Video Transcript for Set up: Curt Custom Fifth Wheel Installation Kit for Chevy/GMC on a 2016 GMC Sierra 3500

Today on our 2016 GMC Sierra 3500, we're going to be showing you how to install the Curt Custom Fifth Wheel Installation Kit with carbide finish. Part number is C16411-204. Here's what our rail kit is going to look like installed. These do a great job of offering us the ability to put in and take out our fifth wheel without taking up a whole lot of room in the bed of the truck. From the high side of the corrugation on the bed to the top of the rail, we're only looking at about one inch. Not a whole lot of room being taken up there.

That's going to allow us to get this thing in and out when we need it. As far as installation goes with it, it was really straightforward. You've got five bolts in the rear rail, five bolts in the front rail. The bolts weren't that terribly difficult to get to to put the hardware on, so in pretty good shape there. This offers the custom bracket. These are designed to fit specifically on our frame using, in our case today, existing weld nuts.

If you've got a little bit older truck, you're going to use carriage bolts that you'll draw through. Either way, it's not going to be that big of a difference one way or another. It allows us to get these mounted to our frame without having to do a lot of drilling, coming up with our own game plan kind of situation that you get usually with those universal style of rail installation kit. It really cuts that job time down in about half. You can get it in your truck, you can get back to work without having a whole lot of downtime. You can see we've got the Curt Q20 mounted in the rails now, but we do have the narrower slots and the wider slots, which will help these rails fit a very wide variety of fifth wheel products, and even the gooseneck heads that'll fit down in the rails, be able to be pinned in that way.

Gives you a lot of versatility with the system. Able to use several different heads with the same set of rails. To begin our installation, we need to get our front rail locked into position so we know where we're going to start our holes. In your instructions, they're going to give you measurements for both the long bed and the short bed. You want to use those. We're going to measure from the rear of the truck bed forward and get it set in the appropriate position.

