The Curt CrossWing brings heavy-duty towing strength into a hitch you can actually lift by yourself. It’s rated for 20,000 lbs gross towing weight and 5,000 lbs vertical load, giving you the muscle for big 5th wheels without the bulk of traditional hitches. Premium steel construction and a reinforced head connection point keep it solid under load, while the carbide black powder coat helps resist corrosion. You get rugged performance that’s still easy to handle in and out of the bed.
Most 5th wheel hitches are a bear to remove, but this one changes that. Weighing only 60 lbs—about 65% lighter than most traditional models—the CrossWing’s two-piece design makes it simple to lift and store solo. Built-in grip points help you move it without awkward angles or risk of strain. When you’re not towing, clear your bed quickly and get back to using your truck for other tasks.
The CrossWing eliminates the guesswork of coupling. Instead of jaws around a king pin, it uses a wedge-shaped coupler that bolts directly to your trailer’s pin box. The large, open-faced head funnels the coupler into place so you can line it up clearly—even from your backup camera. That angled contact surface is visible as you back in, and the ergonomic handle locks everything down once seated. The result is faster hookups with less climbing in and out of the cab.
Towing feels more controlled thanks to Curt’s ShockDrop technology built into the hitch head. A polyurethane isolator absorbs jerking, jarring, and chucking before it transfers between truck and trailer. Combined with the CrossWing’s cushioned 360-degree articulation, it keeps motion dampened even on uneven ground. You’ll notice fewer bumps through the cab and less strain on your setup mile after mile.
With three height settings from 16-3/8" to 20-3/8", dialing in a level trailer setup is straightforward. The CrossWing also provides a built-in 5" offset for improved cab clearance during turns—especially helpful when maneuvering tight spaces. The included lube plate keeps king pin movement smooth inside the coupler so every turn feels controlled and steady.

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.
Ratings & Reviews
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.
Great product, well made and easy insta llation.
The adapter came packaged very well. The box looked ruff and I was concerned but when opened everything was good. Very easy installation.
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 a good price, fast delivery, easy to assemble & install in my truck. It matches with my Reese 16K 5th wheel hitch. I have not towed my camper with it yet but I do not foresee any problems with it.
Hmm, where to start? The hitch itself is a dream come true, it's stable, lightweight but strong, pulls my 16K fifth wheel smoothly and does everything I could ask for. The issues that I have with it are the Torque and Re-Torque requirements from Curt themselves, the Dry Lube usage, and the rust spots that have appeared on it.
Manual says, "Torque to 300 foot lbs." Do you realize how much that is? I had to buy a special wrench just to get one that went that high! Unfortunately you have to Re-Torque the hitch bolt pretty much all the time, I mean I realize it's actually the only thing holding the hitch head to the body.... But sheesh!
The other thing the manual says is to apply Dry Lubricant to the head prior to usage . Dry Lubricant makes a heck of a mess, and when it dries it's white! Makes it look like a Seagull has been using the hitch as a nesting spot.
Finally, have had this hitch since February 2025, using it since April on about four trips and I'm already getting rust areas around the safety latch/pin area and the hitch saddle itself. The saddle rust is surface and not a big deal, (that thing is never gonna rust through no matter how many decades of use). The safety latch/pin is a bit of an "I'll keep an eye on that" concern.
In summary, this hitch is perfect for us. I used to have the big grey monster and just couldn't lift it out anymore. The Curt weighs about 60 pounds and it's so easy to remove and install in seconds versus what used to take my wife and I an hour or so and lots of pain meds after. Like I said, the hitch is rock solid, easy to hookup to and easy to disengage when we arrive at a campsite. It is my pleasure to be able to endorse this hitch and give it my highest recommendation.
It is great thanks to etrailer for the help and I want to send a special thank you to Melissa for her help in selecting the right item for my truck
With new trucks prepped for fifth wheel and goose neck hitch mounts, this made it easy for me to use my old hitch in my new truck. It did add about 1 1/2” to the height of the hitch so I had to move my trailer hitch so the trailer runs level.
The CrossWing pulls great the issues are hooking up and unhooking. When you lift it off the hitch it isn’t smooth at all. When you hook it up it kind of falls in very hard. This isn’t a problem but the angle makes it tough.
This adapter worked perfectly for my 2025 Sierra 3500 puck system. It went together in about 15 minutes and was a perfect fit with my Reese hitch. Also, Paul at Etrailer was great to work with and he made sure I ordered the right part.
Easy to order, etrailer rep answered all of me questions, prompt delivery, very easy to assemble and install in truck. A great purchase.
This product is great. It was well packaged and very easy to install. I have a Pull Rite super glide hitch that fit 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.
Fits good works good fast shipping. Weight rated for much more than my hitch or truck needs to be latched onto
The Tech (Mike) that helped me identify the product I needed was very good to work with and communicated well. The person (Amy) who took my also was very good to work with and communicated well. The product arrived timely on the day it was committed for. The product was packaged well and did not have a damage, the installation directions were clear so installation was very smooth. The product is well made, heavy duty and fit as it should. I highly recommend etrailer and Curt products for any trailer needs.
This rail adapter work like i wanted it to. Saved us from having to purchase a New 5th hitch
Install was easy but you need a 2lb hammer help with the Install, I really liked that it raised my 5th wheel higher in my truck bed
I traded my Curt 16k slider hitch for this new crosswing
It definitely moved my trailer back 5 inches and I do not see the need for the slide hitch I rarely used.
It is lightweight and easy to manage by yourself ( my old one was just too heavy )
The new hitch has nearly eliminated all of the chucking and bucking.

