Video Transcript for Curt Fifth Wheel Kit Installation - 2018 Ram 2500

Speaker 1: Today on our 2018 Ram 2500 we're gonna be taking a look at and showing you how to install the Curt custom fifth wheel installation kit for Ram trucks in a carbide finish, part number is C16427-204. Now it's also available in a black gloss finish, part number C16427-104.Here's what our fifth wheel installation kit looks like once we have it installed and this is gonna allow us to tow a fifth wheel trailer safely down the road. The rails in the bed have several mounting points because they're gonna accept most industry standard fifth wheel bases or sliders. Whenever we're not towing with our fifth wheel and we pull the head and the base out our rails are only gonna take up about an inch above the floor of our bed that way we still have plenty of room to load it up with whatever we may need.This is a custom installation kit which is gonna cut down a lot on the install time. We're not gonna have to drill into the frame at all, it's gonna use existing weld nuts, but we are gonna have to drill several holes in the bed so we can attach the rails. Now the rails themselves have a nice powered coated finish to protect them and keep them looking nice and the carbide finish on these in particular is gonna match the Curt fifth wheel's exactly.Now that we've seen what our installation kit looks like and the rails in the bed let's show you how to get it installed.

To begin our installation I went ahead and lowered our spare tire and now we're gonna need to remove the exhaust shield here. We're gonna three bolts towards the back that are holding it in place as well as two more that are going on the cross support, we'll be using a 10 millimeter socket to pull those out. Once you have all the bolts removed you can go ahead and set it aside for right now.On the passengers side just forward of the axle we're gonna have two weld nuts in the side of our frame. We're gonna wanna grab our forward bracket, it's gonna be the larger of the two in the kit, and the two tabs are gonna be going towards the top with two oblong holes going towards the front of the truck. You're gonna line up the holes in the bracket and we're gonna take one of our shorter M12 bolts and we're gonna slide a conical tooth washer on, making sure that the teeth are gonna face the bracket, and we're gonna loosely thread the bolt into the frame.Then on the backside you'll notice that there's a small gap here in between the frame and our bracket so we're gonna take one of our square spacers blocks and we're gonna slide it behind the bracket in between the frame and then we're gonna have a longer M12 bolt and another conical tooth washer and we'll get that in place.

Now for right now you just want to get them in there hand tight and make sure the bracket doesn't fall down. Once you get it nice and snug we're gonna push the bracket all the way back until it bottoms out and we're gonna push it up against the top of the bed as much as we can, making sure it's nice and square and then we're gonna repeat the same process on the drivers side.With our brackets in place, making sure that we have both of them shifted towards the rear all the way and nice and snug, we're gonna take a rather small drill bit and I'm gonna go to the very center of the hole and I'm gonna drill straight through going up into the bed, we're gonna repeat that for the other remaining holes on both brackets.Now we can move into the inside of the bed and we're gonna take our rail and we're gonna line it up with the holes that we drilled on each side. For our forward rail we're gonna line it up with the second hole from the outside, then we can mark our center attachment point. We're gonna be using the one towards the cab so we're gonna go ahead and take a paint marker and we're gonna mark that center attachment point right behind the rail. We can move our rail, drill out that hole, and enlarge the holes to the final size.

I'm gonna take a step bit and I'm gonna enlarge the hole to just a little bit over a half inch so our half inch bolts can fit through. It doesn't hurt to grab one of the bolts and test fit it before you go too big, maybe just a little bit more so I don't have to fight it going in. Now we'll repeat that for all the remaining holes.It's never a good idea to leave exposed metal on your vehicle, we're gonna take a little bit of spray paint and I'm gonna go over the holes that I just drilled to help prevent any kind of rust or corrosion from building up. We can take our rail, line it back over your enlarged holes and we can take our carriage bolts and we're gonna start dropping them through, they go down through the bed.Now any spot that the rail is sitting over a low spot on the bed, there's that corrugation where you've got a high spot and it dips down, you're gonna want take one of these U shaped spacer blocks and lift up the rail and slide it in so that the bolt has a little bit of support and it won't crush the corrugation. You want to go around and check each one and see if it's on a low spot or not and if it is go ahead and slide in one of those spacer block.