When you do this, if you do have a bed liner, you need to add on the thickness of that bed liner just to keep everything as it should be. Once that's set, we're also going to need to center it side to side. I like to use this little lip that's right here. Just measure over, see what you've got from side to side, and make adjustments as necessary there. Check your measurements one more time, and then we're going to mark the first couple hole locations here with a center punch. For the forward rail, we're going to use two outside locations here. Before you go too far, something I like to do is use a paint marker and mark those locations, because on these spray in bed liners they can be hard to see. Now we'll use a 1/8th inch drill bit. We're going to go down through, free drill our holes. We will want to ensure that we only go through the bed. There can be things underneath that. You'll want to check to make sure there is no electrical harnesses or anything like that you might hit. Now we're here in the wheel well area. If equipped with this fender liner, you want to get that removed. There's going to be 13 screws, just kind of like this. You got two here, and then they go up and around here. You'll want a T15 torques bit for them, and just get them pulled out of there. We're going to put this back in later so you want to hang on to them for sure. We'll set that aside, and we'll go do the same thing over on our passenger side. Now we'll raise our side plate up into position here. We're going to use our M16 bolts and just a flat washer. This is just going to be temporary so we can check our hole location. We want to screw in that down hand tight so it holds that side plate in position. We're going to do the same thing for the forward attachment point here. Now we'll either use a skinny screwdriver or that same drill bit we did before, and we want to poke it down through the holes in the bed and ensure that it comes out in the holes that are in our rail here. Here you see we've got good clearance. We can move that screwdriver all the way around so we shouldn't have any issues in getting our bolts put down through there. We'll enlarge our holes to the appropriate size. It's a good idea, once your done, to get these scrapings vacuumed up so you don't drag them all around the bed of the truck. Of course, we'll also position our rail, slide our bolts in, and get the middle hole drilled. Now our side plates can go back into position. We just need to ensure that this time we have that lock washer as well as the flat washer in place when we do that. We'll snug these down hand tight. Do that on both sides of the vehicle. With those drilled out, we're ready to get our rail put back into position. We've got U shaped spacers. These are going to go on the non-raised side of the corrugated bed. In this case, this is in the valley so we're going to place them right down on there. That's going to prevent us from crushing the bed when we get everything tightened down. In the case for the middle location here, this would be on the raised portion so these spacer will need to go on the bottom. You just want to keep this in mind as you're putting them in place. We're going to do the same thing on the rear rail. Select whether they should go on the top or the bottom when you get it installed. We like to remove the spare tire, and also take the heat shield down. Just gives you some more room to work. That's not necessarily a requirement for you, but it might make it a little bit easier for you to get to your hardware. If you do decide to take down the heat shield, you'll need a 13 millimeter socket and about a 10 inch extension. You got one bolt right here, and then also one right there. Here at our center location, we've got our U shaped spacer there. Place that up in our . We'll still have our spacer block there. I'm just going to tighten these down hand tight for now. Now we can go around to the other four locations, and we'll just be putting on our spacer block there, and flange nut. Now we'll get our hardware snugged down and tightened up to the specifications listed in our instructions. We'll do that for our four other locations as well. With our front rail nice and secure, it's time to find the position for our rear rail. To do that, you're going to need the arms from your slider or your fifth wheel, whatever accessory you're going to put in here. You want the arms. Now whether it's assembled or not assembled, that's going to be up to you. It's easier to do it when they're not assembled. You want to put them in the outside of the brackets here. What we're going to do is pull as far forward on this rear rail as possible. That's going to give us as tight of a fit as we can get. It's going to help to reduce noise and other things like that. We also want to make sure that we're centered between the bed inaudible 00:08:52. That we've got it centered in our bed. That's the position we've got it in now. We're going to mark our holes. The middle hole is going to be in the same location. It's going to be right in the rear of the rail. Get that one marked. When we come to the outside of the rail, that's where it's going to change a little it. On the front rail, we use the outside hole here. When it comes time to do the rear rail, we need to do the second from the outside set of holes. Make sure that we either get a center punch or a mark in there right dead center in the whole, then we can move that rail out of the way, make our 1/8th inch pilot holes, check to make sure we don't have anything in behind the bed, and then finish them up with that 9/16th inch drill bit. Now for our second rail, we can drop all of our bolts down through. Our spacers are going to go on the bottom, so we don't have to worry about the U shaped spacers on top. Here you'll see our rear bolts where they come down through. Those U shaped spacer, we're going to slide those right in so they'll go around that bolt for us. We've got our spacer that goes on the bottom with our flange nut. For the middle location, we'll do it just the same as we did the front rail middle bolt. You just want to go around to get all five of them secure, and we'll start torquing those down. With those rails secured down, it's time to tighten up side plates here. We're also going to have a specification for these bolts listed in the instructions that we'll want to follow as well. We'll do the same thing on our passenger side. Now we get our fender liners put back in here if your truck was equipped with it. Just need to pop them in around the edge. Once we have it all popped in, we'll work on making sure our holes are lined up properly. We'll put all our fasteners back in place. With everything back in place, that's going to complete our installation of the Curt Custom Fifth Wheel Installation Kit, part number C16411-204, on our 2016 GMC Sierra 3500.

I had originally ordered a 11604/11607 under bed gooseneck mount for my 2019 Silverado 2500HD, but found out during initial parts fitting that an under bed rib had been welded out of position on my truck, and the side rail brackets would not fit because of it. A phone call to Curt verified my finding and they suggested going to an in bed rail mount as an alternative. I called etrailer and spoke with Bailey B about my situation and she was very quick to understand what I needed to do. She helped me place an order for a 16411/16204 in bed rail mount kit. She then emailed me instructions and UPS shipping labels so I could return the parts I could not use. I received my new kit yesterday (one day early!!) and a quick look tells me I now have what I need. Bailey B was super helpful, and the exchange process was above and beyond my expectations. Count on me for future purchases. I had hand surgery a few days ago so it will be a while before I can install this hitch rail kit. If I can edit this review then, I'll add pictures. In the meantime, I'm going to have a spray in bed liner done and I'll be ready to go. Thanks again Bailey and etrailer!

