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.

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!

Glad you like it, Richard! These are definitely a nicer option than having to buy a whole new hitch! And what did you need to use the hammer for? I'm usually a fan of any percussive maintenance and am definitely curious here.

While I used this with the PullRite hitch it worked very well. I have since sold the hitch as the adaptor to buy a a different hitch no longer needing this adaptor. Worked great.

Hey Paul. I'm glad that Jacob got you all hitched up. What kind of 5th wheel are you towing?

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 :)

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.

Wow, I don't think I have ever seen a 23 year old hitch, before! That's awesome the rails worked for you. I'm impressed! You really had no issue and didn't have to finagle it at all?

After a year of use, I have no complaints. It does its job just fine. I will also add for others in the market, my father and law has a 2025 Sierra 3500 that he upgraded to, and upgraded his standard 5th wheel hitch to a Andersen Ultimate for the factory puck system. I was able to compare side by side the puck style Andersen to the rail Andersenadapter I have. The height of the hitches are the exact same.