Now all our carriage bolts came through our brackets, you're gonna take a square spacer block, slide it over the bolts, then we're gonna take a flange nut and secure it. Now you want to be careful not to push the bolts back up into the bed, you want to make sure it's fully seated so you have enough room for that nut to grab. Just push the bracket up and we can attach the nut.If you're having a little bit of trouble getting everything on it could be because the carriage bolt isn't fully seated so a trick to get it seated all the way is if you just take a nut and you drive the nut on it'll suck that carriage bolt in, giving you a little bit more room. Let's thread on the nut, grab a three quarter inch socket, drive it in, you can see that it draws the bolt down and we can loosen it up and insert the block. Now we have a little bit more room with the bolt sticking out so we can get the nut started and we'll repeat that for all the remaining fasteners.Now that we have our forward rail in place we can go ahead and grab our base or our slider and we're gonna use that to make the measurement for our rear brake. Now if you're using more than one base or more than one fifth wheel it's a good idea to go ahead and test fit those that way you know that everything's gonna fit in there nicely. We're just gonna lift up our rail and our base and slide it over so we can get it in the mounting tabs. Once you have it in you're gonna want to grab the rail itself and pull back towards the tailgate so we have a nice, secure fit and then we're gonna mark out all our holes.In the rear rail we're gonna be using the very inside for our holes and then one in the center we're gonna be using the one towards the tailgate. Now again just gonna take a small drill bit and I'm gonna drill right in the center of the hole all the way through the bed and we'll repeat that for all of our remaining holes. Now for our forward holes on our rear rail we're gonna have to get an extra long drill bit because we're gonna have to go through the bed and then through the hat channel to make it all the way through.I drilled my one-eighth hole and I'm gonna come back with a larger, longer drill bit so I can go all the way through the hat channel and we're gonna do that for both forward holes. Then we're gonna grab our long 9-16ths drill bit and we're gonna enlarge all the holes to a 9-16ths and that long drill bit's gonna help out that way we can go all the way through the hat channel, making it a lot easier. We'll repeat that for all of our remaining holes. With all the holes drilled I'm gonna go ahead and slide my rail back into position.Here's the hole that we drilled on the drivers side through the hat channel, now the reason why we drilled the hole all the way through is that bolt's gonna come all the way to the bottom but we're gonna need to have this spacer block inside our hat channel so we don't crush it when we tighten everything down. To make things easier on ourselves we're gonna grab a step bit and we're gonna drill that out to a seven-eighths inch that way we can slide the support bracket inside the hat channel. You may want to periodically stop and check and only drill out once you can get this in place. Once we can get our spacer in place we're gonna come back and put a little bit more spray paint to cover up the bare metal.Now we can see that our spacer block is gonna be bigger than the hat channel itself. I'm just gonna put a mark where it's gonna be about even and then I have to trim our spacer block down. Now you can use a grinder, a cut off wheel, or anything you have to trim that off but we are gonna have to trim both of them so they can fit inside the hat channel. Now on the passengers side we are gonna have this exhaust bracket here so we're not gonna be able to get a step bit in far enough where at the angle that we can get our spacer block in. Because of that that's why we only need to drill the bottom out so that the hardware can come through so we're gonna leave the outside of the frame and meet up with our hat channel and feed our spacer block in from the side.I'm gonna take a magnet and I'm gonna push my spacer block