Hello neighbors, it's Brad here at eTrailer and today, we're taking a look at the Curt Adaptor Rails for 5th Wheels. Now, this is gonna work for the OEM prep package that we have here on our 2023 Chevy Silverado 3500. The puck system or OEM prep package, as they call it that a lot of newer trucks are seeing are really nice because you can simply drop in a 5th Wheel, but, if you already have a 5th Wheel and it's not compatible, it's normally in a rail system. Well, you can pick up this adapter to make that fifth wheel head work. Now, these are standard rails as far as the industry goes so it's gonna work with most 5th Wheel heads. The only one that really has compatibility issues, is gonna be the BMW Sliding Companion and that's just because of the clearance as it slides.
But that really opens it up to whatever 5th Wheel you may have or be looking at and still be able to hook this up. Now, something to keep in mind, this is gonna add height to the overall height of your 5th Wheel while in the bed, about two and a half inches. So, just something to keep in mind when adjusting your 5th Wheel and checking your trailer to make sure that it lines up perfectly. Now, while we have this on a Silverado it's also gonna work with GMC trucks. So, your Sierras are gonna work perfect as well, but also it has the adjustability to be able to work with the Ford ones, which you sit a little bit wider.
So, if you ever plan on getting a different truck and you still want to keep your same 5th Wheel you can adapt this and drop it into those OEM prep packages. (metal scraping) The handles just lock this into the puck system pretty easily. So, these will just unlock by sliding these out. (metal clanking) (boot thumping) And the great part too is there is some adjustability. So, not all prep packages fit exactly the same little bit of tolerance differences, but with our castle nut and cotter pin system here, we're able to actually adjust it to where you have that perfect tolerance.
Now, the black powder coat finish is gonna be nice, especially if you plan on leaving this in the bed especially uncovered, because that will hold up long term. Keep this from corroding or rusting at least give it a fighting chance for that. Now, this is a pretty heavy-duty kit rated at 25,000 pounds. So, while this is pretty heavy-duty, you also wanna make sure that you're checking the vehicle to make sure that it can handle the weight, and also you're only as good as your 5th Wheel. So, between all of those three components take the lowest of those numbers so you stay safe.
Now, this is pretty easy to assemble. It's pretty straightforward and can be done about 15 minutes with minimal hand tools. So, let's take a look at that so you can get yours installed. Gone ahead and laid out my parts and that way we can start assembling this. And it looks like, as far as tools go, it's gonna be pretty simple. A 3/4 inch socket, a 15/16 socket, a torque wrench, and a plier for our cotter pins. So we're gonna start here on the left side and I've just laid these out. So you'll see that one edge goes all the length of it. That's gonna be the inside of our rail. So, the way I have it laid out is the way that it's going to sit once we have it mounted up. We're going to slide over our spacer and you'll see that one side is gonna be thicker than the top side here, as I have it laid out. So, we'll slide, (metal clanking) we'll have the larger portion down here by the head of our bolt. This is going to fit right here. (metal clanking) We're gonna grab our side-specific handle, and you're gonna know that it's the proper one. You want the handle kind of to where this top portion faces or is at the same height here of our rail. And, there's this little notch that's our stop. So you should be able to move this, and this will kind of go in this center portion, that whole line up. Now, if it's not able to move, then you're gonna wanna swap that handle to the other one, and then we'll finish this up with a flat washer and our castle nut. I'm gonna go ahead and get this threaded down. And you don't wanna go too crazy here. I just hand did that. And so you still want to have some mobility here so you can kind of, loosen it up a little if you need to. (metal scraping) You wanna be able to slide this pretty easily and if you crank it down, you're gonna lose that. So, we do need to align it with the hole in the bolt. So find that sweet, happy medium of being able to move the handle, but still get your cotter pin through. So, I'm gonna go back one here And I'm happy with that. So, we'll go ahead and grab our cotter pin. (metal scraping) I may have to turn this here, but we'll feed this in and then pry out our ends, and that way it's gonna hold that in place. So, normally just a set of needle nose here will work well. Slide this down (hands tumbling) (metal clinking) and then as we bend both ends back, that should lock it in place. So with this one in place, we'll just go ahead and repeat for the other remainder ones again. Just making sure that our handles are able to actuate. Now, if you have your puck covers, you're gonna want to go ahead, take those out, and we're gonna drop this in. So with my handles kind of at a 90 here from our rail (metal clunking) we'll go ahead and get these tightened down (metal scraping) and then we'll align this hole here. And then we can put our linchpin in place, (metal clanking) and we'll just snap this in place. And then we'll go ahead and get our other side in as well. So now grab one of your rails, and you'll see the slots here for the 5th Wheel. You want that facing towards you. And then we'll line this up. (metal clunking) And on the GM trucks they're gonna be using the third and fifth hole. It should line up pretty well centered so you should know you have it in the right spot. We'll then take our carriage bolts and pass it through. (metal scraping) (metal chinking) Now in getting these in, if the tolerances are pretty tight and it's not wanting to pass through perfectly. What you can do is take that linchpin off. I loosen this side up and you're gonna want to get your outside ones in first. And that should align the middle ones a little bit better because if you do these two first, you might be a little bit off here. (metal clanging and scraping) Now once we have both of our rails in the front and back with all the carriage bolts passed through we'll go ahead and take our serrated flange nuts, and I'm gonna just hand tighten these on for now. (metal screw scraping) So, now we're gonna come back with our 3/4 inch socket and using the torque settings found in the instruction manual, I'm gonna torque all of these down properly. (socket crunching) If you need a torque wrench we have them available here at etrailer. You can generally go to an auto parts store and rent one for free. (socket crunching continues) Now, we'll just go ahead and repeat for the remainder of the hardware. So, you can see I have my Curt E16 5th Wheel that we just dropped into the rails, and I can go and grab a different 5th wheel and do all the same. All that's left to do is pin it in place through the rails and then we're ready to hit the road. And that was a look at the Curt Adapter Rails for OEM prep packages on a 2023 Chevy Silverado 3500.
