The Curt A20 5th Wheel Hitch with S20 Slider is built from sturdy steel and rated for 20,000 lbs gross towing weight with a 5,000 lbs vertical load limit. It’s made for serious towing—heavy campers, toy haulers, and RVs that need a solid connection. The carbide powder coat finish holds up against wear and rust, while the interlocking jaw design and torsion head give you a ride that feels stable and secure mile after mile.
The interlocking two-piece jaw wraps completely around the king pin for 360-degree contact. That tight fit cuts down on rattle and movement so your trailer feels steady and quiet behind you. The color-coded three-point indicator system shows you at a glance whether you’re uncoupled (red), ready to couple (yellow), or locked in for towing (green). You can check it from the cab or from the side of the truck, giving instant confidence that everything’s connected the way it should be.
For slow-speed turns where clearance matters, the non-binding S20 slider gives you up to 12" of fore/aft travel. It automatically latches in both directions, so you can get the space you need between cab and trailer when maneuvering into campsites or parking lots. The quiet slider design keeps things stable while still letting the hitch move where it needs to during tight turns.
Installation is straightforward—just drop the base into your factory puck receivers and pin it into place using the included rail adapter. When it’s time to remove it, pull one pin and lift off the head for easier handling. Two built-in zerk fittings make lubrication simple, and the included plastic lube plate helps the king pin glide smoothly into position during hookup. With height adjustment from 17-1/2" to 21-1/2", you can dial in your setup for a level, secure tow every time.

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..

Great solution when moving to a truck with the puck system. This was cheaper than buying rails,brackets, and install costs, and when removed the bed is clean.
etrailer always makes it easy to order. Shipping was fast and surprisingly the shipping company didn’t damage the box to bad. Bitch fit perfectly without any complications. It is heavy yes but seems very durable.
Fits perfectly and easy install
Very nice rail set up that you can remove when not in use, works great with my Anderson Hitch that was set up for a rail set up on my new 2022 Ram 3500. Also has slots for the chain hooks.
Heavier than expected (95#) shipping weight. Which is a good thing. The description probably said that but I didn’t pay attention. The only warning I would give I’d that this with add 3.25” or so of height to your hitch. If you don’t have the adjustment in your set up you may want to look for something a little lower profile. I’m happy with the purchase and very happy with etrailer. Very fast shipping and good prices.
Very easy to install. Although it is a heavy unit and I ended up getting my son to help me put it in once I assembled it.
Took about 15 minutes to install. Heavy duty. Can't wait to pull with is
I have only had it installed, I have not towed with it yet that's why ony 4 Stars. Installation went very well and fast.
Works great, heavy duty as you would expect from Curt. Installed this on my new truck with a Curt R20 slider and Curt A20 hitch head. Installation was easy and eTrailer delivery time was great as usual.
Fits like a glove. From the time UPS dropped it off it took 45 minutes to have it installed in the truck and we were hooked up to go camping, which we did! Thanks to the team for getting it shipped asap! 2020 Ram 2500 with the factory puck system.
First, the is a very heavy duty hitch. I watch the etrailer videos and the installation was simple. No issues at all. Second, I order from Matt who was very helpful an knowledgeable on the product. He said it would be delivered in two days. I laughed but low and be hold it was delivered in two days and the packing was incredible. I Thank you Matt for all you assistance.
Not very happy with this product. With the hitch mounted to this rail, you could feel the play between the rail and the hitch every time I braked or accelerated I ended up selling it at a severe loss. It will get you out of a bind, but if you are looking at this for long term, just buy the hitch made for the puck system.
Easy to install and works perfectly!
Easy to install, took me about 45 minutes. Be sure to put your hitch in place before tightening the 8 bolts. It does sit pretty high so will need to adjust 5th wheel hitch to accommodate the extra height when compared to the older style bed rails.
I have a Curt A16 5th wheel hitch and a Curt gooseneck plate. Both of these fit perfectly. Definitely much cheaper than having to buy new 5th wheel hitch and new gooseneck ball for the puck system. Saved me about $1400
it fit perfectly in my RAM 2500 2022 , it reduce the height by 3.5 inch from my original roller Curt set up, since I have air suspension in the back I will simply said be careful when you disconnect because the back of the pick up spring upward when load is removed. The reason I switch was the high of the roller sytem and the puck was way too high for my fifth wheel.
This was an easy install. Very heavy and ready to pull my trailer!
An excellent experience with etrailer.com

Assembly was supper easy. Just like the previous one I had for GMC. This product has better handles. I have not towed with it yet. But should be good to go.
Heavy and well built. Great that I was able to use my Curt hitch when I bought a new truck with the puck system. Etrailer is a great company with great people. Fast shipping
I decided to order this adapter because I bought a new truck and wanted to use the 5th wheel I had. Fred at etrailer was a tremendous help. He took the time to go through everything and find the right one and explained it all very well. Believe me, I was very skeptical on ordering but Fred assured me this would work on my 2025 Ram. I was pleasantly shocked when I got it and everything went right into place. Very easy to install. Thank you so much Fred for all of your help!!
Cammi, my customer support person was awesome. I told her what I needed and she recommended to perfect hitch. I was impressed with her knowledge of their products and how fast it was delivered. Installation was simple as long as you follow the very well written directions.

My hitch is working great still. Easy to use no issues.
I bought a 2023 Ram 3500 that had the factory pucks in it, so I needed this adapter so I could continue using my B&W Patriot hitch. This fit my truck perfectly and my hitch fits this adapter perfectly. Even better than it fit the rails in my old truck, actually. This does raise the hitch probably an inch higher that it was, so be aware of that. One part of the instructions is out of order. How to adjust the locking mechanism is at the very end. You need to adjust each one as you go. Other than that, it was very intuitive and easy to put together. I did use a little blue Loctite on the nuts, but that's me. This thing is beefy. I'm sure it will last a long time.
It is what we needed for our new ram truck shipping was fast. And we had issues with ups but this company handled everything in a timely matter. Very happy with this purchase. Thanks for everything.
Every fast shipping. Arrives a day early than what it said when I ordered it. This is the second time I have ordered from them and both times order’s arrived on time or before. Will order from them again.
I previously owned the Curt A16. We needed a larger tow capacity so we purchased the A20 and decided to buy the S20 slider base as well. Too many sharp turning issues with our 6’8” Chevy standard bed HD3500 during maneuvering. The S20 slider should eliminate this issue. Also I love the design of both the A20 and S20.

This was a great purchase and it’s made backing into tight camping spots so much easier. 100 satisfied with this hitch and slider system!
Packaging was in great shape, arrived when trailer said it would, and it went together with ease! My Andersen 5th wheel hitch fits perfectly in the adapter, so we are all set!