into place and once I get it fairly close I'm gonna move back underneath and make sure that it's line up and I'll take a screwdriver to help me line it up. You can see my spacer block is right here, put a screwdriver in there just to hold it in place so I can remove the magnet. Now we can move back up top and start dropping all of our hardware through. To help you out you might want to use a screwdriver going through the rail and through the bed to hold that spacer in place. Now since it's in a weird position and that exhaust bracket is in the way we're gonna take one of our long hex bolts, followed by a flat washer, and very carefully you want to remove the screwdriver, make sure we don't knock the spacer over, and then we're gonna feed our bolt through, the screwdriver will help you get it lined up, make sure you go all the way through that spacer block and drop it all the way though.Four our three very rear mounting points we're just gonna take our half inch carriage bolts and drop them down just like we did with the forward rail. Then finally we're gonna have one long carriage bolt and we're gonna drop through the drivers side forward mounting point and then go back underneath, put our spacer in this inside, and get our hardware in place. Don't forget if it's on a low spot you want to grab another one of these U spacers and slide it under so that it won't crush the bed. You may need to kind of lift up a little bit just to get that spacer in place, make sure it goes all the way around the bolt. We'll go around and make sure that we get this in place and any of the low spots on the bed.Over here on the drivers side frame rail you just need a flathead screwdriver and we're gonna pop that connector holding the wiring harness down to the frame, you want to move it out of the way. We can take our tube spacer and we're gonna slide it around the bolt going to the hat channel and push it into the hat channel and just kind of push it to the side so that the bolt will keep it in place. Just like the forward rail we're gonna grab our bracket, since this is the drivers side this is gonna be the larger of the two brackets, gonna have to just kind of move the wiring harness around a little bit so we can get our bracket in place.Once you get your bracket in place we're gonna loosely secure our bracket again with those M14 bolts and the conical tooth washers, making sure that they face towards the frame and the bracket. Just gonna loosely put them in that way we don't have to worry about the bracket falling down. Just like the forward bracket I'm gonna take our spacer block and a half inch flange nut and loosely secure it to our bracket. We'll repeat that same process on the other side.Because of the position of where this exhaust bracket is it holds it in place and where our bolt goes through the hat channel we're not gonna be able to easily to get this bolt and plate in place. We're gonna grab an extra set of hands and have them pull the bolt up and we're gonna get everything in place sneaking in through the side here I'm gonna have them thread it in from the top.We're gonna go ahead and snug down all of our hardware and per the instructions they'll want us to snug and tighten down the bolts that are attaching the rails to the bed first so using a three quarter inch socket we're gonna snug up all the vertical bolts first. With all the brackets tightened to the rails we're now gonna tighten the brackets to the frame. We'll be using a 19 millimeter socket and snug them all down. I'm gonna come back with a three quarter in socket and torque the rails to the specified amount in the instructions, we'll repeat that for any remaining hardware.Then we come back with our 19 millimeter socket and torque the brackets to the frame and we'll repeat that for any remaining frame bracket bolts. With our rails torqued down we can go ahead and reinstall the bolts that will hold our heat shield in place. Now all we have left to do is put our spare tire back and that'll finish up our installation.That'll finish up your look at the Curt custom fifth wheel installation kit for Ram trucks, part number C16427-204 on our 2018 Ram 2500.

