This heavy-duty hitch is rated for 20,000 lbs gross towing weight and 5,000 lbs tongue weight, giving you solid muscle for hauling large fifth wheels. The sturdy steel construction and carbide powder coat finish stand up to long miles and rough roads. It’s a serious setup for anyone who wants a hitch that feels steady and secure every time you hook up.
The interlocking two-piece jaw wraps completely around the king pin to give you full 360-degree contact. That tight fit cuts down on rattle and movement compared to slide-bar models, so your trailer tracks smoothly and quietly behind you. It’s an easy way to make heavy towing feel more controlled and predictable mile after mile.
No second-guessing whether you’re locked in—just glance at the color indicator. Red means uncoupled, yellow means ready to couple, and green means you’re set for towing. The indicators are visible from the cab, so you can confirm everything without climbing into the bed. The handle also locks for security and resets itself after uncoupling, making it ready when you are.
The fully articulating torsion head self-aligns during coupling and helps absorb road shock for a quieter, more stable ride. It takes the edge off bumps and dips while still keeping the trailer steady behind the truck. The built-in zerk fittings make lubrication quick, so everything stays moving smoothly over time.
When it’s time to free up your truck bed, pull one pin to lift off the head—simple enough for one person to handle. The included rail adapter drops right into the puck receivers and secures with quarter-turn anchors, so setup or removal is fast. This design makes it practical to tow when needed and still have a clear bed whenever you want it.

What's up everybody It's AJ with etrailer.com. Today we're gonna checking out via Curt Adapter. Now it's for OEM puck systems in the bed. So it's gonna take the underbed puck system make it a overed puck system. That way you can attach your fifth wheel to this and use the one you have already. Let's check it out.
It's gonna be really good if you already have a fifth wheel that you used in roller truck, you wanna transfer it over to this system. It doesn't drop in the puck, or you just wanna upgrade to a different one that also works above bed. That's what this is gonna do. It's gonna convert the puck system to an above bed system and you just drop it in any of these tabs here right away. I wanna show you how easy it is to operate.
So I'm gonna pull the clip and the pen. This is a lever that's gonna turn this portion to let you lift it up and outta the pucks, and I gotta do it on all four sides, but it's really easy to do compared to some of the other adapters I've worked with. There was the Reese one that I've also used but it has the longer arms that pin here in the center and that can be kind of cumbersome to bring those all the way out here and out of the way to unlock it from the pucks. These are shorter handles, so you just push it out makes it far easier. It does clear everything right here.
You don't have to go for that long lever style. So now it's unlocked. I can just lift it up and out of the pucks. It's like our back one's stuck, so I gotta get that lever in the right spot, that easy to do. Now it's up and out of the pucks and we can take it out of the truck.
Installations just as easy. Make sure you got those levers in the correct spot. You see that this portion that goes down into the puck is lined up with it. You just lift it up. Drop it in. Now you might only get one or two of them in. Then you can come over here and adjust. Very easy to come down. I also like that there's plenty of room in between the bend and the bottom of the bar so you don't have to worry about smashing my hands when I'm dropping into place. Once it's lined up in place, you can pull the lever back over. It should go over there. That's gonna lock it in and then we'll put our pin and clip right there in the hole. The way it locks in those pucks is gonna help prevent chucking. I'm gonna try and shake it back and forth. You see it'll move a little bit, but not a whole lot. I'm really shaking the whole truck versus what's gonna move on the fifth wheel, the whole thing has a durable carbate black product oak finished. So if you leaving it in the back of the truck you don't have to worry about the elements bothering it at all. The tabs where you drop the fifth wheel legs in so this is gonna be what kind of fifth wheel spread will work with the adapter. It's gonna go from the furthest ones out. It's gonna be 29 inches center to center. The next one's in it's gonna be 21 inches center to center and then here's gonna be 10 inches center to center. So that should help you decide if your setup's gonna work with the adapter or not. Another thing to think about about is it is gonna add three inches to the bed so that means it's gonna bring your fifth wheel head up three more inches. Just keep that in mind when you're doing your setup. Overall, I really like this adapter. Like I said, it was easier to use than some of the other ones I have used. These quarter turn latches here and drop in the pucks. Make it really easy to get in into place or get it out of here when you want it out and it's gonna help convert that underbed system to an over bed system to using over bed fifth wheel. Well. I think that does it. Thanks for hanging out. I hope this helps..

The hitch adapter has worked out well. It’s great that Curt gives you an option to buying a new fifth wheel hitch when buying a new vehicle. Only pulled it out once. It’s an extra step removing it but no big deal.

Just got back from trip that I pulled 5th wheel 7800 miles. No problem with adapter rails. Only problem is top of hitch is about top of bed. I can used my bed cover with hitch mounted it truck bed.
Do you have a question about this 5th Wheel Hitch?
