hitch out and with the hitch out of the bed we're only going to be taking up about an inch of vertical space in our truck bed. Now this is a custom fit application, so it's going to cut down the installation time and require less drilling than most universal kits. These are designed to work with most industry standard above the bed fifth wheel hitches. This is also going to work well with several different goose neck adapters, which is going to be nice if you don't want to cut a big hole in the middle of your bed. It's going to feature a carbide powder coat finish which is going to complement any color truck. Now that we've gone over some of the features, let's show you how we get it installed.

To begin our installation we're going to need to take a few measurements. The numbers are in the kit in the instructions and depending on whether you have a long bed or a short bed truck, those measurements might be a little bit different. So I'm going to go ahead and make a few marks so I know where my measurements are. I'm going to go across the bed, that way I know it's going to be nice and level. Now that we have our measurements marked out, we're going to take the flat edge of our rail here and we're going to lay it down right on where we just made those marks. And now we're going to need to measure our rail and the width of our bed and make sure that we're nice and centered.

Once you have your rail put into position, go ahead and find the center point and make any adjustments on where your rail needs to be. Next, we can go ahead and take a paint marker when we have everything centered up. I'm going to mark the outermost holes of these square holes, as well as the center one. On this bar, we're going to be marking towards the rear of the truck. With the holes marked we're going to move our rail out of the way and using a 1/8" drill bit, I'm going to drill some pilot holes where I just marked. You're going to want to try to get it as centered as you can, and we're going to repeat that with all of those marks that we made. Now we're going to come to the side of our frame here, and I'm going to take my frame bracket.

This is the driver's side. The way we're going to know the difference between the driver's side and the passengers side is with these tabs going in towards the truck, we're going to have this square cut at almost an angle. That's going to go towards the rear, and on the front is going to be more rounded. Now we're going to take our bracket and we're going to go up in between the frame and the bed, and it's going to mount right here. I'm just going to take some loose hardware and for now I'm just going to put it in the slots of the frame to hold it in position. To make sure that everything's lining up, I'm going to take my drill bit that I used to drill my holes and I'm going to poke it through, then I'm going to go back underneath the truck and make sure that I can see my drill bit going through the bracket and the bed of my truck, that way I know everything's lined up.

Once we do this for the driver's side, we're going to go to the passenger's side and do the same thing and make sure everything's nice and square. Now that we know that our rails are centered on our truck, I'm going to come back with a step drill bit and I'm going to drill out the pilot holes that I drilled out to a 9/16" hole. Now we're going to drill all the rest of the remaining holes out as well. We're going to take our frame bracket again now that the holes are drilled out and loosely put it into position. Now we're going to start out with an M14 bolt followed by a 5/8" lock washer, and finally a 5/8" flat washer. Now we're going to raise this into position and if we look at our frame, we're going to have an oval hole towards the front. We're going to be using the threaded hole here and lining up our two holes in our bracket with these two holes. So we line up our bracket. We can take our hardware and loosely put it into place. Then we can come to the back threaded hole and put our rear hardware in. Now we can do the same thing on the passenger's side with our passenger's side frame bracket. Now we can come back into our bed and we're going to take our mounting bracket here and we're going to line it back up with the holes that we drilled. We're going to take our hardware and take a 1/2" carriage bolt and put it through our bracket. Before we do as you can see here on the edge here, our hole is actually below the rib. They provided us with some spacers and we're just going to slide it underneath. That way when we put our bolt in we won't have to worry about crushing the bed, crushing the ribs on our bed, and it will give us some extra support. So anywhere that he rail is not perfectly flush with the rib, go ahead and put that spacer in and we're going to put our carriage bolts through all the holes that we drilled. Now with our first rail and hardware in place, we're going to come underneath and we're going to take one of these square spacer blocks followed by a 1/2" flange nut and we're going to tighten everything up with our hardware coming through. It might be a little bit hard to see, but this is going to be the end result with a plate underneath and our flange nut holding everything in place. Now with that one in place we're going to put the rest of our hardware and all the other remaining bolts. Our center bolts here, just like I mentioned before, is in a middle section of the rib. So underneath we're going to take our spacer block, we're going to go around the bolt like that, then we're going to come back with the square holed spacer and we're going to put it on top of that. And then finally we're going to tighten it up with a 1/2" flange nut. We're just going to put everything loosely in place right now so we don't have to worry about our hardware falling out. Now that we have our front mounting bracket and our frame brackets in, we went ahead and put our fifth wheel in that we're going to be using and that's going to determine where our second mounting plate is going to be mounted. What we're going to do is we're going to lift up on here and put it into the slots on our other bracket towards the rear. That will give us the exact location and then we can mark and drill our holes. Once we have our fifth wheel in place we want to make sure that our mounting bracket is square with our truck bed and it's not crooked or misaligned. We're going to go ahead and mark our holes. With our rear plate here, we're not going to be using the outermost holes, we're going to be using the second ones on the inside. If we come to the center, we're going to be using the hole that's closest to our tail gate. Now that we have all of these marked out, we're going to go ahead and lift up my fifth wheel and slide this out of the way so I can go ahead and start drilling my holes. I'm going to go ahead and drill my pilot holes again, and then I'll come back and enlarge them to a 9/16" hole, just like we did with the front rail. With the holes enlarged and drilled, we can go ahead and put our rail back in place. And again we want to make sure that our holes line up. If we need to we'll go ahead and use our spacers, but since this is on the rib we can just go ahead and drop down our hardware into the hole. Now we're going to put our hardware in place just like we did with our other bracket. First we're going to have our U-shaped spacer go around our bolt, followed by a square holed spacer, and then finally we're going to follow it up with our 1/2" flange nut. Again we're just going to put all of this hand tight for now, just so we don't lose our hardware. Now we can do the hardware on the sides. Now on our side plate we're going to take one of our square plate washers here. We're going to go up over the stud and then we're going to follow it up with our 1/2" flange nut. We're going to repeat the same process for all the remaining hardware. On the rear here you can see there's quite a bit of a gap on our plate here. To prevent the ribs in our bed from crushing, we're going to take more of those U-shaped spacers and we're just going to slide them into place right around our bolt. That way when we tighten it up we don't have to worry about crushing the ribs in our bed. With everything loosely in place we're going to come back and using a 3/4" socket, we're going to tighten down all my half inch hardware to the specified amount in the instructions. We're going to repeat that process for the remaining hardware we have left. When all of our 1/2" hardware underneath are truck torqued, we're going to come back to our M14 bolts here and we're going to torque them down to the specified amount in the instructions. We're going to repeat that process for all of the remaining hardware. And that will finish up our look at the Curt Custom Fifth Wheel Installation Kit, part number C16411-204 on our 2017 Chevrolet Silverado 2500.