Before even starting the install I was sure to read the directions a couple of times to make sure this was something I wanted to attempt on my own. I hadn't installed a hitch before but had assumed since it was a custom kit it wouldn't be too difficult. The directions stated that the total install time for the diy'er was 180 mins. I read through and took note of all the tools I was going to need. What I would have REALLY appreciated was a "tools required" list at the top of the instructions. I thought I had all the tools needed but at the very end when you get to the rear rail you need a 7/8" bit for the bottom of the bed support. I advise you have one at the ready. I had to hone it out with my 9/16 which was a giant pain. Everything else went really smooth. On my particular application I had a real hard time torquing the front right bed bolt on the rear rail to spec (110ft-lbs) as the mount for a cross-bar makes it nearly impossible to fit a torque wrench in. (I ended up having to use 3/8" drive extensions to go up inside the bucket and torquing it from the bottom. Total time:(including a couple of breaks, meltdowns, and a bunch of swearing and a 2yr old hiding dad's parts) 180 mins. Touche' Curt Mfg., touche'... Experience level of installer: None This is something that the average person can do. Make sure to watch all the helpful videos here on etrailer.com, read through the directions before starting, and make sure you have all the necessary tools to help ensure your installation goes as smooth as possible. 121928

2015 Dodge Ram Pickup

Brackets and rails were of high quality and were a perfect fit on my 2015 Dodge Ram 2500 HD, using the factory frame 'jig' holes for attachment . INSTALLATION NOTES: I looked up eTrailer's installation Video on the Dodge-specific custom brackets (in this case on a 2014 Dodge Ram 2500 HD). It was invaluable! It stated the task would take 1 and 1/2 hours for an expert; 3 to 4 hours for a novice. I am NOT an expert but have torn down and rebuilt an engine, replaced clutches and transmissions, and done brake jobs on my vehicles. Being admittedly slow because I want to be thorough (I wanted NO mistakes in drilling the holes needed into my new truck's bed), the task took about 3 days. THE ISSUE: Though the under-bed brackets were perfectly made, there are two differences between the 2014 Dodge shown in the video (which I suspect was Gas engine equipped) and my 2015 Dodge 2500 (Cummings Diesel). - CLEARANCE BETWEEN DIESEL FUEL TANK AND FRAME appeared to be MUCH less on my 2015 Dodge than the fuel tank on the 2014 Dodge (Gas?). The front left (in front of rear axle) frame bracket installation was WAY more difficult than in the video due to this clearance issue. A standard Torque wrench head with socket could not be fitted over the forward-most bolt due to this clearance issue between the Diesel fuel tank and the frame. I finally broke down and used a 'breaker' bar/socket combo and a piece of pipe to get that particular bolt tightened within a reasonable range of the proper torque. - The rear axle suspension in the 2014 Dodge installation in the video was different than my 2015 truck. A significant mounting bracket for the new torsion bar was attached to the right-rear portion of the axle. I was adamantly against temporarily removing it (not even sure if I could have -- I THINK it was welded in place). Again clearance issues made installation of the right rear bracket quite a challenge for me. Still I applaud eTrailer for making a high-quality kit that fits the bill! 310005

Haven't had a chance to use the hitch yet but I got it installed without too much trouble. It took about 4 hours to install, the frame mounting brackets and rails, at a leisurely pace. The unit seems to be very sturdy and it is certainly built heavy. I'm looking forward to testing it out soon. 652239

The only reason I am not giving a 5 star is I get a lot of noise out of the unit I bought. I had the Ram dealer install my unit so I would hope it’s installed properly however I get a noise when towing my fifth wheel that sounds like the bed is twisting and moving. I had the dealer lift the truck up and I personally checked to make sure the sleeves that go in the bed supports were properly installed. After everything was checked for tightness and proper installation I still get the noise. This is my first fifth wheel that was not factory installed so perhaps this noise is common. This is my only complaint. This has otherwise been a great product. 862002

On time delivery as expected, boxes slightly crushed, all hardware was still intact and in the boxes. Assembly simple, the video should have covered each point of the frame attachments underneath the vehicle and removing the wheel well covers makes it easier to install the channel spacers so drilling a larger hole than the spacer is not needed. 828754

  • Correct Curt 5th Wheel Brackets for a 2019 Ram 2500
    The correct Curt Custom Fifth Wheel Installation Kit for a 2019 Ram 2500 is part # C16427-204 which consist of the Curt Universal Fifth Wheel Base Rails part # C16204 and the Curt Custom 5th Wheel Bracket Kit part # C16427. This option is a bolt-on fit, no drilling into the frame required. If you don't already have a fifth wheel hitch, the Curt A20 5th Wheel Trailer Hitch part # C16140 or part # C16541 is what I recommend because of the interlocking jaw system which reduces chucking/jarring....

  • Does Rear Rail of Curt 5th Wheel Rail Kit for 2014 Ram 2500 Only Bolt Through Truck Bed
    I attached a picture that I took from the install instructions for the Curt fifth wheel rail kit part # C16427-204 and that specific bolt does only attach to the truck bed. I also attached an install video for this as well. It seems odd, but this is how Curt designed the kit and tested it to determine it was safe.

  • Does 5th Wheel Trailer Hitch Bracket Kit Fit on 2015 Ram 2500 with Spray in Bed Liner
    First of all, yes part # C16427-204 is the correct bracket kit for your 2015 Ram 2500 and the rails as well as the hardware is all included. It can be installed with a spray in bed liner, I've linked a video of a 2017 Ram we did with a bed liner for you. With that being said we've got some reviews from customers who have said the bolts are sometimes more difficult to fit and properly torqued because of the bed liner so don't be surprised if it's not as easy as your last truck.

    The final authority on a vehicle's towing capacity will be in the owners manual. To get as specific of a towing capacity as you can possibly get you will need to get the Gross Combined Vehicle Weight Rating which means the max weight the vehicle can tow including the weight of the vehicle, it's cargo and the weight of the trailer loaded. You will then need to subtract the weight of the tow vehicle when it is loaded and ready to tow and the amount of capacity left over will be how heavy...