Fantastic! I was able to install the entire kit by myself as soon as my hand allowed me to. Everything went together as it was supposed to. Ive only been able to tow my 5er a few times, but getting hitched up and unhitched is a breeze, even when the truck isnt straight on to the trailer. The hitch is totally silent, with no chucking at all. I was able to set it up so I had good cab clearance that I dont need to use the Turning Point feature on my pin box. I highly recommend this hitch.

Just installed my curt 5th wheel kit,all materials are heavy duty and comes with all hardware needed. Installation is straightforward for the average DIY . The only challenge in the installation of the kit is getting the right tool to torque the rail bolts. My truck is a 2013 chevy Silverado 2500HD. I would recommend this kit.

After using my equipment for a year, I honestly have nothing bad to say. The product holds up in the elements and great quality. Thanks again!!

I feel that the installation video simplifies the process to much. Attaching the frame plates with the bolt fish wire was more difficult than the video showed. I am to blame for the first bolt. We started on the left side and fished the back bolt first. I did not check to see if the wire would go through both plate and bolt once threaded onto the bolt. I just placed the plate on the wire and then threaded the bolt onto the wire and pulled or tried to pull it through the frame hole. The wire was "bunched" on part of the bolt and would not feed through the frame and the plate holes. I stretched the wire to the point I thought I was going to lose the bolt in the frame. We ended up getting the bolt back out and using the other fish wire to feed this bolt through. We made sure we could fit both the plate and bolt through together before fishing it through the frame. Once we did one the other three went a lot easier but we only had one fish wire to use.
I had watched the installation video several times and played it while we were working. The video is good but it makes the process seem to easy.
I would like to see the video have more details about this process and have 4 fish wire instead of 2 or tell people you may want to have two more on hand for piece of mind.

After a year and around 7,000 miles pulling our fifth wheel camper, I love the hitch. I have not had to use the sliding portion but glad we have it if we need it

The installation video is very helpful friendly service and fast shipping and very accurate fitment definitely recommend e trailer for any trailer needs and accessories

Works great, I self performed the install on my 2018 GMC, the only issue I struggled with was on feeding the bolts through the frame with the provided threaded feeder wire on the front driverside, the trucks fuel tank location and brake lines mounted on the frame was a little challenging but worked through it. Thanks



by:

Last summer I made purchase of the A16 sliding 5th wheel hitch along with rails.the install took about six hours working by myself .following the enclosed instructions is important and saves time if you do it exactly as shown.I was very pleased with the delivery,it was prompt and no charge.that was great.the hitch is a slider which I think is important on a shortbed,could save damage to truck during maneuvers.my experience with etrailer has been really good and would recommend this company to anybody shopping for trailering equipment

The installation kit fit perfect but take the time to move the spare tire and the heat shield out of the way to make it easier.

The products have worked flawlessly no problems and thank you for checking back with me its nice when a company cares about there costumers. Next time I need any trailer products I will definitely be contacting etrailer.



by:

Excellent product, perfect fit for my vehicle, arrived a couple days before it was supposed to. I did not want an "aftermarket" look, which is why I ordered a kit designed specifically for my vehicle. I did take the time to remove the heat shield to gain better access to the installation bolts. The biggest challenge was installing and tightening the bolts that go through the bed; there is not a lot of room between the trucks frame and the bed of the truck. The most challenging bolts were the ones on the driver side closest to the cab of the truck due to the placement of the gas tank. Trailer wiring was plug-and-play, hardest part was drilling the 2" hole in the side of my truck bed.



by:

Whew! Installing that Rail kit about kicked my butt! The reason why is all the trips I made from underneath the truck and back. The Rail kit is a very high Quality Product from Curt that fits perfectly in the bed of my truck. The hardware is also high quality. One downside is there isn't a lot of room to work as the gas tank on one side and the exhaust on the other side prevents easy access (gas tank in particular). It was very hard to get a wrench on the nuts unless you used a Gearwrench. After the install they are torqued to 110 ft-lb. The only way to do that was to put a 1 inch adapter on the torque wrench then put that in the open end of the gearwrench in the adapter. Then using a formula on line, convert that to what you have to ft-lb. Anyway It was worth it because I know I have a good product that will stand the test of time.



by:

This is the second one of these that I ordered from e trailer. The first one I got at the same time as the fifth wheel hitch. I install on my 2015 Silverado 2500HD. I traded that Silverado for a 2018 Silverado 3500 Z71. Kept the hitch had to leave the rails. Great product and not bad to install. Took about 2 hours. If I trade again, I will get third.



by:

Box was delivered with a little damage and the contents of the hardware bag was loose in the box. After going through the parts list and realizing I was missing 1 block, we contacted etrailer and they shipped the replacement part immediately, we got it within 3 or 4 days. Install was a breeze after watching the video and fishing the bolts and blocks in the frame. Only took a couple hours total.



by:

Very disappointed with the quality of parts I received from etrailer. I got parts for my 2015 GMC Sierra 2500 they look like they came out of the scratch and dent section. Like I understand that the item is heavy and it’s hard for it to stay prefect in shipping but for the amount paint missing and how beat up the parts are for [XXXX] dollars shocks me. I bought a new with wheel not a used one. This is a few photos of the many more I have hope this helps with your experience.

Installation of this product was easy, instructions were easy to follow. Rail kit works as it’s designed. Great Kit.

It been working great, have not any issues. This product was easy to install, pretty much straight forward instructions!



by:

This is a great product, but the install time estimates are way off. I have been a mechanic in my own shop for 19 years and I didn’t remove the rear wheels or the spare tire (because) it wasn’t necessary on my truck. I have a lift in my shop and it still took me 6 hours to install it! Trying to hold the spacers while trying to get the nuts installed on the 8 outer through the bed bolts was ridiculous! Terrible place to get to, lots of bad words! I’m thinking that buying the custom kit versus the universal was a bad idea, I have installed both and it was no quicker with this kit and it was almost a hundred dollars higher. My install was on a 2013 2500hd.



by:

If you do this yourself, definitely remove the wheel well liners and remove 3 of the 4 bolts holding the heat shield with one loosened to move it out of the way. Top front four nuts are the hardest to get started from under the truck. Start to finish 3 hours. Saved myself $500 for install

The kit should not have been missing hardware. I will have our Customer Service team reach out to you.



by:

Received the product yesterday and began my install. Spent a few minutes looking the directions over, which are pretty good to me at least. Took about 40 minutes due to the fish holes on the frame being difficult but over all a good product. I didn't think to get any pictures.



by:

Easy install, no complaints.

2017 Chevrolet Silverado 2500

Bought this rail setup over others because of price and that the profile is smaller than other models out there. Rails only stand 1-1/8" tall. I installed on a 2017 silverado 2500hd with an 8' box. I thought going in this would be an easy installation, but I was wrong, I feel like I had an easier time with the universal rails on my previous pickup. The shape of the brackets that bolt up to the frame make it so you can't get a wrench at the nuts anywhere but the inner side of the frame rails. The rear rail wasn't too bad to torque hardware, but the front rail hardware was a real pain to torque. Be sure to lower the spare tire. The driver side has the gas tank in the way, the passenger side has the heat shield. I found it a little easier when I removed the 1 bolt on the top of the frame holding the heat shield down, it made it so I could reach both hands up there to get the washer and nut on. Would highly recommend having a 3/4" crows foot socket to tighten the nuts that secure the rails down. I was not able to get a socket on them at all (love how the install video shows torquing the easiest nuts). I also had trouble bolting the brackets to the frame with the existing threaded holes (no fault of the manufacturer, the threads were just gunked up). The bolts that secure them are M16 (install video says 14), may want to have a tap that size on standby incase those threads are gunked up. I wish I would have spent the extra money on the Reese outboard rails (didn't because of the extra money and the large profile of the rails).

  • Reese Base Rail Installation Kit For A 2019 Chevy Silverado 2500
    With Reese's recent buyout (2023) some of their parts are bit hard to come by during the transition, with rail kits being one of the affected items. We do still have the Reese Universal Base Rails and Installation Kit # RP30035 in stock, but these are universal fit brackets which require quite a bit of drilling into the frame.

Because drilling through the frame will be required, you might seriously consider a custom install kit that uses existing holes in the frame like # C16411-204.