One later and Still love it, I switched trucks to one that has a puck system, but bought an adapter plate cause I really like the hitch. The only drawback is leaving the adapter on the camper. If you have to move it with something else you can always take the two bolts off and remove it.
I have my pickup bed back! I had a “removable” slider hitch that was heavy and cumbersome enough that I left it in the truck. I replaced it with the Crosswing and I now have a removable hitch. The way the hitch mounts and the curve of the trailer mean I don’t need a slider hitch anymore. Good riddance!
The OE Puck Adapter 25K was easy to install. I put a little grease on the parts (6 and 5 on the instructions) - thought it would make it easier to rotate the locking handles into place. I have a "long handle" torque wrench so torquing the carriage bolt nuts to 125 ft lbs was no problem. I installed a Husky 16K S fifth wheel hitch installation onto the adapter. I still need to check the fifth wheel and truck bed clearance and adjust the height of the hitch as needed.
When I first purchased this hitch I was skeptical. Once I installed it, I was surprised about the weight and the easiness of putting it in and out of my truck. Since last year, I have towed my fifth wheel on 4 different occasions and am very impressed on how easy it is to hook up and how well it tows. The last time we went camping, I noticed another camper that had a bigger fifth wheel than I have and he had a Crosswing as well. I highly recommend this hitch.
Easy to install. Less than an hour. Curt Q20 slipped right in and it is still below the bed top. Others talk about a height problem. I had airbags on my f250 that i would inflate to bring UP my back end. I dont think this is an issue.
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.
Arrived on time and it was in perfect condition. Easy to put together, you do need a torque wrench that goes up to 300 foot pounds. Hitching up is very easy. I did a test tow and it was a huge improvement over my old curt a16 for a smooth ride. Looking forward to my next long trip with my new crosswing hitch. Thanks etrailer

Your new Curt CrossWing looks great! We'd love to hear about your experience towing with it after it's been on its first long trip!
Adapter rails are heavy duty, easy to install and were a perfect fit for the puck system on my 2026 GMC. My Husky hitch fit perfectly into the rails. Our first trip towing with this setup went great!
Do you have a question about this 5th Wheel Hitch?

It is super nice how much easier it is to manage this one vs. other styles on the market. Really happy that this got rid of the chucking! We'd love a photo of the new set up if you feel like sending one in. I can add it to your original review :)