    A short bed truck by itself can pose a challenge for 5th wheel towing due to the limited front-to-back clearance between the truck cab and the trailer's overhang. When we add the Rambox feature we also add another complication: reduced side-to-side clearance. Hitch makers like Reese, Curt and B&W discourage use of 5th wheels in such trucks; that said, there are those that have satisfactorily installed 5th wheels anyway. The best solution for the turning clearance problem in such trucks...

  • Towing Capacity of 2015 Ram 2500 with 6.4 liter Hemi and 4.10 Gear Ratio
    I looked up the towing capacity of your 2015 Ram 2500 and based on the info you listed with exception of having an 8,000 lb rear axle I was able to determine that your overall towing capacity would be 15,590 lb. Everything I found your vehicle states that the rear axle was 6,000 lb capacity. Since vehicle towing capacities aren't hinged entirely on axle capacity I'd be shocked to see if the total trailer capacity would be different. The only place who can confirm that would be a Ram dealer...

  • Can a Fifth Wheel Hitch be Used With Weather Guard Toolbox on 2016 Ram 2500?
    According to my research the Weather Guard 126-5-02 is 20-1/4" from the back of your 2016 Ram 2500's cab to the front of the toolbox though please be sure to measure to verify this. Then, to figure out if you will have the clearance, what you can do is use the attached diagram of the Curt Custom Fifth Wheel Installation Kit for Ram Truck # C16427-204. You will notice with an 8 foot bed on a Dodge Ram 2500 there will be a dimension of 55-7/8" from the front rail (closest to the cab)...

  • What is Weight Rating of Curt Fifth Wheel Rail Kits
    Fifth wheel rails like the Curt rail kit part # C16427-204 you referenced basically are rated as highly as the fifth wheel hitch that's installed in them. So if you used a 25k Curt A25 # C16180 you'd have an overall capacity of 25,000 lbs or if you went with an A20 part # C16140 you'd have a 20k capacity.

  • Will Curt 5th Wheel Trailer Hitch Installation Kit Fit a 2016 Ram 2500 with Factory Air Suspension
    I did some checking at Curt 5th wheel trailer hitch installation kit # C16427-204 does indeed fit the 2016 Ram 2500 with the factory air suspension system.

The Curt hitches are a great value and both of these models have cushioned heads for improved ride...

  • Fifth Wheel Recommendation for a 2014 Ram 2500 with Rambox
    I have a solution for your 5th wheel towing needs on your 2014 Dodge Ram 2500 with a Rambox. I recommend to start with a fixed fifth wheel like the Curt # C16115 and the Installation Rails that go with this system are # C16427-204 they are custom fit for your truck. This will give us a rigid base to then attach a sidewinder to. You will need a sidewinder because the issue is the bed is more narrow on models that have the Rambox feature. This allows the trailer pivot point to be...

  • Do 5th Wheel Installation Brackets Require Specific Set of Rails for 2015 Ram 2500
    A fifth wheel installation kit does require a specific set of base rails from the same manufacturer. What that means is if you aren't sure the base rails you currently have then you will need to get an all-new set of both brackets and rails. So for your 2015 Ram 2500 I recommend going with a custom-mounted kit that does not require any drilling. That is not only good for your truck but also saves literal hours when doing the installation. The kits that fit your '15 Ram 2500 are: -...

  • What Is Needed to be Able to Tow a Fifth Wheel Trailer with a Ram Truck with a Ram Box
    The only way we are aware of that will allow a Ram truck with a Rambox to tow a fifth wheel trailer is if you replace the pin box of the trailer with a Sidewinder. This moves the pivot point up higher on the trailer so that the pin box would not end up hitting the sides of the truck bed rails/Ram box. Sidewinders are pin box specific so you will first need to know what pin box you have now in order to pick out the correct one. There should be a sticker or a stamping on the OEM pin...

  • 5th Wheel Trailer Hitch to Fit Under Roll & Lock Bed Cover on 2014 Ram 2500 Short Bed
    5th Wheel trailer hitches are height adjustable. You just need to find one that can be adjusted down low enough to fit under the cover on the bed of your 2014 Ram 2500 short bed. Pro Series Hitches # PS30094 and # PS30121 and Reese Hitch # RP30051 are good options since they are height adjustable from 13 to 17 inches. The lowest setting cannot be used since they are slider hitches for short bed trucks but that shouldn't matter with these hitches. You will just need the proper installation...