Had to replace my vehicle while on vacation. 2020 puck system was different than the 2025 puck system so I had to order a new base. Ordered the new base on a Friday and it was delivered the following Monday. Jacob was extremely helpful throughout the whole process. Package while extremely heavy arrived intact. Bolted rails together. Specs very tight on the 4 pins that hold the base to the hitch. Needed a little coaxing to get it pinned. Definitely a two person job. Would use e-trailers again in the future. Thank you for your speedy service.
I needed to move my in-laws 5th wheel trailer and didn’t have a 5th wheel hitch for my 2022 puck system. I wasn’t sure the new adapter would work on a 23 year old DrawTite hitch, It worked perfectly !!
Assembly and setup was super easy and quick. Seems super stout. I was worried the added 2 1/2 inches of height added by this would require some adjustments to the pin box. However once hooking up my trailer, no adjustments were necessary. Trailer is almost spot on level, and I am still maintaining 6.5-7 inches of bed side clearance to the trailer.
Easy assembly, easy installation , fit perfect, works perfectly. I have only used the hitch once. I don't see any issues going forward with this hitch adapter. Highly recommend it and e-trailer .
Easy to assemble and install. Love that it snaps into the puck system in the truck bed and allows me to remove the entire hitch using an electric hoist, easily.
Purchased a 2024 Silverado 3500 set up for 5th wheel with the PUCK connections. My previous truck had ISR rails and the PullRite SuperGlide 5th wheel hitch. The Curt adaptor is the perfect solution to avoid buying a whole new hitch.
The package arrived in good condition and on time. Upon opening the box I was extremely surprised how well it was packed, each corner had a metal bracket, there was a piece of plywood on the bottom and top and foam separating the parts.
The install was fairly easy, read the instructions, Chevy is one way, Ford another. The PUCK locking mechanism make a nice tight connection with very little adjustment needed. The rails fit in nicely and the bolts went in well, torqued as required.
I have not yet attached the PullRite hitch but if it fit the Curt ISR rails on the previous truck it should fit this one. With the Chevy 2500 I had, between the squat and ISR rail setup the 5th wheel was slightly lower in the front. With this Chevy 3500 suspension and the adaptor being about 2" higher I expect the camper to be level or slightly higher in front which works.
Very nice adaptor if you have the need, better than changing out a perfectly good hitch.
Well the package arrived on time but the box was damaged severly. Not sure if all the parts was in the box. After reviewing the items along with the instruction being ripped, all parts was present.
Like some other posts, followed instructions to the letter and hitch would not drop into rails. Loosened all the rails bolts, mounted hitch, and re-torqued everything. Puck mounting brackets were just off square a bit and twisted the rails when first installed. Either square ‘em up or alter instructions so it goes in first time. Installed in a 2022 Silverado 2500 6’10” bed. Loved the plan, set the rails first time in a few minutes (instead of waiting in a shop for four hours while someone else did the boring and cutting and such). Hitch has been in two other trucks with conventional rails and always fit. Coulda been a five star, but I am familiar with Curt and feel sure they will get it right.
It was very easy to assemble and install. Maybe 10 minutes because I had to grab a wrench. It was also in question if it would work with other brands and in my case no problem working with my Reese hitch. It as able to email correspond and have my questions answered very quickly.
Well built. Using to adapt a Patriot 18k slider to Ford pucks. For this particular hitch, I did have to grind a small slot about 1/3 into the 2 front latching handles to clear a structural hitch component. Not Curt’s fault whatsoever.