  • Can Fifth Wheel Install Kit From 2006 Chevy Silverado 2500HD Be Reused on a 2015 Silverado
    The fifth wheel hitch installation kit used on your 2006 Silverado isn't compatible with your 2015 Silverado, I'm sorry to say. This is because of the differences in the truck frame that occurred in the 2007 model year. Also, the hardware used to install the fifth wheel hitch in your 2006 Silverado is meant for a one time use only. It isn't meant to be reused. If your 2015 Silverado is a 2500 model, you'll need the # C16411-204 install kit. If you have a 1500 model, use the Curt # C16400-204...

  • 5th Wheel Install Kit and Slider Hitch Recommendation for 2015 GMC Sierra Duramax Diesel Short Box
    A fixed 5th wheel hitch cannot be used in your 2015 GMC Sierra Duramax diesel with 6.5-ft box. Short bed trucks like yours must use a sliding 5th wheel hitch in order to have enough clearance for tight turns. In terms of an installation kit I recommend a custom type since this will reduce overall install time and eliminate the need to drill into the truck's frame for the under-bed brackets. These will mount to existing holes in the frame. I suggest the Curt # C16411-204. For a sliding...

  • Will Curt A16 5th Wheel Hitch Sit Below Truck Rails on 2012 GMC Sierra 2500HD
    The Curt A16 5th Wheel Trailer Hitch # C16621 you referenced in your question will work with your 2012 GMC Sierra. The height of this 5th Wheel Hitch can range between 17-1/2 inches to 21-1/2 inches. I did some research and found that the depth of the truck bed on your 2012 GMC Sierra is 21 inches. To be sure the hitch will fit under your Tonneau Cover when it is closed, you can measure from your truck bed floor to the underside of the Tonneau Cover. As long as this provides at least 22...

  • Which Curt 5th Wheel Hitches are Not Compatible with a Sidewinder Pin Box?
    The Curt Q-series and A-series 5th wheel hitches are the only Curt hitches not compatible with a Sidewinder pin box. Instead of these models, you can use something like the Curt E16 5th Wheel Trailer Hitch - Slide Bar Jaw - 16,000 lbs # C16115. If you have the prep package then you'll also need Adapter rails # C47BR. If you don't have prep package then you'll instead need Rail Kit # C16411-204. To swap out your standard pin box with a rotating/sidewinder pin box you will need to know the...

  • Fifth Wheel and Rail Kit Recommend for 2016 Chevy 3500HD Towing Trailer with Max Turn Nose
    Normally for short bed trucks a slider hitch is needed to allow you to make tight turns, but since you have a trailer that has a narrow nose it would not be necessary. The Curt A20 hitch part # C16140 is a great hitch that would work well for you. This is the stationary hitch. For a rail kit you would want to go with a custom fit kit like the part # C16411-204 which is custom fit for your 2016 Chevy Silverado 3500. Custom kits limit the amount of drilling needed for install and cut the...

  • 5TH Wheel Bed Rails and In Bed Wiring For a 2017 GMC Sierra 2500HD
    If you are looking for the industry standard rails the Curt # C16411-204 includes the above bed rails and below bed mounting brackets. If you prefer a system closer to the factory install for a cleaner bed the Reese # RP30158-68 provides you with the 4 outer puck holes for using a 5th wheel hitch as well as the center gooseneck hole. The 4 outer holes are the same dimensions as that used on the Ford Puck system so you can use either the Fixed # BWRVK3300 or Slider # BWRVK3370 5th wheel...

  • Is Demco 16K Hijacker Ultra Slide 5th Wheel Hitch Compatible with Curt Mounting Rails
    The Demco Hijacker Premier Series Ultra Slide 5th Wheel Trailer Hitch like # DM6076P-UL-16K is compatible with industry standard fifth wheel rails such as those manufactured by Draw-Tite, Valley, Demco, Curt, Hidden Hitch, Reese and others, so the hitch will work perfectly with the Curt Mounting Bracket/Bed rail kit. If you have a 2016 GMC Sierra 2500, you'll want to use the # C16411-204 bracket/rail kit, as the bracket kit you'd looked at only fits the 1999-2010 Sierra 2500 models.