Hello to all , I want to give a Big Thank You to Nick for his assistance in my 5th wheel hitch solution with my F-350 it has a overball style in it already....... problem was I already have a curt 5th wheel hitch that would'nt mount up to my truck So maybe a new hitch?? Nick listened to my problem and gave a solution with a Curt assembly that works for my application that work for my F-350 and the hitch I have already.... Installed it no problems and it worked out great for me so far..... Thx again
This rail set is awesome. It was packaged extremely well, went together perfectly and easily. This fit the pucks first time and only required minor adjustments to the castle nuts to snug the fit to the puck. Tip for others, When I put this together I left all the bolts finger tight until it was fitted to the pucks, torqued the bolts to specification and adjusted the castle nuts to snug. Easy. Curt Crosswing hitch dropped right in pins fit with ease.
Really wanted to give this 5 stars but it appears they didn’t try it with a hitch like mine. The flanges on the cross supports do not allow my hitch to seat down onto the support tubes. Thus the hitch holes will not line up with the tube holes and the pins cannot be inserted. I fixed it by taking a sledge hammer to the ears on my hitch until the holes aligned. I shouldn’t need to do that to something this expensive.
This rail adapter work like i wanted it to. Saved us from having to purchase a New 5th hitch
The adapter itself appears to be solidly built and if it were compatible with my B&W Companion Slider 5th Wheel Hitch I'd probably be giving it a 5 star review. The issue is I purchased a 2019 GMC Sierra 2500 HD Crew Cab Denali back in'19 and with the standard short bed truck I wanted a "Slider" style hitch For pulling our 38'Grand Design Solitude. I loved everything about the truck/hitch/trailer set up. With the new technology of additional torque, higher weight towing capability along with the camera array that makes your coach practically invisible. So, you guessed it, I purchased the 2025 exact truck and trim model but what I didn't know was the GM decided to change the truck bed OEM Puck system in 2020 to accommodate, well I don't know why they changed it but the pattern and dimensions were now no bueno as far as towing my rig without some kind of changes being to my system which meant a minimum of around $XXX for an adapter for the base of the hitch along with some additional hardware or $XXX+ for a new complete hitch. After doing my due diligence of researching the various options and reviews I opted to go with the Curt Base Rail Adapter, Model #16027 which is compatible with my '25 GMC/GM/Ford OEM Puck system (verified through numerous reviews as well as eTrailer's sales rep when I placed the order), or so I was lead to believe, that it would be perfect for my truck and hitch mounting problem. However once I installed it there were numerous issues. The keyway on the legs on my hitch were too big to fit in the puck holes (1" thick keyway vs. the 1/2" slot on the adapter rails), the slots for the legs were still off slightly and the handles on the hitch base would be off by 90 degrees when in the locked position.
solutions So I have now reached out to B&W for their suggested remedy to my issues. I'm expecting it to be one of the higher dollar resolutions i.e.- new base with the correct OEM puck orientation (around $XXX) or a new complete hitch ($XXX+). Hey, I only wanted to add a new truck to the equation... Sorry for the lengthy review but ask anyone that knows me, they'll tell you that's how I tend to roll. If you ask me what time it is , I'll tell you how to build a clock.
Good service and fast shipping, very good quality and no problems to install, thank you.
Easy to assemble only 8 bolts required. Puck attachments come pre installed.
Have not gotten to tow yet but everything went together fairly easy. One major disappointment was the shipping and the packages were dumped in my driveway. Also it was not clear if I should use the spacers on this while installing the A16 hitch. I tried to get them to fit but could not get the pins to fit so I removed the spacers.
Received my order went to put it together and the pin holes on the rails don’t lineup with the GMC three and five on both sides. Try to get a hold of my rep Cel but apparently she’s gone until after May 20 of 2025 called and left her a message so then I was transferred to another representative Nicole talk to her asked for videos pictures that she would get back to me called twice left two messages sent videos at this point I just wanted an RMA because I had a trip planned for this weekend and now I can’t even do that cause I won’t be able to haul my fifth wheel trailer so if somebody can just get back to me, I would appreciate it so I can return this and either get my money back, which is probably what I wanna do at this point since I’m having a hard time getting in communication with the people that are supposed to help me
Easy install, great fit. Haven't pulled the 5th wheel yet....but if it goes well,I will be completely satisfied. Easy ordering, and very quick shipping. Love your company
After purchasing a new truck, I needed an adapter for the Chevy puck system without buying the entire 5th wheel hitch, this fit the bill. Heavily built and easy to install. The only thing I would recommend is to use larger cotter pins because the ones that came with assembly would not engage the castle nuts.
Arrived on time. Well packaged and easy installation
Heavy duty, went together easily, torqued the bolts with the hitch in place to make sure the alignment was right.
Easy assembly. Adjusting handles took a little longer than expected, but once adjusted, they worked like a charm! It was a bit heavier than I expected. Highly recommend two people working with it. And once a 5th wheel is attached, definitely need at least two to move it out of the bed.
Ordering this product and installing it was simple. I couldn’t believe how easy it was to install and there are only 8 bolts to install. I put it off for a while because the weather was so bad and I was nervous what I was getting into. To my surprise it was simple great directions easy to follow. And the packaging I have never seen anything like it before. Thank you etrailer I won’t be ordering from anyone else for now on.
